Abstract

 The purpose of this study was identifying rangeland DEVELOPMENT and RESTORATION operations targets. This study was conducted in Hossein Abad Bazoft basin with 7162 ha area, located in south east of Farsan County, Chaharmahal and Bakhtiari Province, Iran. The basin has various land uses including rangeland, forest, irrigated farm and garden, dry farm, residential area and rock mass. In this study, during land surveying process, ecological carrying capacity was first calculated for the rangelands and forests ecosystem. After capability evaluation, with regard to keeping the current land use and avoiding from more land degradation, RESTORATION programs were proposed. In this regard, required data layers including altitudinal classes, slope classes, aspect classes, rangeland condition and trend, climate, soil hydrologic groups, depth and texture of the soil, geology and geomorphology were overlaid using GIS 9.3 by intersect method, and 280 homogenous units were resulted. The results of homogenous unit characteristics assessment showed that the region fell respectively in the categories 1, 3, 6, 3 and 4 for conservation, rangeland, forest, agriculture and unauthorized agriculture capabilities.Finally, according to the characteristics of the achieved capabilities and defining required criteria to propose each executive program, we proposed the location and the kind of the executable RESTORATION programs such as exclosure, hill seeding, converting the inefficient dry farms to forage plants cultivation and in forest quantitative and qualitative regeneration.
