Abstract

The aim of this study uses GIS techniques for programs biological management in arid areas of the Sheikh-Bahaei watershed. The study area (9091.34) is located in northern Isfahan. All parts of the watershed research studies, such as physiographic units, hydrology, geology, vegetation, geomorphology, soil science, land resources and erosion are investigated. Various methods for determining the above units are used in the study although some were approved and others declined. Single components were identified in the assessment of land resources and land capability [physiographic units]. Some factors like slope and its direction, the presence or absence of rock outcrops, vegetation, elevation difference, geomorphologic units and geological formations are divided into land units. Based on the percentage of gravel soil depth, density, coverage, and limiting factors of soil type; field observations of all the components are divided into land units by soil studies classes, including all the factors slope, elevation difference, slope types, soil horizons, soil depth, bedrock depth, and methods of correction factors and nonreversible modification for examination. Collection management practices in this area include planting, management and grazed systems. The implementation of various biological and protective operations totaling $298,931.62 led to an additional level of financial strength which increases farmers’ annual basis. A significant number of livestock, an excess supply of employment and reduced pressure on the rangeland livestock area will be examined.
