Tabriz city in East Azarbaijan province also has a high potential in terms of having natural attractions and suitable climatic conditions. In this research, in order to evaluate the suitability of a suitable ecotourism location using the Analytical Hierarchy Process (AHP) and using the method (OWa) and Geographical Information System (GIS) were first examined according to the situation of the study area and the opinions of nature tourism experts and the evaluation of effective options in evaluating the spatial suitability of ecotourism development and all the options were converted into information layers and finally Using the AHP FUZZY technique with the OWA method in the GIS environment with the combination of 16 layers of information, the spatial compatibility map of the ecotourism development of the study area was prepared. Based on the results obtained from the spatial suitability map of ecotourism development in the study area, 52493.8 hectares or in other words 23.48% of the area is at a very favorable level, 50017.8 hectares or 22.38% of the study area is favorable and 1 51709/ or in other words 23/13 is at the average level. Also, the results of this research showed that the most unsuitable areas for the development of ecotourism include 24659.3 or in other words 11.03% of the entire area. The central region of Tabriz has a high potential for ecotourism. This area is in a very favorable condition in terms of research criteria. Thus, in terms of the most important criteria, i.e. distance from natural landscapes, distance from historical, religious and ancient attractions, and distance from facilities and services, due to its proximity to neighboring cities, including Tabriz itself, as the capital of the province, it has a good status compared to other parts of Tabriz city.

Land subsidence is an environmental phenomenon of the gradual or sudden subsidence of the land. The purpose of the present study is to evaluate the land subsidence in Shabestar plain of East Azerbaijan province. Using Small Baseline Subset (SBAS) time series analysis method, the crust surface displacement rate between 2018 and 2021 is investigated. The maximum subsidence is seen in the southern and southeastern parts of the plain with a maximum rate of about 8 cm per year in the direction of the satellite line of sight. Also, using AHP the conditioning factors are weighted and the land subsidence susceptibility (LSS) is modeled using spatial analyses. Thereupon, Shabstar plain was classified into five regions with the LSS: "Very High": 3%, "High": 20%, "Moderate": 25%, "Low": 33% and "Very Low": 19% of the total area of the plain. To verify the accuracy of the subsidence susceptibility model, the displacement map obtained from radar interferometry was utilized, the area under the ROC curve of 86% confirmed the good prediction accuracy of the model. Also, the model was assessed by performing sensitivity analysis for most important conditioning factors. The introduced model can provide useful and reliable information for managers and decision-makers of the region for the effective and timely 'prevention' and 'mitigation' planning with low cost and time.

Governments and societies have historically divided their territories into different regions and areas to better manage their land and preserve the territorial integrity of their country. This practice is now related to the concept of spatial planning, particularly "Territorial Zoning". Territorial Zoning aims to achieve cohesive management and the National Division of Labor, as well as utilize the potential of different regions to reduce territorial inequalities and imbalances. In Iran, Territorial Zoning has been implemented by various organizations over the past decades, with the most recent division into nine major regions in 2017. In this descriptive-analytical research, the extensive literature on Spatial planning and Territorial Zoning plans in Iran is reviewed, providing a comprehensive history of these programs. The research then critiques and analyzes these programs. The most important criteria influencing land zoning are identified and prioritized using the Analytic Hierarchy Process (AHP) method and the opinions of experts. According to the findings, the most important criteria for Territorial Zoning are "cultural-social", "defense-military", and "political-administrative". The sub-criteria of "environmental issues", "level of regional development", "population distribution", "government pattern and type", and "threats and security issues" are also deemed important. Based on the findings and results of the research, the authors propose their own Territorial Zoning plan in the form of ten major regions. This research contributes to the understanding of the history and current state of territorial Zoning in Iran and provides valuable insights for policymakers and practitioners in the field of Territorial Zoning and spatial planning.

