The land use pattern optimization can achieve efficient use of land resources. The land use pattern change and optimization of Xiheidaigou Watershed were studied in area of Soft Rock Region based on the land use status in different periods of map and topographic map data, through using linear programming method and cellular automata model, with the support of GIS technology. The results show that cultivated land and forest land increased to different extent, the forest land increased the most, the reduction magnitude of grassland area was larger, water body and construction land area had a different degree of reduction in the study period. The total area of cultivated land increased 20.67 hm2, forest area significantly increased to 1 501.89 hm2, grassland area decreased 157.68 hm2 after land use pattern optimization. The optimization makes the structural changes in land use significantly. So, in oder to achieve the purpose of watershed land use pattern, it is necessary to reduce soil erosion and to improve the comprehensive land productivity, which provides the basis for optimizing the regulation of land use pattern in arsenic sandstone areas.
