福建省长汀县生态环境建设与经济发展的协调关系研究

以福建省长汀县为研究区域,建立生态和经济发展评价指标体系,基于功效函数模型和协调度模型,运用熵权法和多因素综合评价法,对该区域1985—2015年的生态建设与经济发展的协调状况进行分析。结果表明:1)功效函数模型结果表明,1985—2000年长汀县生态系统协调性呈上升趋势,1995和2000年分别达到中度和高度协调的水平,但2000年以后,生态系统协调性逐渐下降。1985—2015年经济系统协调性持续上升,经济发展协调性较好。2)协调度和协调发展度模型结果表明,长汀县生态与经济协调度在1985—2000年保持持续上升的状态,2001—2015年生态与经济协调度在整体转好的同时,也出现下行波动。3)长汀县生态系统和经济系统还存在人口压力、经济结构不合理、水土流失问题局部反弹等问题,生态环境治理和保护力度还有待加强。

Coordination relationship between ecological environment construction and economic development in Changting County,Fujian Province

Taking Changting County of Fujian Province in South China as an example,the evaluation index systems of ecological construction and economic development were established.The efficiency function and coordination degree models,combined with entropy method and multi-factor comprehensive evaluation method,were used to analyze the coordination of ecological construction and economic development from 1985 to 2015.The results showed that the coordination of ecosystem of Changting County displayed a linear upward trend from 1985 to 2000,and moderate and high levels of coordination were achieved in 1995 and 2000,respectively.However,the coordination of ecosystem was in decline since 2000.The coordination of economic system increased gradually since 1985,indicating that the economic development of Changting County was getting better and better.The results,derived from the coordination degree model,indicated that the coordination degree between the ecological and economic systems maintained a rising trend from 1985 to 2000 and from 2006 to 2010,respectively.However,there was a decline in coordination degree from 2001 to 2005 and from 2011 to 2015,respectively.In conclusion,there was still population pressure,irrational economic structure,recurrent soil erosion problems of the ecosystem and economic system in Changting County.
