Dynamic Simulation on the Optimal Patterns of Land Use Change for the Farming- pastor al Zone in Nor th China
中国北方农牧交错带土地利用空间优化布局的动态模拟

Optimal land use planning, influenced by various factors, have been a frontier issue for LUCC studies in the world.Regarding CLUE-S model as the modeling framework,this paper designed a Land Use Change space optimizing simulation model and realized the optimal space distribution under six different scenarios.The findings are concluded that the difference of land use change is remarkable. Comparing optimal land use pattern scenario with the actuality, the cropland and grassland were concentrating. From the comparing of space distribution under different scenarios, at the space allocation process, the hotspot region was the Northeast, the Northwest and middle region. The Northeast focused on the forest land transformed to the cropland, middle region was the cropland to grassland, the Northwest was the space location changes between the cropland and grassland.
