Assessment of Land Degradation and Desertification with Use of IMDPA Model (Case Study; Chah-hashm Plain, Iran)

摘要: Objective: More than 75 percent of Iran is located in arid and semi-arid then land degradation desertification are one the crises ecological. We require a proper understanding causes processes to control huge phenomenon on global regional situation. Because southeast assessment very importance for planning project. Methods: In this study, using GIS techniques assess with IMDPA model 27.020 Ha Chah-hashm Plain. Results: Result show vegetation criteria (2.97) more effective climate (2.68) other hand aridity index (3.92) most continuing drought (1.6) less area. indicated intensity high class 2.82 numerical value. area some limitations such as lack rainfall, temperatures, evaporation, instability sensitivity soil erosion natural limits cannot be but improved irrigation methods, education extension service optimization use agricultural can move improve situation assist slowing
