The purpose of this study is to determine the potential of development in partial of Bandar-Abbas city, using degradation model and analytical capability of GIS. In this regard, firstly the study area was divided into 149 grid cells of 900 hectares (6×6 cm; on map of 1:50000 scale). Then, on the basis of degradation model, destruction coefficients have been calculated in all units of network. Ecological vulnerability has been calculated and classified by using biophysical maps. Then, in the next stage, destruction factors has been determined and calculated also physiological density has been calculated and in final, destruction coefficients have been calculated in all impact units. The results show that 130 units (87.23%) of network; need to be restoration and 18 units (12.07%) require protective actions. In the study area, areas with prone to develop has achieved very small percentage (0.67%). This paper suggested applying environmental educations for beneficiaries and attractive their collaborations, to set environmental management system in industrial factories, and to apply environmental capability evaluation and supervising on implement of state land use plans and EIA to prevent of the destruction.

Karami, Arash | Feghhi, Jahangir
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.

2012
Kowkabi, Lila | Ghadiri Masum, Mojtaba
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.

Rousta, Zahra | Monavvari, Seyed Masoud | Darvishi, Mahdi | Falahati, Fatemeh
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.

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.

Arbab, Parsa
This paper considers the spatial planning system in Russian Federation. Study of spatial planning system of Russia specifies three different stages from each other. The first phase consists of the sixteenth century until the early twentieth century. In this period, base of the spatial planning was formed and gradually developed during approximately 400 years. The next phase is devoted to Soviet domination. Under reliance on centralized state power and socialist ideas, spatial planning declines or can be implemented by specific and different opinions. In the third period, from creation of Russian Federation in the late twentieth century to today, territorial planning schemes are adopted at various levels of national, regional and local with emphasis on RF Urban Development Code. This era promises regular move that its perspective is provision of more appropriate context for more consistency, transparency and participation of different actors, implementation and efficiency.
