Abstract: 

There are various factors that cause cantinous changes in the quality and quantity of natural resources which result in poor ranching, destructive flood, migration of villagers and nomads to large nearby cities and poverty of rural people. Identification of factors which are destructive to rangelands in Kermanshah Province was carried out to prevent destruction, to achieve optimal management and recognize priorities in planning. First of all, information and statistics concerning vegetation map and base map (from past to present) were obtained and analyzed. On the basis of Pabo Map and GIS, four different climatic regions of dry forest, warm semie-steppe. Cold semi-steppe and high mountainous were distinguished for Kermanshah Province. According to the survey conducted to explore the ecology of Kermanshah, index regions were identified using Pabo climatic Map. In any region, the vegetation of the range along with index of destruction of vegetation was studied. next step, questionnaires related to destructive factors to vegetation were filled by both experts and rural families and nomads and, then were assessed using the statistic method of regression and finally the frequency of different destructive factors to rangelands was calculated. The results indicated that in Kermanshah rangelands, changing the land use, the increase in the number of animals, and early grazing are the common factors of destruction respectively.
