Fathizad, Hasan | Nohegar, Ahmad | Faramarzi, Marzban | Tazeh, Mahdi
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.

Jozi, Seyed Ali | Rezaian, Sahar | Irankhahi, Mehdi | Dabiri, Farahnaz
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.
