One of the basic and important fundament of sustainable development is Land use planning and use of appropriated with environmental characteristic and use correct of natural sources in the region and country. Ardabil province is one of the regions that its land use in some of its places is not appropriated with ecological potential، especially in the Lands which they are under cultivation. Therefore، this article have intend to analogy of land use now with ecological potential in the province. To prepare the map of land use، utilized the ETM and ASTER image sensor 2002 and so used from information layers in the linked organizations and ground survey. Analogy of ecological potential in the province is done in the GIS and according to method of Makhduom of course with slightly changes. We compared the ecological potential with land use of the province by overlying of different layers. The maps of region’s ecological potential were prepared with overlying of different layers by combine code in GIS. The Results show there is disagreement in the Dry farming areas with ecological potential. In other words، that is 37% fields of dry farming and 6. 7% cultivate in the country of Ardabil not agreement with ecological potential.

Before creating a free zone in the Qeshm Island، the indicators of development (social، economic، physical and environmental)، the lowest value was found.

The results suggest that the creation of social development indicators like education Qeshm، population and economic indicators such as the expansion of commercial markets، docks، customs، employment trends have been growing، despite the positive effects of creating، bottom of these crimes in the future urban structure of Qeshm is also ineffective acknowledges it is 50 percent of respondents to the insecurity situation in the city of Qeshm in the future will increase relative to the status Qeshm.

Nowadays، tourism development in rural capable tourism sample areas is one of the ways to save the villages from poverty، immigration، social and economical problems. So، the present study identified the environmental potential of the tourism sample area of Hajij Village through using a set of internal factors (strengths and weaknesses) and the external factors (opportunities and threats) and then، codified the tourism strategic plan in this area. Accordingly، the present study was an applied-developmental research with descriptive-analytic methodology. The data from questionnaires and field studies were survived in order to determine the four dimensions of SWOT technique. The research had a simple random sampling including tourism experts and scholars in the province. The findings of the study showed that Hajij Village had 11 strengths، 11 weaknesses، 12 opportunities، and 6 threats، which according to priority of these factors، T2، W3، O2، and S4 had the most scores. In addition، WO and SO strategies were located in the first and second priority for tourism planning. This assessment leaded to codifying of tourism development program of Hajij Village، which could help the improvement of tourism status in the tourism sample area of Hajij.

Many human activities due to the lack of consideration in environmental restrictions on the landscape ecology are influential and have severe environmental effects on natural ecosystems. This study was conducted to investigate the trend of changes in landscape ecology in Dehloran، Ilam. For developing maps of Land cover، and analyzing the changes، we used، respectively، the satellite images of (1985) TM and (2007) ETM + were applied and landscape metrics of class area، density of patches، number of patches، mean of patches size، edge density and mean of shape index Various class-level landscape pattern metrics were calculated using FRAGTATS، in order to analyze landscape fragmentation. The analysis of landscape metrics revealed that the extensive replacement of fair rangelands by agricultural lands، rangelands، residential areas and barren lands. The results showed that increase in the number of patches and decrease in the mean of the area size was an important indicator of significant index of degradation، and the process of degradation and destruction of landscape ecology was in an increase mood. Therefore the results necessitated paying attention to the quality of land use and cover in the region for to exploit natural resources appropriately and sustainably.

This study conducted to locate the landfill in the range of studies، in view of the most recent guidelines Environment Protection Organization of Iran as to the citation Article 12 of the law and article 23 executive bylaws Waste management In order to Reducing the damaging effects of environmental Activities، locations and Utilities Related with the Processing and disposal Ordinary wastes، Including all the places of burial and recycling Has been prepared. Using the screening regional method and GIS، the Legal-restricted areas as well as the fit regions for waste disposal at the regional scale reviewed and was specified. Then، fit regions in the local scale with regard the important parameters in this method and the weight of them have been Priorities. Three main natural conditions، land-use and economic factors was interference in this method. Then، based on the population growth rate and the amount of waste produced in a horizon of 20 years the area of land required for landfill in the Study area specified and Lands prone with an area of less than the amount determined is removed from the map of merit and was provision the final suitability maps include appropriate land-landfill by taking all the conditions and criteria of the environment protection organization of Iran was determined prone for landfill the 2770. 7 hectares at regional scales and 2105. 6 hectares of land at the local scale of the whole range of Studies.

Sustained development is achieved an overlapping is created between ecological، economical and social classes. The purpose of this research is to determine and measure the sustainability criteria and indices. An ecological approach has used in order to assess sustainability in watershed of Zeidasht1 to maintain a balance between three economical، social and ecosystem categories. Selected variables were obtained using common assessment and their value. In order to assess sustainability، watershed and range management projects monitoring and evaluation monitoring provided by president strategically supervising planning assistant and range and watershed management، forest organization (watershed management department، coordination and planning department) for Iran. As a whole، in rangeland ecological section، three criteria، nine indices and fourteen variables were evaluated. Final score for ecological one was 45 fall in to in moderate class and final score dedicated to social and economical issues about 32 that number of 2 is obtained in respect to 16 selective variables that also it categorized into moderate class. Eventually using matrices، score estimation and watershed validation table، watershed sustainability is determined. In respect to total Zeidasht watershed score، this watershed is categorized in too poor sustainability class.

Aim of this study is to identify suitable Urban Development spots with application of Environmental Criteria in Mahmoodabad Township. A series of criteria were identified by investigating various sources about the location of urban development to achieve the aim of this study. Then criteria were selected by Delphi questionnaire or survey experts. So 12 criteria and 30 subcriteria were selected for urban development site selection in Mahmoodabad Township. These remained criteria which can convert to maps were weighted with AHP method. Then criteria were converted to maps by Arc GIS software. After that the maps combined with a weighted linear combination by Arc GIS software and appropriate spots for urban development were chosen. Area of the biggest spot is 0/7 square kilometers and area of the next spot is 0/4 square kilometers. According to 26th article of executive regulations for new towns building، minimum area of a new city is 3 square kilometers. So، none of the spots are suitable for urban development. Results and the criteria which obtained in this research can be used as a guide in areas that have similar features (north coastal area of country) to Mahmoodabad Township.
