资源型城市生态化水平度量研究

在总结资源型城市生态系统特征的基础上,提出了资源型城市生态化度量的指标体系,分析了以往多指标体系的各种计算方法,采用主成分分析方法,以山西省大同市、内蒙古包头市、辽宁省鞍山市、甘肃省白银市、宁夏石嘴山市为例进行分析.结果表明,宁夏石嘴山市生态化水平在5个城市中处于中等水平,说明该市资源型工业正处于转型阶段,生态建设效益逐步显现,实现生态城市还需较长时间.

Ecological Assessment for the Resource-Based Cities

The characteristic of eco-system in the resource-based cities is analysed,a expert indictor system is setup to evaluate its ecological level.Some problems exist in the previous methods to compute indicator system,therefore the method of the principal component analysis is used.Then the cities of Datong,Baotou,Anshan,Baiyin and Shizuishan are evaluated.The result shows that the ecology level of Shizuishan is in the middle of the five cities,that means the extractive industry in Shizuishan are being at the stage of switching to a compound economy,the advantage of ecosystem construction is appearing more and more,but it will take a long time to be a ecological city.
