Reasonable exploitation from natural resources and organizing land use based on its ecological potentials, has an important role in the environmental management and preventing environmental degradation and having a sustainable development. Marvdasht town has been faced with immigration and the result of that is increasing population and changing land use. Regarding the climate and natural properties of the region especially the existence of an alluvial plain and permanent river, this region has great potentials for development. Therefore, for better organizing the land and agricultural activities, the ecological potential of the region and the land suitability of agricultural activities were considered to help sustainable development Planners This study for better performing the ecological model of Dr. Makhdoum in which the Weight and importance of parameters are not considered, has used the Fuzzy AHP and GIS and has identified and determined the suitable areas for agricultural activities within the area of Marvdasht County. The results of doing the Makhdoum ecological potential model with Fuzzy logic in Marvdasht County have showed the existence of all the seven categories of the model in the studied area. Also the results from the sensitivity analysis of the study shows that fuzzy base approaches can be used for increasing the accuracy in determining the land use of agricultural areas.

Today, the redaction of inequality resources and facilities is one of the most important criteria for sustainable development and social challenge in our country. One of the main necessities of the national sustainable development process is attention to regional characteristics by utilizing a collection of economical, social, and environmental indicators in order to optimally designate resources for various regions along with identifying these differences. This research intends to analyze the level of development in provinces of Iran. First, 13 economical, social and environmental indicators have been identified and related data has been gathered for 28 provinces in Iran. In order to provide a composite indicator the method of factor analysis has been utilized and composite indicators for the provinces have been calculated and categorized. According to this categorization Kohkiluye and Buyerahmad , Tehran and Semnan provinces have been ranked first to third, while Kordestan , Sistan and Baluchestan and Hamedan provinces are ranked among the last.

Industrial Revolution and its outcomes caused fast growth of cities and urbanization. Population and industries and overconcentration (especially metropolitans and big cities) and low quality of life on one hand and the limitations of horizontal growth on the other hand, put the strategy of building new towns as the agenda of the governments aiming to absorb population overflow and removing concentration from the metropolitans. Building new towns in Iran has begun since 1980s as a basic solution in the country's system of urbanism. Now with more than two decades of new towns activity, assessment of their Performance seems necessary. For this goal Andishe new town with population of 75596, the most populated new town within other new towns around Tehran-the country's biggest metropolitan is studied. In this research the data of Statistical Centre of Iran interviews with the authorities of New Towns Construction Company, field studies and questionnaires were used. SPSS software was used for data analysis. The findings show that Andishe new town has been successful in absorbing population overflow, gaining the inhabitants satisfaction and providing jobs.

Monitoring land use and land cover changes has an important role in planning and managing environment. Vegetative Zagros region, in terms of biodiversity and genetic reserves is very important. therefore, this research investigate the basic structure of Zagros vegetative landscape and then compare the northern and southern Zagros, in Kurdistan and kohgiloyeh and Boyer Ahmad provinces. For quantifying metrics related to the land use patches the analysis of the landscape metrics in combination with the gradient analysis method in GIS and FRAGSTATS was used. Results showed that the percentage of cover of sustainable land use for the province Kurdistan, is agriculture (45%), pasture (41%) and forest (12%) and for Kohgiluyeh and Boyer Ahmad, forest (45%), pasture (35%) and agriculture (12%), respectively. Generally, have Kurdistan province landscape includes the larger patches, and has simpler and more continuity, while Kohgiluyeh and Boyer Ahmad province goes toward fine grain structure.

Industrial revolution has had disadvantages despite its numerous advantages in all areas of human societies. One of the main problems our city planning is faced with these days which is caused by inappropriate special structure is the uncontrolled expansion and growth of cities. Urban sprawl growth is not limited to large cities but it has happened to small cities and middle cities as well. An example of such cities is Gonabad city and has had uncontrollably expansion throughout its life. The method of research in this study is an analytic-comparative and Shanon and Holdern entropy models are used together with ARC GIS software for preparing the maps and then the city growth pattern of Gonabad is analyzed at the end. The results that have been achieved from Shannon’s Entropy model, shows that physical development of Gonabad city have been reduce during the last ten years. Though this development has been irregular and uncompressed. Applying Holden’s model about Gonabad shows that during the years 1956-2006 around 51% of physical development has been a growth in population and 49% has been the horizontal and sprawl growth of the city that caused a reduction in population gross density and an increase in gross urban land per person.

