Abstract

Ranges have long been used so far. In recent decades, population growth, increasing livestock numbers and lack of proper principles of pasture utilization has caused great pressure on pastures. As a result of the degradation of rangelands and regress to the disappointing stacks go. Degradation of pasture management is an important part of the activities. This applies to vegetation restoration operations through a combination of biological and mechanical methods possible. Enormous annual cost of these operations is the only country in the watershed. One of the most important and most top performing sectors, positioning them correctly is an important contribution to the success of the operation. Therefore, in this research to prioritize the proper places of pasture biological practice pass seeding operation Ghushchi Urmia TOPSIS method was used in ARC-GIS software environment. This map was produced in the first stage of the regional homogeneity. Secondly, the 9 criteria that influence the location and biological practice seeding operations were determined. Thirdly, the criteria were weighted. Then the TOPSIS method over measures was implemented. Finally, the final map of prioritize the right places and biological practice seeding operations were prepared. The results of this study indicate that homogeneous units 29 with 0.659 suitable for seeding operations, homogeneous units 10 with 0.679 suitable for biological practice operations.
