武夷山市生态-经济-社会复合系统耦合协调发展研究

Research on Coupling Coordinated in Ecology-economy-society Composite System in Wuyishan City

运用复合系统理论选取福建省武夷山市作为研究对象,根据2005-2020年共16年的年鉴等公开数据,构建武夷山市生态-经济-社会复合系统评价指标体系,基于主成分分析法(PCA)确定指标权重,运用耦合协调度模型对武夷山市复合系统的耦合协调发展状况进行实证分析,并通过剪刀差法揭示生态与经济系统、生态与社会系统、经济与社会系统间的发展趋势变化差异。结果表明2005-2020年:①武夷山市生态系统、经济系统与社会系统综合效益指数均呈现增长态势;②武夷山市复合系统耦合协调度逐渐由弱转强,2005-2006年为缺乏协调阶段,2007-2010年为转换阶段,2011-2020年为系统协调阶段;③武夷山市复合系统内各系统间的发展趋势差异在波动中逐渐缩小。

Apply composite system theory and taking Wuyishan City as the research object, this paper constructed the evaluation index system of the ecological-economic-social complex system based on public data from 2005 to 2020. Firstly it used principal component analysis(PCA) to determine indicator weights,and then it used the coupling coordination model to empirically analyze the coupling coordination development status of the compound system in Wuyishan. It revealed the difference in development trends between ecological and economic systems, ecological and social systems, and economic and social systems through the method of scissors difference. The results showed that:(1) The comprehensive benefit index of the ecological system, economic system and social system of Wuyishan was showing an increasing trend;(2) The degree of coupling and coordination of the composite system has gradually changed from weak to strong, the period of 2005-2006 was the lack of coordination, the period of 2007-2010 was the transition stage, and the period of 2011-2020 was the system coordination stage;(3) The development trend difference among the various systems in the compound system of Wuyishan was gradually shrinking in the fluctuations.
