不同协调函数对生态-经济-社会复合系统协调度影响分析——以湖南省益阳市资阳区为例

本研究借助协调度函数分析了区域生态经济系统的协调度,形成区域生态经济系统评价的基本理论体系,包括功效函数、协调函数、协调等级和评价指标体系。并采用几何平均法、加权平均法、方差法和变异系数法建立了协调函数,综合分析了4种协调函数的协调等级,并以湖南省益阳市资阳区为例进行实证分析与验证,结果表明理论分析与实际情况基本一致,该理论具有一定科学性和可行性。

Influence of different harmony functions on the harmony degree of ecology-economy-society system-A case study from Ziyang District, Yiyang City, Hunan Province

The harmony degree of the ecology-economy-society system was analyzed by using the harmony function and a series of basic theory of evaluating the ecology-economy-society system were established including the efficacy function, harmony function, rank of harmony degree and evaluation index. Four kinds of method were constituted about the harmony function, being the geo-mean method, weighted mean method, variation method and coefficient of variation method, at the same time the rank of-harmony degree was analyzed completely. Finally, the harmony theory was validated by a case study of Ziyang District, Yiyang City, Hunan Province. The result is identical with its fact in the way, so the harmony theory is scientific and feasible.
