【摘要】：社会经济与生态环境的协调发展是城市可持续和生态文明建设的必由之路。本文通过构建城市复合系统的生态—经济—社会协调发展评价指标体系,采用主成分分析、回归分析、模糊隶属度函数等方法建立城市复合系统协调发展评价模型。以西北地区重要的经济中心兰州市为例,定量估算兰州市2008-2012年生态、经济、社会各子系统综合发展水平及复合系统的协调发展度,进而探讨城市生态环境与社会经济的相互作用规律。结果表明:兰州市社会经济发展迅速,生态环境的发展相对滞后。生态—经济—社会复合系统的协调发展类型总体上属于中级协调水平,协调度的动态变化呈现波动上升趋势。说明在兰州市社会经济发展的同时,应通过优化产业结构、严守生态红线等措施,进一步提高生态环境质量。这将为兰州市及其他城市的生态文明建设和可持续发展提供可资借鉴的启示。
[Abstract]:The harmonious development of social economy and ecological environment is the only way to sustainable and ecological civilization construction. The evaluation model of coordinated development of urban complex system was established by principal component analysis, regression analysis and fuzzy membership function. Lanzhou, an important economic center in Northwest China, was taken as an example. The comprehensive development level of ecological, economic and social subsystems and the degree of coordinated development of the composite system are estimated quantitatively in Lanzhou from 2008 to 2012. The interaction between urban ecological environment and social economy is discussed. The results show that the social and economic development of Lanzhou City is rapid. The development of ecological environment is relatively lagging. The type of coordinated development of ecological-economic-social complex system belongs to the intermediate level of coordination on the whole. The dynamic change of coordination degree shows a rising trend of fluctuation. It shows that while the social and economic development of Lanzhou City, we should optimize the industrial structure, strictly observe the ecological red line and other measures. Further improving the quality of ecological environment will provide some enlightenment for the construction and sustainable development of ecological civilization in Lanzhou and other cities.
