鄱阳湖生态经济区生态经济指数评价

Evaluation of ecological economy index in the poyang lake ecological economic zone

大力推进生态文明建设已成为全社会关注的焦点,衡量和评价区域生态经济发展状态是当前研究重点和难点。在借鉴经济增长生态指数及生态效率概念的基础上,运用层次分析法和专家咨询法,构建了包括社会发展、经济增长、生态建设、资源利用和环境保护等5个模块在内的生态经济指数评价指标体系和模型,并将其应用到鄱阳湖生态经济区。结果表明:(1)鄱阳湖生态经济区各县(市、区)生态经济指数差异明显,其中万年县的生态经济指数最高,达到55.74,在研究区中生态经济发展状态最优;瑞昌市的生态经济指数最低,只有28.65,即生态经济发展状态最差;(2)生态经济指数得分较高的经济较发达的县(市、区)在发展生态经济过程中应提高资源利用效率,加大环保力度,加强生态建设;其他地区应将经济增长的速度和质量相结合;(3)生态经济指数得分较低的县(市、区)在发展生态经济的过程中,应在保护环境的前提下,大力发展经济,提高经济发展水平和质量,并努力提高资源利用效率;(4)鄱阳湖生态经济区生态经济指数的总体得分也较低,只有38.37,处于较差水平,需从提高环境保护和资源利用水平入手。最后就生态经济指数评价体系构建方法和存在的问题进行了有益的探讨。

The society and related research fields were paying close attention to make great efforts to promote the construction level of ecological civilization in China. And measuring and evaluating the status of eco-economic development always was the focus and difficulty in current researches. Based on the methods of Analytic Hierarchy Process （AHP） and the concept of Eco-Factor of Economic Growth and Ecological Efficiency, combined with the fact of research area, the index system of Ecological Economy Index （EEI）, which includes social development, economic growth, ecological building, resource use and environmental protection, was built up to measure and evaluate the eco-economic system＇s development situation. The weights of all indicators in the EEI system were acquired from the method of expert consultation. All the methods were applied to assess the eco-economic development situation in Poyang Lake Ecological Economic Zone of Jiangxi Province. The results showed that： ⑴ The model of EEI could intuitively apply to reflect the eco-economic development situation and coordinate extent of the assessment units in the Poyang Lake Eco-economic Zone, which could provide some scientific guides on finding breakthrough point of evaluating eco-economic level for concerned management departments and policies making organizations. （2） There were distinct differences of Ecological Economy Index value between the counties, cities or districts. Wannian county was on the best situation with the highest EEI value （EEI=55.74）, and Ruichang city was found to be on the worst eco-economic development situation with the lowest EEI value （EEI=28.65）. （3） The developed counties （cities or districts） with high EEI value should improve resource use＇s efficiency, protect environment and strengthen ecological construction. The other areas should effectively combine the speed with the quality of economic growth in the process of eco-economic development. （4） The counties （cities or districts） with low EEI values should develop economics, improve the quality of economic growth, and increase the efficiency of resources use under the same time of protecting environment. （5） The overall score of the EEI value of Poyang Lake Ecological Economic Zone was on a lower level with 38.37, enhancing environmental protection and resources use level was the main measure in the future. At last, the constructing method of EEI system and some problems were discussed creatively.