Introduction Perhaps housing can also Introduced as the main factor and objective of shaping skeleton and structure of the city, because firstly whatever of cities explicitly at citizenry possession, are homes and housing; secondary, home is a space for birth and growth and maturation of man at individual or among the family situation; Third, home is a place of activity establishment and growth of family which that is the smallest social unit; Fourth, housing is the main and the most basic factor of identity of man and society and the basis of unification or vice versa Scattering of them (Naghizadeh, 2013). Affordable Housing, is a housing that its features based on the cultural values and their regeneration and promotion in the society and toward the obliteration of self- alienation and return to itself; and cultural activities and the introduction of national identity and searching the special methods in format of qualitative policies and executive policies in it is necessary (Naghizadeh, 2012). Codification of housing basics by using the foundations of Iranian- Islamic architecture of the past decades and Islam monotheism worldview principles and also requirement of pay attention to improving the quality of housing and transformation in methods of construction of buildings is inevitable (Naghizadeh & Asadzadeh Birjandi, 2013). Consideration to muslim housing in Islam is knot with insight to divine verses and this matter sacredness of the human living place. Sacredness that explain the unique features of good home and at muslim human dignity; that pay attention to each of them provide human heavenly and earthly bliss (Hoseini & Samimi, 2015). City housing and residential context are as the main manifestation of appearance of Islamic values (because of filling major section of the city area) can be in the both of old and organic urban fabrics, that based on their period native and cultural conditions, and evolved over time and remained up to now and investigated and evaluated in new fabric of cities, which forms based on urbanism methods and new patterns. This research, look for two main objectives, firstly, analysis and assessment of the housing current status of old and new neighborhoods in Urmia city based on Islamic housing indicators, secondary, analysis and assessment of Iranian- Islamic indicators status of old and new neighborhoods of Urmia city, so that this way able to achieve the strengths and weaknesses of observe of Iranian-Islamic indicators with the matching of results.Data and Method Islamic housing indicators classify in two categories of quantitative and qualitative. Quantitative indicators include: housing area, housing facades, housing quality, housing resistance and safety, housing orientation to the qibla, existence of green spaces in the neighborhood and qualitative indicators include: the use of natural light, comfort in housing, housing relation with nature, non- overlooking into housing, accessibility to housing. In the first stage, quantitative indicators were extracted through the library studies and in the next step housing quality indicators was evaluated through questionnaires. For this work, 330 number of questionnaires through Cochran formula was obtained that among residents of the studied neighborhoods were collected. Also, for weighting the Islamic housing indicators, 30 numbers of expert questionnaires were set, which 15 numbers of questionnaires were polled by experts of seminary courses and 15 numbers of questionnaires were polled by academic experts related to housing. AHP model also has been used for weighting the intended indicators by expert questionnaire. To analysis and assessment of the studied neighborhoods situation with the Islamic housing indicators and also for assessment of Islamic- Iranian housing indicators in the studied neighborhoods, TOPSIS method was used. After initial analysis and assessment of condition by using the output of TOPSIS, was proceed to the pathology and identify weaknesses of indicators, which finally was leaded to present solutions in order to reduce the problems related to having Iranian- Islamic indicators in the studiedneighborhoods.Results and Discussion According to TOPSIS method results, Behdari neighborhood as one of the new neighborhoods of the Urmia city, with consideration of Iranian- Islamic indicators toward the Mahdi- al- qadam neighborhood, which that is one of the old neighborhoods of the Urmia city, is more favorable. With the return to the indicators, respectively determine that, resistance and safety, housing area, comfort in housing and overlooking have the greatest impact in undesirable position of Mahdi- al- qadam. In other words, having weakness of mentioned indicators in the Mahdi- al- qadam neighborhood has caused that this neighborhood toward the Behdari neighborhood placed in a lower position. Therefore, in planning for the Mahdi- al- qadam neighborhood its necessary that solutions be explained to improvement of indicator status. Also, according to the results presented in table number 3 that shows the ranking of indicators in neighborhoods, resistance and safety indicator has been ranked first. Comparison between situation of the Mahdi- al- qadam neighborhood and resistance and safety indicator shows having major weakness of mentioned indicator in Mahdi- al- qadam neighborhood.ConclusionConducted analyzes in this research showed that among the chosen indicators, overlooking indicator as the factor that covering visibility and Create privacy lies in itself, also it is important from the point of view of the Seminaries and academic experts, but unfortunately this indicator is among the weakest indicators in Mahdi- al- qadam and Behdari neighborhoods and needs more attention. In both neighborhoods, interesting point is located the resistance and safety indicator in the highest position among the other indicators, that shows favorable situation of this indicator among the other indicators. Also, the results of comparing two neighborhoods represents this point that Behdari neighborhood, with consideration of all Iranian- Islamic indicators, is in a more favorable situation toward the Mahdi- al- qadam neighborhood.

