Overall planning of land use division is the key content of general land use planning revision.The regional Land use divisional comprehensive evaluation index system was built up by selecting 18 indexes from the following six fields of regional land use: economic development, social development,environment, land utilization situation and benefit.Comprehensive evaluation of land use extent taking towns as units in Zhangye City was made by using principal component analysis. Combined with clustering analysis, Zhangye City is divided into 4 land-use zones, and some countermeasures and advices for land-use strategy and policy were put forward. Furthermore, based on land suitability evaluation, Zhangye City was divided into 7 regulation zones using CIS spatial analysis,combined with data of DEM,slope,soil,temperature and precipitation, and the regulation measures were suggested for land utilizations in various zones.This study can provide scientific basis for regional land use planning, eco-environment protection and construction planning.
