Acknowledge of coverage amount of country present condition in a watershed is unavoidable necessity for optimal and permanent development and utilization. In this research, Fashand watersheds in northern-east of Hashtgerd city choose. First have recognized independent variables to prediction of country power. Then with assistant of field studies and Geographic Information Systems (GIS) prepared various weight maps as information layers and classified and composed them using coverage index. In next stage, coverage agriculture power predicting map with present country conditions map and calculate correlation matrix. Result showed that predicted area with much week and week talent include intermediate rangelands with 19.47 percent coverage. And areas with medium talent for agriculture intensity have 0.3 percent stratification. And good and very good predicted areas for agriculture intensity include 39.7 percent, good rangelands 2 percent, poor rangelands intensity 29 percent. Regretfully 994 Hectare of very good agriculture rascals have specialize to civic areas that shows having no comprehensive programs in this base. Prediction shows that 9259 Hectare of rascals with 52.17 percent of total areas include very good agriculture lands and medium, week and very week areas include less than 23 percent of total Fashand area. At the end, suggest that programmers and propagators present a model for each area regard to ecological power of area and present intensities conditions, to have in mind area with optimal utilization and suitable intensity use.
