Now a day, environmental crisis resulting from uncontrolled human intervention has caused ideas on human interaction with the environment and also the concept of ethics and its importance in the preservation and optimal utilization of the environment considered by researchers. Due to this, the need of evaluation of the current human approaches towards nature regarding moral and ethical aspects will be emphasized. The existing study was conducted to analyze the effects of social capital in rural environmental ethics. Type of research is applied and its nature and method is Descriptive-Analysis. Data collection method is library and fieldwork (questionnaire) and data analysis was done by using descriptive (mean, standard deviation) and inferential statistics (chi-square and linear regression). Population of The study were, Chaypareh Bala villagers of Zanjan city: 15022 people inhabitants in 3584 households in the 1390 census. Analysis Unit is rural households who are living in the village, in order to plan internal consistency and reliability of indicators, Cronbach's alpha coefficient was 0.86. The results indicate, there is a statistically significant difference among independent variable social capital and dependent variable environmental ethics. Investigations of existing study show, based on social capital a significant difference obtained in rural environmental ethics and there is a direct relationship between them. So, we can say that with increase social capital, the environmental ethics increase too.

Determine appropriate areas for optimum use of the flood is one of the most important factors determining the success of watershed management plans that collected rainwater, with the intent varies. That the main objective is optimization and operational management of rain water based on demand and consumption. SamborChay watershed area with 74,830 hectares in the arid and semi-dry wines in Iran in Ardabil province is located. In order to determine suitable areas for harvesting runoff was used geographic information system GIS. For this purpose the use of concept maps suitable areas for water extraction based on the source level variable water volume obtained through AHP model was developed. After weighting to determine the parameters intensity rainfall in 30 minutes with 10 years return period, intensity rainfall in one hours with 2 years return period, average rainfall, NDVI, average slope, capacity infiltration, formation geology, and temperature their effect was assessment after appropriate and inappropriate areas were identified for harvesting runoff. The results indicate that sub basin at the northern of the area have a high potential for Production runoff with peak flow 7 to 21 (m3/s), concentration time 120 minutes, average temperature 13 C°, negative NDVI, high runoff 7 centimeters.

growing of population, development of agricultural and industrial activities were intensively increased the consumption of water resources, as results, the water quality and quantity have been decreased. Vast declining of fresh groundwater resources levels and infiltrations of surface runoffs and precipitations into groundwater, were decreased the runoffs dramatically and, as a consequence, the groundwater resources became as an important part of the water resources for drinking, industrial and agricultural demands in all over the country. Therefore, the importance of groundwater preservation, management and prevention of its contamination becomes as an inevitable task. One of the effective solutions to prevent the contamination of groundwater is to distinguish the vulnerable areas of the aquifer. In this study, DRASTIC, SINTACS and SI methods are used for assessment of vulnerability of the Ardabil plain aquifer. Using from these methods and with respect to the hydrological and hydrogeological characters of the study area, zoning of the vulnerability of aquifer to contamination is carried out and then susceptible areas to contamination was distinguished in each method. The measured nitrate concentrations in the area were used to validate each method. Correlation Index (CI) between vulnerability maps and nitrate amounts were calculated for exact and better comparing of these methods. Results showed that DRASTIC model has the highest CI, this means it is better than other methods for vulnerability assessment. According to the results of DRASTIC, 44.36% of the Ardabil plain aquifer area, located in the eastern and southern part of the plain, has low vulnerability and the rest parts including northern and western part of the plain has moderate vulnerability.

