Abstract:

This paper, aiming at land utilization partition methods and providing references for general land utilization planning, takes districts and counties as basic evaluation units, selects ten indexes including resources, environment, society, economy, land utilization structure, etc., applies principal component analysis to reduce variable dimension and give scores, and uses cluster analysis to achieve land utilization partition. The results indicate that Taiyuan city is divided into two hierarch I regions and five hierarch II regions, each given corresponding land controls. The paper provides a useful tool to regional land utilization partition and controls.

摘要：

研究目的：探讨土地利用分区技术方法，为土地利用总体规划提供编制依据。研究方法：以区县为评价单元，筛选资源环境、社会经济、土地利用结构等10个评价指标，采用主成分分析实现指标降维并综合评分，利用聚类分析实现土地利用分区。研究结果：太原市可划分为2个一级区及5个二级区，根据区内特点提出了相应的土地调控举措，是土地利用总体规划分区调控的有力工具。
