摘要:
以三峡工程主体所在的重庆市三峡库区22个区县为评价单元,从生态环境、生态经济、生态生活、生态制度、生态文化5个方面选取20项指标建立生态文明评价指标体系,通过熵权法和多因子加权法计算各区县生态文明指数,并运用ArcGIS 10.5软件的自然断点分级法对各区县生态文明发展程度进行空间分级及可视化,分析近10年来重庆市三峡库区生态文明发展水平的时空演化特征,初步揭示库区各区县在生态保护与经济社会发展中的矛盾和短板.研究发现:① 2006-2016年,重庆市三峡库区各区县生态文明发展水平整体提高,但各区县增速差距较大.生态文明指数均值由2006年的0.135增长到2016年的0.413,增幅为205.93%,其中增长幅度最大的江北增幅为370.53%,最小的武隆增幅为150.49%.② 2006-2016年,重庆市三峡库区生态文明发展水平高低集聚格局基本稳定,但以生态经济为主导优势的新型高值区正在形成.重庆市三峡库区生态文明发展水平高值区主要分布在以巫溪、巫山为集聚中心的库区东北部,以石柱、武隆为集聚中心的库区东南部,以及正在形成的以渝中为中心的主城区;而低值区则主要分布在长江以北的大片区域.

Abstract:
The Three Gorges Reservoir Area is an important ecological functional area and a typical ecologically fragile area in China. It integrates large cities, large countryside and large reservoir areas. It occupies a special and important position in the regional development pattern of China. The level of ecological civilization construction in the Three Gorges Reservoir Area is not only directly related to the ecological security and follow-up development of the reservoir area, but also to the sustainable development of the middle and lower reaches of the Yangtze River. Taking 22 districts and counties in Chongqing Three Gorges Reservoir area where the main body of the Three Gorges Project is located as the evaluation unit, this paper selects 20 indicators from five aspects of ecological environment, ecological economy, ecological life, ecological system and ecological culture to establish an evaluation index system of ecological civilization. The entropy weight method and the multi-factor weight method are employed to calculate the index of ecological civilization of each district and county, and Jenks natural breaks optimization of ArcGIS 10.5 software is used to realize classification and visualization of the development of ecological civilization in different districts and counties for the analysis of the spatial and temporal evolution characteristics of the development level of ecological civilization in Chongqing Three Gorges Reservoir in the 10 years from 2006 to 2016. Preliminarily results are achieved for revealing the contradictions and shortcomings of ecological protection and economic and social development in different districts and counties in the reservoir area. The development level of ecological civilization in all districts and counties in the Three Gorges Reservoir Area of Chongqing in the 10 years improved as a whole, increasing from 0.135 in 2006 to 0.413 in 2016, with an average increase of 205.93%; but there was a big gap in the growth rate among various districts/counties. The increase was the biggest in Jangbei District 370.53% and the smallest in Wulong 150.49%. From 2006 to 2016, the pattern of high and low concentration of ecological civilization development level in Chongqing Three Gorges Reservoir Area was basically stable, but a new type of high-value area with ecological economy as the dominant advantage was taking shape. The high-value areas of ecological civilization development in the Three Gorges Reservoir Area of Chongqing were found to be distributed mainly in the northeast of the Wuxi and Wushan reservoir areas, the southeast of the reservoir area with Shizhu and Wulong as the gathering centers, and the forming main urban area with Yuzhong as the center, while the low-value areas in the vast area north of the Yangtze River.