This study was performed to investigate the influence of different types of tourism in Aras Free Zone (AFZ). The tool of this research is questioner that data were collected by simple random sampling from 70 tourists and it have been analyzed using Structural Equation Modeling (SEM) approach. The results indicate that there is the correlation between ecotourism and historical tourism. In the other words, an increase in historical tourism increases the ecotourism and vice versa. For increase, historical tourism must increase satisfaction of historical attractions of "Chopan churches", "Caravanserai of KhwajaNazar". For increase, the ecotourism must increase satisfaction of the natural attractions of the "Aras", "Mill Ruins", Villages Ashtbyn", "Plain Gordian" and "Plain Aynalo". The increase of satisfaction of tourists of village "Ashtbyn", satisfaction of tourists from "Holy Muhammad Agha" increases. The only factor affecting the on trade tourism is the satisfaction of variety of goods or in other words to increase the satisfaction of trade tourism must increase the variety of goods. Therefore, restoration of historic and religious buildings and development projects, business tourism, natural and historical and policies encouraging exports and imports in Aras Free Zone is proposed

Evaluation of climate comfort and the suitable days for recreational walking in urban areas is a significant aspect of successful planning aimed at promoting the urban tourism industry. Khuzestan is a vast province in Iran with very high tourism potentials as well as climatic variety, and can be regarded as a tourism pole in Iran. This study aims to use the Equivalent Physiological Model for determining the number of climate comfort days in Khuzestan Province. To this end, the mean values of the daily data provided by eight synoptic meteorological stations during a ten year period (2000-2009) were used. Four meteorological factors were considered: dry air temperature, relative humidity, cloudiness, and wind velocity. The following cities were studied: Abadan, Ahvaz, Behbahan, Dezful, Iezeh, Masjed-e Soleiman, Ramhormoz, and Shustar. Upon feeding the mean data obtained for these cities to Rayman, the number of climatically suitable days for recreational walking in each city were determined. Upon taking into account the periods with negligible high- and low-temperature stresses, the output obtained from the computer model indicated that Iezeh with 168 climate comfort days was the most suitable city for accomodating tourists; followed by Masjed Soleiman (139 days), Ahvaz (130 days), Shushtar and Abadan (128 days), Behbahan (124 days), Ramhormoz (119 days), and Dezful (116 days). The results also showed that between late November and late March, Khuzestan Province would generally provide climatically favorable conditions for the visiting tourists.

The study of changes in water resources in each region is essential to manage water resources and using them. In this study, the goal is to evaluate the available water resources in the plain of Ardebil in terms of surface and subsurface resources based on four criteria including natural, hydrological, agricultural and humanitarian by using fuzzy network analysis. In order to assess better fuzzy network analysis evaluation, sub-criteria of population, industry condition, rainfall situation, the status of surface water (volume taken from the river) and groundwater (wells, springs and aqueducts status), the area under cultivation and the type of products in terms of water demand, slope and elevation are used. Dependencies among sub-criteria using DEMATEL fuzzy technique and according to experts are determined. Using the fuzzy network analysis all criteria and sub- criteria are weighed, and the maps for all sub-criteria, are generated in according to the weight obtained. Finally, the result map that is based on initial layers and weighted based on the fuzzy techniques is generated in GIS. The resulting map is identified the sensitivity of the study area in terms of potential water resources. The study area (Ardebil plain) is located in the northwest of Iran and is delimited by latitudes 38°05′ N and 38° 30′N and longitudes 48°15′ E and 48° 35′E. The average height is about 1360 meters from the sea level. It covers an area of about 820 km2 and is part of Qara Soo river basin. The low risk areas 11.13 % equivalent to 9200 hectares are located on the northern and a bit in west of the plain. The average risk areas 19.36 % equivalent to 15870 hectares are located in the north and west of plain. The high risk areas 21.3 % equivalent to 17510 hectares are located mostly in the central and upper parts of the plain. The vulnerable risk areas 31.9 % equivalent to 26220 hectares are located in the southern and central parts of the plain and finally the critical areas 16.1 % equivalent to 13250 hectares are scattered mostly in the south and east of the study area.

