基于能值的宁夏城市生命力指数集对分析

Energy-Vitality Index Analysis of the Urban Ecological Economy System of Cities in Ningxia

选择了银川、吴忠、石嘴山、固原、中卫等5个地级市作为研究对象,利用生命力指数框架,引入集对分析方法,综合能值指标,构建城市能值生命力指数,对比反映城市生态系统的相对健康状况,对宁夏生态系统健康状况进行了分析.结果表明,在被评价城市中银川、吴忠处于较高水平,中卫、固原处于中等水平,石嘴山处于较低水平.

City energy-vitality index is established by referring to the method of set pair analysis and some comprehensive energy index,which makes it possible to make comparison between the five cities in Ningxia,concerning their urban ecosystem health.The results shows that Yinchuan and Wuzhong are comparatively in a higher level,Zhongwei and Guyuan in a middle level while Shizuishan in a lower level.
