The Islamic city is an idea that has raised many questions about its nature and characteristics. In this regard, various scientific systems have approached it from different angles and tried to explain it. However, a critical review of the relevant literature reveals a high volume of misinterpretations and confusions about this idea and its related concepts, topics, and goals. Accepting the fact that the existence of mosques, domes and minarets in the context of a city can not mean that the city is Islamic, makes it clear that it must be in other elements and components and we should look for signs of Muslim life and patterns of an Islamic city not only in the body, but also the spirit and identity of cities. In the present study, the drivers of the Islamic city were extracted (qualitative part of the research) by studying valid jurisprudential sources (Quran and Nahj al-Balaghah), and then the quality of their realization in the metropolis of Tabriz was measured. The results obtained from the qualitative part of the research place the drivers of the Islamic city in three categories: monotheism and unity, justice and security. The results of statistical analysis show that Islamic manifestations and the realization of its principles in the city of Tabriz is not prosperous and requires planning to improve the quality of realization of these indicators

A resilient society is able to respond positively to changes or tensions and is able to maintain its core function as a society despite tensions. Natural hazards are one of the main threats to human societies. They overshadow their resilience. Earthquake is one of the most important natural disasters. Earthquakes are basically considered as uncontrollable phenomena. On average, there are 27 catastrophic earthquakes in the world every year, during which 19,000 people die and 36,000 people become homeless.Among these, the geographical area of Iran is one of the accident-prone areas where many natural disasters such as earthquakes, floods, storms, droughts, firefighting activities and desertification are examples of which occur every year. In the meantime, the city of Tabriz is one of the largest and most important cities in Iran, which is located in a very high risk area, adjacent to the Tabriz fault and having a population of 1558693 people and the existence of huge human, cultural and History introduces Tabriz as the most dangerous city in terms of earthquake riskAccordingly, Tabriz fault is the most dangerous fault in the country

Senior tourism is receiving a lot of attention due to its capabilities and competitive advantages. Qom city is the second largest pilgrimage center in the country in national level, a potential market that can use its competitive advantage in attracting senior tourists by removing barriers of seniors’ travel.The purpose of this study is to provide a framework for identifying the direct and indirect impacts of barriers affecting the development of senior tourism in Qom city. The barriers to senior tourism development are classified into four main sectors of economic, social and cultural, managerial and organizational, government attitudes. This research is an applied research and the method is descriptive-analytical. Survey and library methods were used for data collection. The statistical population of the study consists of senior tourists and experts in tourism. Data analysis was performed using SPSS software. The results indicated that four factors have a positive effect on the lack of development of senior tourism. The results of T-test also showed that all barriers were higher than the criterion level at the significant level of 0.05 and the highest mean is allocated to economic barriers (5.17) and lowest mean to managerial and organizational barriers (2.10). The most influential factor on the lack of development of senior tourism is economic barriers (with beta coefficient of 0.643) which explains 52% of the variance of senior tourism lack of development. The Tolerance coefficient of 0.923 also indicates that economic barriers are strong predictor and criterion.

Urban regeneration, as a comprehensive and integrated operational vision and approach, seeks to improve the economic, social, physical and environmental conditions of an urban community that has been subject to change; in a way that ultimately leads to a sustainable economic, physical, social and environmental development and improvement. Meanwhile, one of the ongoing problems of human settlements is biological hazards and epidemics such as malaria, influenza and coronavirus (Covid virus 19), which has faced many challenges in different parts of the world, especially cities in various economic, social, environmental and other dimensions. Therefore, there is a need for a framework for planning and regeneration approaches to future cities in order to deal with such risks. For this purpose, the present study has been written with the aim of developing applied knowledge in identifying the factors affecting the realization of sustainable urban regeneration of Tabriz in the post-Corona era. Therefore, the research method is applied in terms of purpose and analytical and exploratory in nature, and data analysis has been done using the Delphi method (15 elites and managers) and the application of cross-impact analysis technique in Micmac software. Based on the obtained results, the most effective among the studied components for sustainable urban regeneration of Tabriz in the post-Corona era are related to the components of information technology management in organizations in charge of urban affairs and emphasis on knowledge-based and knowledge-based management, emphasis on urban governance and urban management system integration, to create a mechanism to achieve the participation of citizens, private institutions and government organizations in the urban management system and the realization of a holistic view in the face of complex issues of cities.

