Abstract

Catchment area of the Zagros forests, a sensitive ecosystem of the Zagros range. The Geographical Information System (GIS), and REMOTE SENSING techniques were used for the study. Firstly, land-sat data (TM imagery for 1990 and -f997) were used as inputs to prepare land-use maps for those years, using Idrisi software. Then, those land-use maps, together with "Optimal Spatial land-use maps" (based on sustainability, and prepared elsewhere using the system analysis method), were added to the GIS, using Arc/Info software, so as to build a data base. Subsequently, a process based model was created to compare existing land-uses with optimal one. Using this model and the Structured Query language (SQL) in the GIS the status of the land uses were mapped for 1990 and 1997, grouped in three categories: sustainable, non-sustainable, and conditionally sustainable. By comparing those maps, land-use changes from 1990 to 1997 were recorded. The results indicate that non-sustainable uses of land during this period have increased substantially due to, among other factors, the use of land for grazing purposes in places where land is suitable for commercial and protection forestry. Changing land uses to agriculture, where it is suitable for pastural uses was also observed. The research also indicates that the prevalence and increases of unsuitable land uses in the area have resulted in degradation of the environment and poverty for its inhabitants. Therefore, the research concludes with a strong recommendation for the preparation and implementation, by the relevant authorities, of an "Optimal spatial land-use. plan" for the area, so as to slow down further ecological and socio-economic degradation.
