城市住宅用地扩展演化空间质量评价——以深圳市南山区为例

A CASE STUDY ON NANSHAN DISTRICT,SHENZHEN CITY:QUALITY EVALUATION ON EXPANSION EVOLUTION SPACE OF URBAN RESIDENTIAL LAND

以深圳市南山区的社区为单元,以扩展演化的住宅用地为研究对象,引入土地承载力变化指数、土地利用强度变化指数、土地利用结构变化指数与土地利用效益变化指数,运用层次分析法对城市住宅用地扩展演化的空间质量进行评估,以揭示城市住宅用地的空间利用状况,为合理配置城市住宅用地以及提高住宅用地的利用效率提供参考依据。研究表明,2009年至2012年期间,南山区住宅用地总体扩展演化速度较快,但扩展演化的空间质量不高,形成以"松坪山—安乐"为中心、"大学城—留仙"为次中心、质量值向外围逐级扩散的空间格局。

This paper,based on the Shenzhen＇s Nanshan community,adopts land load variable,land use intensity variable,land use structure variable and land use benefits variable to study the expansion evolution of residential land,and uses hierarchy analysis to evaluate its quality,aiming at disclosing the spatial use of urban residential land and at providing references for allocating urban residential land and improving land use efficiency. During 2009-2012,Nanshan district＇s had a rapid expansion rate in residential land with a lower quality in its spatial evolution,forming＂Songpingshan-Anle＂center and＂University City-Liuxian＂sub-center,quality value diminishing outward.
