Land use planning is a science that determines the optimum use of land, regarding to the land ecological characteristics and socio-economic conditions. In land use planning of Ghurichai watershed with area of 24039 ha, six information layer including elevation classes, slope, aspect, soil type, vegetation type and density were combined using dual method and the final map of environmental unites were obtained. In this processes 1921 micro ecosystems or environmental units were distinguished in GIS environment using Arc map software. Ecological potential evaluation for agriculture, rangeland use, forestry, extensive and intensive tourism, aquaculture, rural and urban development and conservation were assessed for each unit. Finally 12.3 percent of the area was allocated to agriculture and rangeland use, 0.4 percent to extensive tourism, 52.5 percent to forestry, 1.1 percent to aquaculture, 1.7 percent to rural and urban development and 32 percent were allocated to conservation. Most of the area was allocated for forestry use, due to high capability and potential of this area for forestry. Therefore it is necessary to implement some basic practices in this area to prevent forest degradation in order to avoid land degradation and to have sustainable utilization of the mentioned watershed resources. In order to prevent irregular use of the forest, some alternative options have to be suggested for the stockholders of the watershed, not to endanger the socio-economic life of inhabitants. Therefore According to the result of the study, two new land use including aquaculture and extensive tourism suggested for this area.
