摘　　要：城市土地集约节约利用是解决经济社会发展中土地供需矛盾的主要途径。利用ArcGIS 10.2软件的空间统计功能与地统计模块,得到2018年全国273个参评地级城市的土地集约节约利用综合指数的空间分布特征图与变化趋向图,并分析探讨其空间变异特征。研究表明:1)中国273个地级参评城市土地集约利用点中心在河南省信阳市,而各省的中心点大多在其省会城市,少数在其余城市;2)试验区地级城市土地集约利用整体扩散方向特征为由西南向东北,各类别的地理分布的扩散方向特征基本遵循此规则;3)城市集约可发展的潜力也是越远离沿海城市越高;4)ArcGIS能够对城市土地节约集约利用的空间分布得到直观结果,且能够实现属性数据与空间属性数据的关联。Intensive and economical utilization of urban land is the main way to solve the contradiction between land supply and demand in the economic and social development.Using the spatial statistical function and land statistical module of ArcGIS 10.2 software,the spatial distribution characteristic map and change trend map of land intensive and economical utilization comprehensive index of 273 participating prefecture level cities in 2018 are obtained,and the spatial variation characteristics are analyzed and discussed.The results show that:(1)the centers of 273 participating cities are in Xinyang City,Henan Province,while the centers of each province are mostly in its capital cities,a few in other cities;(2)the overall diffusion direction of land intensive use in the pilot area is from southwest to northeast,and the diffusion direction of various geographical distribution basically follows this rule;(3)urban intensive use can be The development potential is also higher away from coastal cities;(4)ArcGIS can get intuitive results on the spatial distribution of urban land conservation and intensive use,and can realize the correlation between attribute data and spatial attribute data.
