The purpose of the paper is to set up a system of land use main function zoning,to provide basis for the regulation and to control the regional land use.Based on the conception model of combination of coordinate and attribute,this paper bring spatial coordinate,spatial relationship and attribute features into the unitive model of spatial computation.A system of main function zoning of regional land use is established and the 19 townships of Yubei District in Chongqing City are divided into 4 land use main functional zones.(1) Northern New District,Shuangfengqiao Street and Huixing Street belong to optimized development zone;(2) Longshan Street,Longxi Street,Longta Street,Yuelai Street and Shuanglonghu Street belong to important development zones;(3) Xinglong Town,Gulu Town,Dawan Town,Longxing Town,Yufeng-shan Town and Tongjing Town belong to moderate development zones;(4) Luoqi Town,Shichuan Town,Muer Town,Dasheng Town,Cizhu Town belong to control development zones.The result of spatial cluster analysis simultaneously reflected the characteristics of spatial location and attributes,meanwhile spatial cluster analysis could reflect the spatial proximity which can make the clustering results more objective.