Female spaces are important topics in urban studies. The performance of some of these spaces (such as jewelry stores) is such that they attract women's population in a meaningful way without the requirement of limiting the presence of men. Therefore, the present study intends to evaluate the pattern of gold shops in the urban spaces, while choosing two regions with different income status from Mashhad and show the visible differences in the distribution of such spaces (according to the income level of each region). and what unwritten rules does this model follow? The descriptive-analytical study method and the statistical population also includes all gold shops located in areas 1 and 5 of Mashhad (including 630 gold shops). In the first step, after creating a location database in ArcGis, the location of gold shops was determined based on the information available in Mashhad Municipal Union Bank. In the continuation of using 7 variables (from the locational characteristics of gold shops and the elements of the spatial structure of each region), including the absolute location, size, time of establishment of each gold shop, proximity to surrounding uses, roads and communication arteries, the population and the population of women, the spatial differences regarding the establishment of gold shops were investigated. . The investigated models include "density model", "center of gravity", "standard distance", "nearest neighbor", "spatial autocorrelation" and "spatio-temporal model". The results show that in developed areas, women's spaces are less consistent with the distribution of women's population, while in low-income areas, women's spaces are more compatible with local elements such as proximity to bus stations, local arteries, and residential spaces. . At the same time, the common point in this regularity is the prosperity of these spaces over time. which seems to lead urban spaces to become more feminine in the future.

Today, climate change and habitat loss are the biggest threats to wildlife. Therefore, accurate information on ecology and habitat requirements conserve species from these changes and identifying the most important factors to attract species and the development of habitat suitability maps can be considered a species protection process. After leopards and cheetahs, Caracal is the third biggest member of the cat family (Felidae) in Iran that has a key role in controlling of rodent populations and its habitat is mostly in arid areas. Accordingly, the aim of this study is to consider the effects of climate change on Caracal habitats and the distribution of the species under two climate scenarios RCP2.6 and RCP8.5 in the period of 2061 to 2080 in Iran by using the maximum entropy method. In this study, four groups of environmental variables are used: climat, topography, land cover, and land use. The results showed that distance from the conservation network, distance from sand dunes, and distance from dense forest areas had the greatest impact on the selection of suitable habitat for the Caracal at the present time and for the future time, the variables of mean temperature of warmest quarter and elevation had the highest importance on the distribution of Caracal. In addition, the study of Caracal's habitat suitability maps revealed that these species currently occupy only 13.2% of Iran, which have only 48.2% overlap with the current conservation network. While, in the future, the desired habitat rate of the species under the scenarios of RCP2.6 and RCP8.5 will be reached 30.9 and 27.4, respectively, and the amount of overlap with the current protected network will be reduced to about 66%, and the amount of overlap will have arrived at 17.8%.

Today employment is one of the most important indicators of development in the countries. The analysis of the employment process and its structure across the country and its various areas requires accurate knowledge of the potentialities and their composition in the areas , to create balanced planning and employment in each area. This research is descriptive-analytic and aims to analyze the spatial distribution pattern of public and private sector employees in Iranian Townships. The statistical population consists of 397 Township all over of Iran, whose statistics and data were from the general census of population and housing in 2016. In this regard, after collecting the data and theoretical studies of public and private sector employees, the spatial automation correlation model based on the Moran's I index and Spatial Statistics Tools used for spatial and Hot Spot Analysis with Rending. The results of data analysis indicate that the distribution patterns of public and private sector employees in the Iranian Townships is clustered (was not distributed uniformly in the different Townships). Also, according to the analysis of Hot Spots, the distribution of employees in the public and private sectors was observed, with the highest in Tehran and centralized in a radius of approximately 300 km from it (although Tehran itself is confined with a 95% confidence level), and the rest of the Townships have more balanced distributions.

