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.

Increasing technology and population in the two recent decades have led to destructing nature and changing its land cover. Remote sensing is one of those new technologies which provide accessibility for managing earth resources. the dynamic information of remote sensing can play an effective role for monitoring and analysis of land use change using digital change detection techniques. Method used for the rate of development of remote sensing, is on the basis geometric correction, spatial and spectral enhancement of available satellite images with regard to the maximum likelihood supervised classification and post classification method. At first we produced land use maps by using the satellite images of landsat. The results of this study are, in addition to the impacts of environmental sensitivity visualization development trend based on the visual display, calculate of the land use changes together in developed area and production of digital map changes, to support land management.

Migration and its consequences have been discussed as one of the major social issues in recent years in Iran. In all official censuses, East Azerbaijan Province has the most migrants and executive managers are faced with serious challenges. This paper has analyzed migration behavior in inside and outside of East Azerbaijan province in recent three decades. Research method is descriptive and analytical and the statistic society is East Azerbaijan province. The results show that there is a populous link between East Azerbaijan province with neighbor provinces and Tehran. The majority of whom arrive to the province are from Tehran, West Azerbaijan, Kurdistan and Khuzestan provinces that include more than 70% of migrants and the main sources for immigrants from the province are Tehran, West Azerbaijan, Qom, Ardebil and Khuzestan provinces that include more than 80%. Also the main sources of who migrate inside the province are Tabriz, Maragheh, Ahar and Marand cities that include more than 50% of total immigrants and the major destination for migrants are Tabriz, Maragheh, Marand and Bonab cities that include more than 66% of them. Result's analyses show that there is not a systematic population replacement and that population exchanging occurs with cities that have more facilities and offer better services.

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.

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.

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.
