基于GIS的中心城区空间管制区划方法研究——以岚皋县城中心城区为例

空间管制区划是规划转型期中有别于传统用地布局规划的一种政策性空间管理手段,而非简单的用地评价分区,其对我国城市总体规划由技术型向政策型转型具有重要的现实意义。以岚皋县城中心城区为例,通过构建空间管制区划评价指标体系,运用GIS技术得到土地建设适宜性分区,并在此基础上以"规划主干路网和中观用地格局"为核心,结合地形条件进行区划归并和修正,将中心城区划分为禁建区、限建区,以及高强度、中强度、低强度三类适建区,并单独划出已建区,同时,在各分区之间划出一定宽度的缓冲区,从而得到最终的区划方案。

Study On Method Of Spatial Governance Zoning In Downtown Area Based On GIS:Langao Example

Spatial governance zoning is a kind of policy spatial management in transition of planning,which is different from traditional blueprint-plan,rather than simple land evaluation division.It plays an important role in the transition of master plan from technology-based plan to policy-based plan.The paper puts Langao county as an example,sets up an evaluation indices system,and specifies land suitability based on GIS analysis,then merges and amends the zoning on the basis of trunk road network in plan,concept land use pattern in plan,and terrain,finally,divides downtown area into five types: construction forbidden area,construction limited area,and high,medium,and low construction suitable area,then specifies built-up area and buffer area between different divisions separately,
