摘要
【目的】随着人类活动对生态系统干扰的日益加强,分析黄河流域生态系统服务供需的变化特征及其与人类活动的交互作用,能够为生态保护和可持续发展策略的制定提供理论依据。【方法】采用当量因子法核算1980—2020年黄河流域生态系统服务供给量,以土地利用开发程度、人口密度和经济密度核算生态系统服务需求量,并基于供需分析和人类活动强度的量化结果,采用双变量空间自相关分析方法揭示了两者之间的交互关系。【结果】结果表明:1980—2020年,黄河流域生态系统服务供给呈现先减少后增加趋势,总体减少了14.43×10^(8)元;生态系统服务需求增加,特别是在2000年后增加更明显,2020年呈现自西向东递增的空间格局。黄河流域低供给-高需求的地级市主要位于研究区东部地区,低供给-低需求的地级市主要位于中部地区且被高供给-低需求的地级市围绕。人类活动强度呈现东部地区较高,而西部地区较低的特征,且随时间推移在增强。黄河流域生态系统服务供需与人类活动强度之间表现为显著的空间负相关性,并且在局部尺度呈现出High-Low集聚、Low-High集聚和Low-Low集聚三种集聚模式。【结论】研究结果可视化了黄河流域生态系统服务与人类活动在空间上的权衡关系,能够为协调生态保护与人类活动的政策制定提供科学指引。
[Objective]With the increasing human interference on the ecosystem,revealing the changing characteristics of ecosystem service supply-demand and the interactions with human activities in the Yellow River basin to provide theoretical basis for the formulation of ecological protection and sustainable development strategies.[Methods]The equivalence factor method was used to account for ecosystem service supply from 1980 to 2020,and ecosystem service demand was calculated based on the degree of land use development,population density and economic density.Then,based on the quantitative result of supply-demand analysis and human activity intensity,the interaction between them was revealed by bivariate spatial autocorrelation analysis.[Results]The result showed that from 1980 to 2020,the ecosystem service supply in the Yellow River basin showed a trend of first decreasing and then increasing,with an overall decrease of 14.43×10^(8) yuan.The ecosystem service demand increased,especially after 2000,and showed a spatial pattern of increasing from west to east in 2020.The prefecture-level cities with lowsupply and high-demand in the Yellow River basin were mainly located in the eastern part of the study area,while the prefecturelevel cities with low-supply and low-demand were mainly located in the central part,and surrounded by the prefecture-level cities with high-supply and low-demand.The human activity intensity was higher in the eastern region and lower in the western region,and was increasing over time.There was a significant negative spatial correlation between ecosystem service supply-demand and the human activity intensity in the Yellow River basin,and three clustering patterns of High-Low,Low-High and Low-Low clustering were observed at the local scale.[Conclusion]The result visualize the spatial trade-offs between ecosystem services and human activities in the Yellow River basin,which can provide scientific guidance for coordinating ecological protection and human activities in policy making.
