Abstract

Mainly, Pastures of Iran are located in arid and semiarid regions. But according to local

meteorological studies, Band Ghora in Kashmar has semi-arid and cold climate. 3 to 4

times utilization of the grazing capacity of the pastures in this basin is based on the type

and percentage of of vegetation, slope and distance from water sources which led to the

destruction of the pasture. The aim of the study is improving the rangelands (Desertified

Rangelands or destroyed pastures), locating and upgrading the existing conditions with

regard to the capabilities and limitations and relying on the existing state of the pastures,

for improvement and reclaim operations such as: seeding, wet seeding, and grazing

management using GIS techniques. Using topographic maps 1:50000, digital

maps1:25000, images derived from Google Earth software as well as field visits of the

region, pasture land area was separated from other users. After that, the gradient maps,

floor height, susceptibility to erosion, the rainfall, vegetation type and size and

biological map of the region(bio-region) was prepared by putting digital maps in the

software Arc Map, ArcView environment, the locate map of the suitable projects for

improving pastures obtained. The result of the locate model of Kashmar's Bande Ghora,

represents approximately 12.12 square kilometers (23.94 percent) of the surface area of

the project of saw(ing), 2.7 kilometers (5.3 percent) of the project of seeding and 31.1

square kilometers (61.44 percent) of grazed watershed management project, is

appropriate.