In recent decades, cities have grown organically and urban areas in a short time have been several times its original size and city development has been the forms of the individual components, without planning, uncoordinated that urban sprawl pattern is the main feature. Urban Smart Growth cities were developed for deal with problems of sprawl. The case study is Maragheh city. The research method is descriptive and analytical. In this paper, the capacity of Maragheh, using the development from within the main principles of smart growth is about the sprawl, is marked. Indexes such as population density, rate of open space, building quality, access and permeability, compressibility, etc. are used. Neighborhoods with using Analytical Hierarchy presses (AHP) to prioritize and ultimately the level was estimated for each of them. Results show that in 1392 the gross population density of 59.3 persons per hectare is which is considered very low density and On the other hand there is a lot of undeveloped land, 333 hectares, Uses of unconventional urban, and the average per capita level of infrastructure per person is 162.3 square meters. With this description, using the principles of smart growth and in particular, the principle of development from within and Suitable density, Building on wasteland and etc., sprawl can be prevented the sprawl.

Abstract In this research, by using 10 natural criteria and AHP model, Tabriz district was studied from natural environment perspective to identify the optimal location for construction of Maskan- Mehr and compare the current Mehr housing location. The method of this study is descriptive-analytical and the data were collected by documentary and field study methods. According to the proper zones identified for localization of Mehr housing in Tabriz district and since all zones were not optimal and lacked capability of planning, so by using TOPSIS, SAW and MORIS, the optimal zones were prioritized from implementation perspective. Also, the analysis of sensitivity of the identified zones was investigated based on 10 localization criteria. The results show that there are seven proper zones 10 km of Tabriz that have the best conditions for localization of the Mehr housing according to studied criteria. Also, ranking models show that the first zone is near to Tabriz- Maragheh road. The results show that Mehr housing in Tabriz that selected based on the economic conditions and land ownership issue could be localized in a proper environmental conditions near to Tabriz to consider environmental and natural disasters in addition to economic support of the owners of these dwellings.

Canola is the world third leading oil seed after soybean and oil palm by producing 15 percent of the global plant oil. Climate, topography and lands capability are the most important environmental factors on which the crop production capability in a region depends. Therefore by evaluating these factors one can identify suitable lands for canola cultivation. In the present study, the climatological data such as temperature, precipitation, growth degree day, relative humidity, freezing days, and sunshine hours were collected from the West Azerbaijan province synoptic and rain gauge stations (since their installation untill 1388) which were associated with the phenologic stages of canola growth. In addition to the climatological data, earth resources like topographic layers, lands capability, soil depth and land-use were analyzed focusing on the climatological and ecological requirements of canola. After generalizing the data and processing by using ArcGIS, their corresponding information layers were derived. In order to prioritize and assess the criteria and information layers in relation to each other, the multi criteria decision method was employed based on analytical hierarchy process. Then, combination and spatial analysis of the information layers using TOPSIS model and GIS capabilities were done and the final capability ecological evaluation layer for canola cultivation was produced. Based on the obtained results, the province lands were divided into four categories of highly suitable (%18.6), suitable (%34.4), moderate (%32.1) and weak (%14.7) lands on the basis of the environmental and climatologocal potentials for canola cultivation.

Increment of soil carbon is an appropriate method for reducing atmosphere dioxide carbon density resulted from foresting in the unutilized and destroyed lands and its optimal management due to increase of concern about universal heating and changing of climate. According to universal heating and expansion of urban industries issue in the air pollution; capacity of Tabriz Province lands in establishing of parks has been investigated by employing AHP. The data were collected by available basic maps and spot 2005 satellite images and also field studies. The zone digits of maps were converted to criterion maps (slope, direction, height, land usage, geology, soil, city, communication network, village and rivers) by using spatial information techniques and they were valuated for paired comparison. The value of each scale was considered according to capacity of each unit. The paired comparison of the spatial information techniques criteriawas conducted by using Marionian attached program in GIS and the studied criterion weight were calculated. Then the final map in raster format was extracted by using each weight and was categorized in five classes range from very weak to very good and the best location was extracted with an area about four percent of the whole Province

