| 摘 要： | 城市生态系统的评价对于社会经济的发展、城市的生态规划具有重要意义.利用主成分分析法对安徽省17个地级市的城市生态系统进行评价,依据城市生态系统的特点及数据的可获得性,从社会、经济、资源环境方面构建了城市生态系统评价指标体系.结果表明17个城市之间生态系统状况存在着一定的差异,合肥及沿江地区城市生态系统发展较好,两淮地区、蚌埠、安庆等工业城市次之,皖南地区及皖北宿州等地城市生态系统发展欠佳.

| Abstract: | Sustainable land use is the foundation of sustainable social and economic development in a region, measuring whether the regional land - use is sustainable or not, we thus need to evaluate the urban land use system scientific quantitatively. The land use dynamic attitude, information entropy, balanced degree and concentration of such indicators are used to research land use quantity and structure change of Fuzhou. Then the index system from three aspects of the land utilization of social benefit, economic benefit and ecological efficiency is set up, and the su＇stainability of land use in Fuzhou by method of integrated weighting is evaluated. The result shows that the sustainable evaluation value of land utilization in Fuzhou is in increasing trend during the study period. |