Density with increased population and disregarding social, economic, spatial-physical and environmental effects caused some problems that attracted the attention of urban planners and managements in metropolises such as Tehran. This problem is attention by urban planner and urban management. The proper framework of density (population density, high density, and land use density) at nine areas of 4 district of Tehran municipality seeks in this paper. And effect of density on earthquake vulnerability is study. This is an applied research; and research scrutiny methods are correlation, multivariate regression and fuzzy models. Data collected by documentary and survey methods. Research objectives include identifying density status (population, high, and land use) and discovering the relation between density level (population, high, and land use) and earthquake vulnerability and finally analyzing the effects of increased density (population, high, and land use) on earthquake vulnerability at municipality of Tehran (4 District). Research results show that it is necessary to consider three types of population, land use, and high densities in studying urban density. Moreover, fuzzy approach in urban density data normalization is one of the best approaches in urban vulnarability. In this regard, using fuzzy simple additive weighted method (FSAW) revealed that 7zone (density rank: 6.43), 8zone (density rank: 7.46), and 9zone (density rank: 8) at 4 district of Tehran obtained the lowest density rank; whereas, the highest mean density rank attributed to 6zone (density rank: 1.46) and 5zone (density rank: 2.48), respectively.

For tourism development, existing of tourist attractions is not enough, but developing of suitable tourist facilities is neccessory. So, according to the importance of tourist facilities in attracting tourists, especially to suburban places, the present study investigate the status of the tourist satisfaction of tourist facilities in Chak-Chak in Ardakan county. So, 106 number of tourists were selected in Norooz 2013 by Convenience sampling method. To gather data, library method, field method as well as tourist questionnaires were applied. Gathered data analyzed with descriptive (number, frequency, percentage, mean) and quantitative (T-Test, One-Way Anova, Pearson correlation) method. Regarding the first hypotheses, the findings indicated that tourists believe that the status of tourist facilities is very inappropriate in Chak-Chak and tourist satisfaction in all these three dimensions is low and very low; as a result, the first hypothesis was confirmed. The results indicated that the second hypothesis reject relatively, so that the total findings indicated that Chak-Chak tourists’ satisfaction is only significantly different in about religion variable. The results suggested that tourists’ satisfaction is not significantly different in all variables, except job position. To test the third hypothesis, the results of relationship analysis of tourists’ satisfaction and social-economic variables revealed that Chak-Chak tourists’ satisfaction has a significant relationship with all variables (gender, religion and job position) except age. So in general, the third hypothesis was relatively confirmed. In all, low level of tourist satisfaction indicate that the planning system ignored these places, whereas need more attention

General circulation models (GCMs) are an important tool in the assessment of climate change. These numerical coupled models represent various earth systems including the atmosphere, oceans, land surface and sea-ice and offer considerable potential for the study of climate change and variability. However, they remain relatively coarse in resolution and are unable to resolve significant subgrid scale features such as topography, clouds and land use. Bridging the gap between the resolution of climate models and regional and local scale processes represents a considerable problem for the impact assessment of climate change. Thus, considerable effort in the climate community has focussed on the development of techniques to bridge the gap, known as ‘downscaling’. In this study two statistical downscaling techniques (lars WG and SDSM) and Proportional Downscaling method have been sued , which are combination to TOPSIS approach.The result shows SDSM is more ability technique of downscaling. And climate change will reduce monthly rainfalls up to 39% and increase the temperatures up to 2 °C.

Uneven and unequal distribution of public land has been one of the consequences of libertine urban growth in the recent decades that has led to an unbalance in the distribution of urban public lands. This has had enormous implications, one of them being the lack of equal access to municipal services for citizens. Due to political and political developments in Ardabil during the recent decades this city achieved a massive physical growth so that this libertine physical growth has led to an unbalanced distribution of public land and caused forming a bipolar wealthy and deprived city. Accordingly this study aims at investigating and analyzing the public land distribution manner to evaluate the distribution of public utility and to grade and determine wealthy and deprived urban regions. This study employs descriptive-analytical method and essentially could have applied nature. To collect data the library method was used. To achieve study objectives two hypotheses were designed, in order to test the first one spatial autocorrelation analysis tools and the nearest neighbor index and to test the second one Kernel density function were used.