From urbanization, the phenomenon of the urban temperature island follows which the city rises and increases from energy to cool. In this research, the role of local factors in the creation and development of heat islands in the city of Ahvaz during the hot period from 2000 to 2015 was investigated using Landsat 7 and 8 satellite data. In order to evaluate the biophysical changes of the land surface in Ahvaz city, the changes of vegetation difference indices were taken by Tokanga-Tag threshold method. By using the kriging method and the low speed zones of Ahvaz, the thresholds of the closest and maximum temperature of Ahvaz city, it appears that this change can cause a change in the local climate. The results of Moran's spatial autocorrelation are a confirmation of the lack of spatial correlation of ground surface temperature in Ahvaz. The evaluation of the northern maps showed that as we move from the southern regions to the northern regions, the temperature increases due to the increase of green space and the increase of barren lands. There is a sharp temperature difference between the central and suburban areas of the city, because of the establishment of industrial companies, District 8 has formed the most stable islands in this area of the city. Residential areas have had less impact on the creation and expansion of thermal islands than industrial and barren areas.

Widespread climate changes and their consequences on the economic, social, political, etc. fields have forced global societies to take serious decisions and change development strategies. Reducing greenhouse gas emissions, which is an important factor in global warming, is one of these strategies. Cities, as centers of population and a variety of polluting activities, are important centers of greenhouse gas production. This issue is more visible in developing countries including Iran. In this regard, this research tries to identify the components and indicators that affect urban carbon reduction with the aim of investigating the theoretical foundations and background, and to analyze and present them for future urban plans and strategies. For this reason, the current research was conducted using confirmatory factor analysis and structural equation model, and it was conducted in survey and Desk search. The methodological approach of the research is also quantitative in terms of the type of data. The main tool for data collection is a closed questionnaire with a Likert scale. SPSS21 and AMOS23 software were used for data analysis. Finally, various fitting tests were performed and their usefulness was evaluated. The obtained results show that different components and indicators are effective on urban decarbonization with different impact levels. Factor loadings indicate the extent of their influence on the subject. Among the components and indicators, the options related to the preservation of forests, clean and pedestrian-oriented transportation, use of clean energy, etc., have received the highest factor load and have a warning sign on the policies adopted by the responsible bodies in the field. Moving towards the mentioned components is a big step towards forming one of the three sides of sustainable development.

Understanding the climatic potentials of the regions is very important for the diversity and talent of agricultural products. Barberry, one of the products of Iran, suffers from climate change and anomalies. In the present study, the phonological stages of barberry tree without any basis of field observations in Ghaen synoptic meteorological station were determined. To measure the accumulation of cooling needs based on the cold clock model and the Utah unit, the statistics of 18 valid meteorological stations from 1987 to 2017 on an hourly and daily time scale were used. The results showed that barberry needs six phonological stages to complete the growth period from early April to late November. The highest temperature requirement occurs in the ripening stage until fruit development. The cooling requirement of barberry tree in different stations varies from 1050 to 1960 hours depending on climatic conditions. Field observations showed that seedless barberry does not take on a full and commercial color if it does not meet the need for sufficient cooling. The study area was zoned according to the models of the cold clock and the Utah unit, based on which Ghaen and Zahedan stations have the highest cooling needs. Based on the validation indices of different models estimating the need for cooling, the root mean square criterion was used and the results show that the cold hour (CH) model has a higher performance due to the fact that the root mean square (RMSE) is less than the other model.

