Abstract:

In the process of urbanization, construction land plays an important role in the social and economic development, so construction land extensive use is related to the sustainable development of cities and towns. This paper, based on the features and factors of regional construction land use, establishes an evaluation system and employs to evaluate their construction land extensive use in Bodings cities and counties, and ranks their levels by using clustering analysis, and studies the spatial differentiation with GIS.

Key words: regional construction land, land extensive use, spatial differentiation, Baoding city

摘要：

在城镇化进程中，建设用地在社会经济发展中有着举足轻重的作用，因而建设用地是否节约集约利用关系到城镇的可持续发展。首先从区域建设用地的利用特点和影响因素出发，构建了区域建设用地节约集约利用评价体系。然后以保定各市县为例进行建设用地节约集约利用水平评价，最后运用聚类分析法对保定市各市县建设用地节约集约利用水平进行分级，同时进行GIS区域空间差异评价，并得出结论。
