摘要/Abstract

摘要： 目的测度分析区域森林生态-自然-经济-社会复合系统的耦合协调度，探究区域森林生态系统建设的驱动因子，为区域城市群的协调发展提供决策依据。方法基于1980—2020年长沙市森林生态-自然-经济-社会复合系统28个指标数据，运用熵值模型、耦合度模型、耦合协调度模型对区域森林生态-自然-经济-社会复合系统的耦合度与耦合协调度进行测度分析。结果 1980—2020年长沙市森林生态-自然-经济-社会复合系统的耦合度呈“倒U形”，整体呈现出上升趋势；森林生态系统与自然环境系统和社会系统之间的耦合协调度均呈逐年上升的“S形”趋势，与经济系统的耦合协调度呈先升后降再升的“N型”趋势，但2015年后各系统的耦合协调度上升趋势均有所放缓。结论 1980—2020年长沙市森林生态-自然-经济-社会复合系统以及各子系统之间的耦合协调度整体水平不高，以中度协调阶段为主，基本处于中度耦合协调向良好耦合协调的过渡时期，提升空间较大；森林生态-自然-社会-经济复合系统以及森林生态系统与自然环境系统、社会系统、经济系统的耦合协调度水平在1980—2020年均呈不同程度上升，但上升趋势趋缓。建议从构建优良的区域森林成长自然环境子系统、建立高质量可持续的经济发展子系统、搭建承载合理与绿色消费的社会子系统3方面提升区域森林生态系统耦合协调度，实现区域森林生态-自然-经济-社会复合系统的可持续发展。

Abstract: Objective This study aims to promote the coordinated and sustainable development of regional forest eco-nature-economic-society complex system. Method Based on 28 indexes data of the forest ecology-nature-economy-society complex system in Changsha City from 1980 to 2020, the coupling degree and coupling coordination degree of the regional forest ecology-nature-economy-society complex system were measured and analyzed by using entropy model, coupling degree model and coupling coordination degree model. Result From 1980 to 2020, the coupling degree of forest ecology-natural environment-economy-society complex system showed an "inverted U shape", with an overall upward trend. In Changsha City, the coupling coordination degree between forest ecosystem, natural environment system and social system showed an "S-shaped" increasing trend year by year, and the coupling coordination degree between forest ecosystem and economic system showed an "N-shaped" trend, with first increasing, then decreasing and then increasing again. However, after 2015, the rising trend of the coupling coordination degree of all systems slowed down. Conclusion From 1980 to 2020, the coupling coordination degree of the forest ecosystem-natural environment-economic-social complex system and its subsystems is not high. At present, it is mainly at the moderate coordination stage, basically in the transition period from moderate coupling coordination to high coupling coordination, and there is still a lot of room for improvement. From 1980 to 2020, the coupling coordination degree of forest ecosystem-natural environment-economy-society complex system and forest eco-system with natural environmental system, socio-cultural system and economic system in Changsha City has increased to different degrees, but the rising trend has slowed down. It is suggested that the coupling and coordination degree of regional forest ecosystem should be improved from three aspects: constructing fine natural environment subsystem for regional forest growth, establishing high-quality and sustainable economic development subsystem, and building social subsystem for supporting reasonable and green consumption, to realize the sustainable development of regional forest ecology-nature-economy-society complex system.