Although Lorestan is a mountainous land in the middle bounds, of Zagros Mountains and has varied climate, watery rivers, new natural views, wetlands, waterfalls, lakes, forests, verdant pastures and its ancient civilization and history has excessive potential to attract tourists. And the it, hasn’t gained much success in affricating tourists until now present research seeks to identify development strategies in Lorestan. Descriptive – analyzing research method is applied purpose is studying tourism development in Lorestan Province by emphasis on existing limits in this province. By exploiting SWOT technique, strengths, weaknesses, opportunities and threats have been studied and analyzed. findings indicate that this province has 12 internal stregths, 15 internal weaknesses, 8external opportunities, 10 threat that have main effect on tourism performance in the area. In this research, statistical sample included 100 officers of lorestan province and by independent single society T-test, effect of these two environments in lorestan s tourism development has been analyzed and studied. Obtained research showed that both external and internal environments, have effects on tourism development of Lorestan province Finaly, solving strategies were extracted and graded. WO strategies situated in the first priority and So strategies situated the second priority in planning.

Perception of urban development process in urban planning and management of sustainable urban development is important. In this paper physical and spatial development of Varzaneh city is studied and, after recognition of its potentials and restricts with using Boolean model and overlaying in GIS and also calculation of requisite space for the added future population optimum strategies for future development is suggested. The method of the research is descriptive-analytic and method of data gathering is documental-library. In order for completion of data and monitoring urban development of Varzaneh, we have accomplished field study and group interview with Varzaneh people. The results of the research indicated that initially urban development of Varzaneh has been was self-growing and have happened around the center of the city, but because of existing agric cultural lands. It was impossible to develop the core and the new city along with the old city has been developed (they separate from each other by the river). In new developing plans direction of development is to the north. The results also signified that not only it’s not necessary to expand the city for future development even when population are threefold rather than now but also altitudinal development of city is possible due to the free lands, urban sprawl and one- floor buildings.

Hydro geomorphology is a branch of natural geography that deals with studying the shapes of ups-and-downs which are resulted from the function of the water and streams, especially the rivers. Recognizing and expressing the hydro geo morphological elements and their functions on the primary structural surface in the Kheir Abad basin and also providing some practical plans to recognize and manage the environment of the region are very important. This region is considered as a sub-region of the Zohreh River in Kohkiloyeh & Boyer Ahmad province and this river is a sub-basin of the Persian Gulf basin. The Kheir Abad River is located in the province of Kohkiloyeh & Boyer Ahmad in Gachsaran County (located in the northeastern part of the region) which is the only main streaming river of this region that originates from the various subordinate streams (often as the seasonal rivers) of the northern, northeastern, eastern and southern altitudes, and finally it reaches to the Zohreh River in Kohkiloyeh County. The followings are the purposes of the present study: analyzing the role of the hydro geo morph logical elements of the region regarding to capabilities and limitations of the natural prospects and landscapes, providing some suggestions and strategies and applications for the region in the framework of the capabilities and limitations to reasonably use the available resources. The present and applied method in this study includes a filed one that can be a suitable method to achieve investigative purposes and evaluate the hypotheses. Examining the physiographic, hydrological and hydro geo morphological elements, the geology, climatology, soil and flora and filed studies in the region with the help of determining and analyzing the influential elements in land-forming process, Geo morphological shapes which are present in the region and their developmental conditions reveal significant role of streams.

Industrialization and Urban sprawl together with population growth and increases in water consumption cause water pollution and destruction of natural resources quality; these are followed by reducing access to available resources such as drinking water. Every year a significant amount of urban waste water is discharged to water resources, while natural treatment is impossible. Cities in each level require different facilities and infrastructure. optimal resource utilization with appropriate site selection for water & wastewater facilities have an important role in water quality in the major cities and can control water pollution, so it has been considered to increase the quality of life in cities, also the neglect of attention to climate condition such as morphology, hydrology and topography cause negative impacts on urban environment. There are different models and methods to select suitable sites for facilities. They are specifically important in arid land where water resources have become increasingly scarce. One of the methods is zoning. In this paper satellite images have been used to locate facilities in a typical arid city in Iran, Shiraz. The large-scaled (landscape scale) land use maps has been prepared for Shiraz-Neiriz water basin, and the distinctive zones were determined base on arid and semi arid geo-hydro morphology. Then each zone were analyzed using large-scale land use, soil and topographic factors to determine adequate potential sites for facilities by regarding sustainable development and considering the cumulative effects of upstream area. At the end, some suggestions were determined to reduce urban environment pollution.

Natural sites with cultural value are one of the most important biological and cultural diversity reservoirs which have been conserved over several centuries by people. But in the present era, due to the lack of conservation criteria and also because of human activities, these sites have been threatened. The aim of this paper is to prioritize criteria for identification of conservation zones with cultural value. At first essential criteria for the aims of the survey were identified, and then assembled in a new structure. On the whole, 12 criteria were identified for the selection of protected areas, afterwards based on the Delphi method these criteria were screened out and the criteria landscapes with cultural values, intangible cultural assets, legal protection, tangible cultural assets, geographical region with natural value, social tendency, social institutions, unique natural landscape, geographical region with cultural value, specific species, conservation importance and social dependency; respectively, were considered important.