Problems caused by climate change are one of the most important environmental crises and threats of human society, especially in urban environments. In the city of Tabriz and in recent years, due to the growth of the population, a lot of migration from other cities, traffic, the development of industries and production centers have caused an increase in the production and distribution of pollutants. Based on this, in this research, attention has been paid to the evaluation of the quality of dust occurrence in the years 2019 and 2018. The concentration of dust particles in different areas of the studied places varies depending on the geographical location, topographical, climatic conditions and also their origin, both internal and external. Based on the results obtained from the analysis of laboratory results and field studies, in the Tabriz region and during the research period, the concentration of lead metal in dust is moderate for adults and severe for children, and the risk of mercury metal for both the elderly and children. It has been intense. The adverse effects of cadmium metal have been very severe in children and adults. On the other hand, the high air temperature in the city center and the formation of thermal islands in it causes local winds from the suburbs to the city center. With the transfer of pollution from the suburbs to the city center by these winds, the pollution situation in the city center also increases.

One of the important conditions for optimal use of land is obtaining information about landuse patterns and their changes over time. Landuse is usually defined based on human use of land, emphasizing the role of land in economic activities. Today, remote sensing technology is considered as the main element in landuse monitoring. The aim of the current research is to extract landuse maps for the years 2000 and 2021 in FirozabadKhalkhal region and to investigate the changes made in the studied time period in the region using the images of ETM and OLI sensors of Landsat. Also, checking the capability of basic pixel and object-oriented methods for landuse classification is another purpose of this study. In the current research, the object-oriented technique nearest neighbor algorithm and the vector machine method supporting the pixel-based algorithm have been used for landuse classification. Then, to verify the accuracy of these two methods, the overall accuracy and Kappa were extracted. The results of this evaluation show the high accuracy of the object-oriented method in extracting land use classes. Based on the results of the detection of landuse changes in the studied time period, the highest amount of changes occurred is related to the use of good pasture to poor pasture with a value of 51.72 square kilometers, followed by forest to good pasture with a value of 30.11 and the lowest changes It is related to the use of pasture and water with the amount of 0.03 square kilometers. The reasons for these changes are the increase in population, indiscriminate grazing of livestock, incorrect and illegal use of different lands. The use of more parameters such as scale, shape, compactness, color, texture, smoothness criterion and pattern for landuse classification in the object oriented technique can be considered as an innovation of the present study.

In this study, using images of Landsat-8, Landsat-7 and Sentinel-2 satellites in the coding environment of Google Earth Engine, their uses and changes during the two periods before and after urbanization (from 2000 to 2008 and from 2008 to 2019) will be categorized and then the next five-year development forecast of Sahand city (until 2025) will be made. Perceptron multilayer artificial neural network (MLP) method has been used as a method for predicting spatial multi-criteria decision making (MCDM). The independent variables used in the present study in predicting the physical development of the city are land price, type of use, slope, slope direction, altitude, distance from urban areas, distance from waterway network, distance from fault, distance from network Passages (main and secondary). The results of classification of satellite images showed that the physical development of Sahand new city has been done in order to turn barren lands into urban land. In addition, physical development was built to turn cheaper land into areas. The built lands have been greatly developed and from 64,155 square meters in 2000 to 682,192 square meters in 2019. Among the image classification methods for land use extraction, the SVM method was the best method and also the Sentinel-2 satellite images had the highest accuracy. The multilayer perceptron artificial neural network was used to predict the future physical development of the new city of Sahand, which according to studies, the development is predicted in directions that are based on the cheapness of the land and the limitations. Geomorphological is like slope and altitude.

Urbanization, which began in simple, centralized societies that were primarily reflections of different social forces, has led to significant environmental changes in cities, especially with the increase in urban population, which has led to the collapse of the urban services distribution system and the unequal distribution of citizens using urban services. The current study aims to evaluate the distribution of urban services in Yasouj city from the perspective of spatial justice and to identify the root causes of imbalances and inequalities to offer a suitable solution. This is because the issue of spatial justice is crucial to the distribution of urban services. This article used a descriptive-Causal research method. The distribution pattern of urban services was determined using the Average Nearest Neighbor (ANN) and network analysis index, and the contributing elements in the imbalance of urban services were determined using the Delphi technique. The relationship between the variables, their level of influence, the prioritization of each variable, and eventually the relevant measures to lessen the imbalance of urban services was determined after the elements in the MICMAC program were found. The results collected demonstrate the cluster distribution of urban services as well as the centralized, unprincipled, and ineffective distribution of these services at the level of Yasouj city's regions and districts. The analysis's findings also indicated that the unequal distribution of urban services in Yasouj city is mostly caused by permissive rules and regulations, high economic rents, and intense owner pressure. Finally, under the findings, suggestions for establishing spatial justice in the city of Yasouj and a fair allocation of services were made.

