基于GIS的资源衰竭型城市聚集格局

运用数理统计和GIS空间分析对资源衰竭型城市的时空格局进行分析，进而探讨资源衰竭型城市形成的原因，以期为资源保护、城市规划及社会经济可持续发展提供参考。结果显示，资源衰竭型城市在类型结构上煤炭类比重最高，有色金属类次之，森林工业类比重最低；资源衰竭型城市的数量持续上涨，从区域上看主要集中在东北综合经济区，从省份上看集中于黑龙江、吉林、辽宁及内蒙古等省市区。相关性分析显示空间自相关特征突出，HH集聚和LL集聚主导，HH集聚分布于黑龙江、吉林和内蒙古，LL集聚分布于新疆和西藏等西部地区。Kernel密度分析采用180 km、300 km搜索半径，均表明东北、华北及中南地区为衰退型城市密集分布区域。

Concentrating pattern of resources-exhausted cities based on GIS

This paper studies the spatial and temporal pattern of resources-exhausted cities using mathematical statistics and GIS spatial analysis method, and discusses the causes of resources exhausted cities, intending to provide references in resources protection, urban planning, sustainable development of society and economy. In resources exhausted cities industrial structure, coal ranks top, then non ferrous metals, and then foresting. The number of resources exhausted cities is rising. They are most concentrating in the northeastern Chinas comprehensive economic zone, or the provinces of Heilongjiang, Jilin, Liaoning and Inner Mongolia. The global auto correlation shows certain positive correlation with spatial characteristics of dominating HH and LL clustering. HH clustering is spreading in Heilongjiang, Jilin and Inner Mongolia while LL in Xinjiang and Tibet. Kernel density analysis based on a search radius of 180 km and 300 km displays that resources exhausted cities are heavily concentrating in Northeast China, North China and Central China.
