Land Use and Land Cover Change Modeling in Zhangye City

Land use and land cover change is the main reason of global change, and it relates to sustainable development closely. We apply the advanced model CLUE-S to simulate land use and land cover change in Zhangye city from 2000 to 2020. Land use type is divided into 6 types, including field, woodland, grassland, water area, town, unused land. Using regression method, we choose 7 kinds of driving factors that make important contribution to land use and land cover change in this area. It includes distance to city, distance to river, distance to road, population density, altitude, slope and aspect. The simulation result shows that the area of woodland, grassland, water and down increases. However, the area of field and unused land decreases.
