基于绿色城镇化的视角,并结合城市生态承栽力理论,从生态承载弹力和生态承载压力两个子系统出发,构建我国城市生态承载力的综合评价指标体系。进而以安徽省为例,通过构建城市生态承栽指数、压力指数及生态承载力综合指数等多维度模型来对其2015年的16个地级市的生态承栽力状况进行了多维测度,并描绘其区域空间差异分布。分析结果显示:安徽省16个地市中仅黄山、池州、滁州三市处于生态承载的低负荷阶段;宣城、安庆及六安市三市的生态承栽力承压基本持平;其余10省的生态承载力综合指数均大于1,处在一个高负荷的生态承载阶段。
This paper established a comprehensive evaluation index system for China's urban ecological carrying capacity from the perspective of green urbanization and based on the theory of urban ecological carrying capacity, including the two subsystems of ecological carrying elasticity and pressure. Taking Anhui Province as an example and by establishing urban ecological carrying index, pressure index, comprehensive index of ecological carrying capacity and other multidimensional models, this paper measured the ecological carrying capacity of 16 prefecture level cities of Anhui in 2015, and investigated the spatial differences among them. Research results show that., only 3 cities- Huangshan, Chizhou and Chuzhou-were in underload stage, Xuancheng, Anqing and Lu' an in normal stage, and the other 10 cities in overload stage, with comprehensive index of ecological carrying capacity being higher than 1.
