重点生态功能区人口-经济-生态环境耦合协调发展探讨——以贵州省沿河县为例

Study on the Coupling and Coordination Development of Population-economic-ecological Environment in Key Ecological Function Areas:a Case of Yanhe County of Guizhou

【目的】定量分析出沿河县人口-经济-生态环境耦合协调发展现状,揭示出发展规律。【方法】综合考虑人口、经济、生态环境,建立一套重点生态功能区县域人口-经济-生态环境耦合协调发展评价指标体系。运用最小相对信息熵原理,将"层次分析法"与"熵权法"相结合,形成综合权重,对沿河县2010—2014年人口、经济和生态环境各项指标赋权,通过耦合协调度模型对原始数据进行定量化分析,得到耦合协调发展类型、发展趋势和未来发展方向。【结果】沿河县2010—2014年人口-经济-生态环境耦合协调度呈现出整体上升趋势,耦合协调发展类型分别为轻度失调、中度耦合协调、中度耦合协调、良性耦合协调和优质耦合协调,并由此提出耦合协调发展建议。【结论】评价结果为相关管理部门推进县域可持续发展提供理论支持,具有一定的应用价值。

[Purposes]Achieving the coordinated development of population, economy and ecological environment in the county is the important measure to implement the main function division, optimize the development pattern of land and space, and it is implementation of sustainable development strategy and realize the harmonious coexistence between man and nature in China. In order to quantitatively analyze the present situation of the coupling and harmonious development of population, economy and ecological environment, and reveal its development law in Yanhe county. [Methods] Comprehensive considered of study area＇ s population, economy, ecological environment, established a population-economic and ecological environment coupling coordinated development evaluation index system of key ecological function areas. Applied the minimum relative entropy principle, combined the analytic hierarchy process and entropy weight method to form a comprehensive weight, which can be applied to the population, economy and ecological environment index of Yanhe county from 2010 to 2014. According to the quantitative analysis of the original data, the coupling coordinated development type; development trend and future development direction are obtained. [Findings]The results shown that the coupling coordination degree of population, economy and ecological environment is showing an overall upward trend in Yanhe county from 2010 to 2014. And the coupling coordination development type was followed by mild disorder coupling, moderate coupling coordination, benign coupling coordination, high quality and high quality coupling coordination, and it put forward the suggestion of coupling coordination development. [Conclusions]The evaluation results will provide theoretical support for the relevant management departments to promote county sustainable development, which have certain application value.
