区域空间管制约束下的建设用地动态变化分析——以常州市为例

DYNAMIC CHANGE ANALYSIS OF CONSTRUCTION LAND UNDER THE RESTRICTION OF REGIONAL SPACE CONTROL——TAKING CHANGZHOU CITY FOR EXAMPLE

在建设用地受到土地利用总体规划空间管制分区约束的背景下,参照"三界四区"的划定位置,从规模布局、结构变化和扩展方向等多方面出发,通过GIS空间分析技术和统计分析等方法,对比分析空间管制约束前后常州市建设用地的动态变化,此举有利于提高城市发展的规划管理效率。研究结果表明:(1)空间管制对建设用地的约束作用受时间和地域影响;(2)建设用地空间管制分区的划定在不同时期对不同建设用地类型产生的影响各异;(3)受允许建设区和有条件建设区空间分布的影响,常州市建设用地扩展方向由前期的东北-西南转变为后期的正北方向,有效缓解了"摊大饼"式盲目开发的趋势。

Under the background of construction land limited by zoning for regulating the constructive expansion in the general plan for land use,according to the location of ＂three boundaries and four areas＂,from the scale and layout,the structure changes and the extension direction of construction land,by GIS spatial analysis technology statistical analysis and other methods,contrastive analysis of various dynamic changes of construction land in Changzhou city before and after the restriction is beneficial to improve the planning and management efficiency of the urban development.The following conclusions can be drawn as：（1）The time and the region exerted an effect on the restraint degree of construction land by the spatial regulation.（2）The zoning for regulating the constructive expansion helped urban-rural construction land to make use of constructive expansion conditionally-permitted zone to realize the distribution adjust,and to limited the illegal occupancy of the construction land for transportation,water conservancy and other use.（3）Due to the spatial layout of the constructive expansion permitted zone and the constructive expansion conditionally-permitted zone,the expansion direction of construction land in Changzhou city changed from previous NE-SW to late due north,thus effectively relieving the trend of blind exploitation in the form of ＂standing pancake＂.