Skyline can be an effective component in explaining the spatial and qualitative features of the urban landscape. Ignoring this important category, as well as not observing the proportion between the height of the wall and the width of the street, leads to the creation of an abnormal appearance and in some cases, excessive confinement in city streets. It is obvious that the streets do not only have a physical dimension, but also represent life and dynamics in communities and cities. Therefore, skyline can be an effective component in improving the quality of the urban landscape.In this research, the library studies methods and field surveying have been used. ArcScene was used for height simulation and evaluation of the appropriate as well as the required analysis (skyline, skyline graph, etc.). The selected areas in the city were from the new fabric (less than 20 years old), middle fabric (about 50 years old) and old fabric (more than 50 years old). The results obtained from the skyline graph analysis show that the skyline pattern of South Shariati Street (old fabric) with an average of 74.06% has better view of the horizon than Imam Khomeini street with an average of 63.5% and Takhti street with an average of 55.66%. Also, this research explains the reason for the relatively irregular skyline caused by high density sale in Tabriz metropolis, the method of densification and height zoning of that area. The results of 3D analysis show the existence of a direct relationship between the heights of building. In this way, the more proportional the height of the buildings, the more open the space will be, and the wider the passage, the wider the radius of the skyline graph will be.

This article proposes ‘urban acupuncture’ as an emerging concept in the Iranian urban planning literature. It has endeavored to explain urban acupuncture and the learned lessons learned in the urban spatial analysis process. According to the model, the best way to provide structural and infrastructural development is to employ the existing potentials of the city within a network arrangement, valuing soft approaches, like urban acupuncture, to be able to recognize thousands of diverse points in the city for small-scale but effective interventions in the form of a coherent network. Urban acupuncture as a tool with a holistic and networked view of the city identifies the abandoned points. It reintegrates them as new intervention spots into the life cycle of urban green spaces to achieve the sought urban structure. Using the "urban acupuncture" approach with a deductive-analytical methodology from a network perspective in the historical center of Shiraz, this study tries to introduce the existing potential pattern of the abandoned points in the course of moving towards urban ecological sustainability. Thus, it can achieve procedural unity by development based on existing urban environment potentials. Finally, by applying the concept of urban acupuncture, the research tries to compare the urban green network and explain the necessity of this approach by orienting the urban redevelopment to rediscovering a wide range of repressed yet developable parcels within cities as an analogical framework. As such, this process could provide opportunities for designers to intervene in the neural network through the acupuncture approach by remodeling the ecological network and structural development of green spaces to improve urban environments.

One of the most important consequences of the rapid growth of urbanization and the physical development of the country's cities in the past decades is the breakdown of the distribution system of urban service centers, which has become the basis for social inequality of citizens and the level of enjoyment of urban services. In the meantime, medical services are of particular importance, so that the weakness and inefficiency of the management in the matter of providing optimal services in this field will have extensive negative consequences. In this research, we investigated the access of the population to the hospital as an integral part of a social organization that is responsible for providing complete health care including treatment and prevention measures in the population as an important measure in the health of the city in smartness. we paid In the current research, using the 2-step method of the floating basin, using network analysis and pre-processing of population blocks, to prevent the inflation of supply and demand, we have created the access limits of the population to the hospital. The results show that according to the growth of the urban population and the direction of these changes in each studied urban area, the population's access to the hospital is poor and limited population blocks have appropriate access, inappropriate distribution and dispersion in the location of hospitals and lack of planning regarding Increasing the approved beds and activating the beds are the things that cause the lack of easy and quick access to these services for the population of southern areas of Tehran.
