摘要
基于珠三角城市群社会经济和土地利用数据,研究城市-区域尺度土地集约利用程度现状和特征等问题。结果表明,珠三角城市整体土地集约利用程度提升,但集约利用程度存在显著的时间、空间差异。从时间的角度看,珠三角土地利用集约水平呈现缓慢增长的趋势,区域内部差异逐渐降低。从空间的角度看,珠三角土地利用可以分为高度集约城市、中度集约城市和低度集约城市三种类型,集约水平呈现从核心区向外围区、边缘区不断衰减的空间特征。珠三角未来发展应该转变土地管理机制,创新土地市场,提高建设用地的配置效率,从而提高土地集约利用程度,促进经济、社会和环境可持续发展。
Over the last several decades,intensive land use and sustainable development are becoming increasingly important tools to further the growth of China's urban regions. Current literature pays attention upon the methods,principles,and practices of intensive land use,especially in developing urban regions,in order to better understand sustainable development. This empirical study examines the extent and features of regional land use intensity of the Pearl River Delta( PRD) urban agglomeration by using time- series data from 2002 to 2010 based on the analytic hierarchy process( AHP) method. The results of the analysis indicate the followings:( 1) level of land use intensity differs from temporal land spatial location both on the city and regional scale;( 2) the degree of land use intensity of core areas in the PRD urban agglomeration is higher than that of the peripheral areas. Finally,we provide further suggestions concerning land use intensity in the PRD.
