云南生态系统服务与农户生计耦合协调关系时空变化研究OA北大核心CSTPCD

To promote the coordinated development of ecological protection and farmers'livelihood improvement in Yunnan Province,based on remote sensing monitoring data of land use status and socio-economic statistics in Yunnan Province from 2005 to 2020,we analyzed the spatiotemporal changes of ecosystem service value and farm-ers'livelihood level in Yunnan Province by using the equivalent factor method and entropy method,and analyzed the coupling coordination degree model and relative development degree model.The results showed that during the study period,the ecosystem service value in Yunnan Province showed a slow increase trend,and the overall spatial distribution was stable,showing a distribution feature of'high in the west and low in the east'.The livelihood level of farmers in Yunnan Province showed an upward trend,showing the spatial distribution characteristics of'high in the middle and low in the periphery'.The coupling and coordination development of ecosystem services and farmers'livelihood showed an overall optimization trend.The coupling and coordination stage mainly changed from the run-ning-in stage to the coordination stage,and the coupling and coordination type mainly changed to the synchronous development of ecosystem services and farmers'livelihood;there are apparent differences in spatial distribution,the development status of central Yunnan is better,the development status of eastern Yunnan is worse,and the devel-opment status of western Yunnan and southwest Yunnan is between them.Therefore,suggestions were put forward to enhance the value of ecosystem services according to local conditions,continuously improve farmers'livelihoods,and rationally coordinate the relationship between ecosystem services and farmers'livelihoods.