This article aims to evaluate sensitivity of Goijabel basin lands in landsliding based on GIS and AHP. The main reason for selection of this basin for research is to observe the current landsliding in the region by the author and environmental preservation attitude of the authors. This basin is one of the sub-basins of Aharchi in area of 7406 Hectares with geographical statues of 46,47,21/26 to 46,56,53/64 east longitude and 38,21, 42/13 to 38,27,39/04 north latitude. The criteria selected for analysis of landsliding sensitivity in the study basin involve nine parameters (slope, aspect, height, lithology, fault, road, landuse, precipitation and main water ways) extracted from basic maps, field studies and spot satellite images and their primary valuation was conducted by using GIS techniques in five layers relative to the effect of each measure on incidence of landsliding. Then pair comparison of the layers was carried out by using Mariyoni attached program (AHP extension) and final map of the land sensitivity in landsliding was extracted. The results of landsliding sensitivity analysis in Goijabel basin showed that the most effective factor in land sliding is lithology with weight of 0.3113 according to the highest weight and then the height with minimum weight of 0.0178 is the criterion with lowest effect in landsliding. Also the analysis of landsliding danger in the study basin shows that endangered lands with high sliding capability involve 1222 ha which cover %16.5 of the total regions.

The selection of suitable location for implementing of flood spreading project and artificial recharge of aquifers is an important step. To assess this purpose, the Geographic Information System (GIS) conceptual models and decision making systems were used. Regarding different mentioned criteria, it is not possible to use GIS without appropriate Multi-Criteria Decision Making (MCDM) technique. The main aim for this research is to access the suitable location for flood spreading by using the most efficient criteria and classify them into several groups. Consequently, major factors such as slope, geology, geomorphology, hydrology, infiltration rate, cover and environmental impacts of the projects should be considered in the process of selecting appropriate site for artificial recharge through flood spreading. Also evaluating accuracy and application of conceptual models such as Logic Boolean, Multi classmaps, Binary Evidence, the Analytic Hierarchy Process (AHP) have been noticed. In this research, nine physical and environmental efficient variables essential for locating of flood spreading are used. The results indicate GIS-based data combination for ranking suitablelocation of flood spreading by itself, though it is not reliable enough. Also evaluating accuracy of models shows that accuracy of Binary Evidence model for identifying and ranking suitable location of flood spreading is more than that of Boolan model and the Multi class maps model can give better insights to create more realistic output scenarios The most important step in flood spreading process is to define optimal site. The Analytic Hierarchy Process (AHP) is an approach that is suitable for dealing with complex systems related to making a choice from among several alternatives and which provides a comparison of the considered options. In the present research relationship between GIS and Multi-Criteria Decision Making analysis has been investigated in order to find optimal site for flood spreading. The research emphasized the capability of resultant map to be used in site selection for flood spreading.

Iran has a dry land with very small amount of precipitation so that its average rainfall is less than one third of average rainfall in the world. Nowadays, with increase in population demand for food increased. Therefore, utilization of water resources extended much more than the past. This amount of consumption was more than the amount of ground water resources. In other words, input source become less than output. Therefore shortage of ground water resources should be compensated through artificial recharge of ground water resources.
The purpose of this study is zoning watershed for artificial recharge ground water. The analytic hierarchy process (AHP) is one of the most efficient techniques designed to multiple criteria decision making. This technique allows formulation of complex issues as hierarchy and also provides the possibility to consider various quantitative and qualitative criteria in question. To ensure the final results, potential layer of study area was provided in raster calculator, weighed overlay and weighted sum methods. The results show that among the three methods mentioned above raster calculator method allocated the maximum of area to high potential against weighed overlay that allocated the minimum area. But the weighted sum method is between the two methods and results of its confidence is higher. Among these, zones with highest potential are based on more coarse alluvial sediments and most areas with the highest density and zones with lowest potential both coincide with highest altitutes with the lowest penetration and steep slope and the low areas with high density of gypsum deposits and high rate of evaporation and temperature. The results of this study can be used in environmental management of groundwater resources and also the fruitful exploitation of optimal design of water resources and prevention of over exploitation of which can be productive.
