摘    要:本文以区域生态经济系统为研究对象,根据区域生态经济系统的特征把它分成生态、经济和社会三个子系统(简写为EES系统),建立了关于区域生态经济系统协调度评价的指标范畴;同时依据协同发展原理构建了协调度评价的功效函数、协调度函数和协调等级理论,并以湖南省益阳市资阳区为例,从系统指标体系中共筛选出21个代表性指标对该系统的协调度进行了研究分析,结果表明资阳区在1995-2001年间,系统的协调度呈现下降趋势,表现为弱度协调状态,协调等级为6级,生态子系统的协调度是降低趋势,经济子系统的协调度是上升趋势,社会子系统协调度在平缓中略降,生态子系统协调度降低是导致整个系统协调度降低的根本原因,可见在资阳区发展经济与保护环境的矛盾比较突出。

关 键 词:生态-经济-社会复合系统  协调度  协调等级  资阳区

Abstract:The paper took region eco-economic system as studied object, and divided region eco-economic system into three sub-system that are ecology sub-system, economy sub-system and society sub-system according to its character(Abbreviated EES system), and constituted the appraisement index category of EES system. The paper constituted efficacy function, function of harmony degree and rank of harmony degree about EES system by Synergistic Theory, and did a case of Ziyang Section, Yiyang City of Hunan Province(Abbreviated ZYH), from EES system , chose 21 index that could typify the development actuality of ZYH, and analyzed the harmony degree of ZYH. The result make know that harmony degree of ZYH is taking on decline trend and being weak harmony state from 1995 to 2002, the rank of harmony degree is 6 grade; the harmony degree of ecology sub-system is declined, the harmony degree of economy sub-system is ascended, the harmony degree of society sub-system is declined slow, therefore its influence is very limited to EES system. The decline of harmony degree of all region eco-economic system of ZYH is caused by ecology sub-system, so the contradiction between economy development and environment protection is very highlight.
Keywords:Ecology-Economy-Society System  harmony degree  rank of harmony degree  Ziyang Section
