摘要
【目的】对长江经济带山水林田湖草生命共同体的健康状况进行诊断,并对它的耦合协调关系进行分析,为它的健康管理及长江经济带的生态治理提供科学依据。【方法】基于构建的长江经济带山水林田湖草生命共同体健康诊断指标体系,使用正态云模型进行有关健康诊断,并运用耦合协调模型对山、水、林、田、湖、草子系统间的耦合协调关系进行分析。【结果】(1)2000—2018年长江经济带山水林田湖草生命共同体健康等级整体上呈上升趋势;在空间分布上,山水林田湖草生命共同体健康等级较低的省(直辖市)位于长江经济带的上游和下游区域,中游区域是整个长江经济带山水林田湖草生命共同体健康状况最好的区域。(2)长江经济带山、水、林、田、湖、草子系统按健康等级由高到低进行排序,依次为:田子系统、水子系统、山子系统、草子系统、湖子系统、林子系统。(3)在由长江经济带山、水、林、田、湖、草子系统构成的46种系统组合中,90%以上的系统组合的耦合度高于0.8,处于高水平耦合阶段;但约98%的系统组合协调度为0.3~<0.5,处于轻度失调阶段。(4)林业单产、森林蓄积量、湖泊面积、人均水产品、渔业总产值等指标是长江经济带山水林田湖草生命共同体健康的主要驱动因子。【结论】虽然2000—2018年长江经济带山水林田湖草生命共同体的耦合性和协调性的发展阶段水平差异较大,但两者都有向更高水平阶段发展的趋势。
[Purposes]The ecological management of mountain,water,forest,field,lake,and grass in the Yangtze River Economic Zone(YREZ)is a century-old plan for the sustainable development.[Methods]The mountain-water-forest-field-lake-grass(MWFFLG)life community in the YREZ was taken as the research object,based on the construction of the health diagnosis system of the MWFFLG life community,the Normal Cloud Model were used to diagnose the health status of the MWFFLG life community,and analyze the coupling and coordination relationship among the different subsystems.[Results](1)The overall health status of the MWFFLG life community in the YREZ from 2000 to 2018 showed an improvement trend;spatially,the health ranking was in the order:Midstream>Upstream>Downstream.(2)The longitudinal diagnosis results of the health status of different subsystems were:field subsystem>water subsystem>mountain subsystem>grass subsystem>lake subsystem>forest subsystem.(3)There were 46 system combinations in the coupling associations among the six subsystems in the YREZ,most of which had coupling indices exceeding 0.8,which were all at a high level of coupling;however,the coordination coefficients of most system combinations were slightly out of adjustment(0.3-0.5).(4)Forestry yield,forest stock volume,lake area,per capita aquatic products,and total fishery output value were the main driving factors for the health of the MWFFLG life community in the YREZ.[Conclusions]The MWFFLG life community in the YREZ had been developing in a healthy way,and the coupling and coordination among systems were on the rise.
