快速城市化背景下重庆市生态系统服务价值时空特征及驱动因子分析
Analysis of spatiotemporal characteristics and driving factors of ecosystem service values in Chongqing City under rapid urbanization
摘要
Abstract
[Objective]To analyze the spatiotemporal dynamics and driving factors of ecosystem service value(ESV)under rapid urbanization,thereby deepening the understanding of human-land coupling mechanisms and laying a foundation for constructing ecological security patterns and promoting urban and rural sustainable development.[Methods]Taking Chongqing City as the study area,this study analyzed the spatial variations,interaction patterns,and influencing mechanisms of 11 ecosystem service values within the region,and divided the region into different ecological service functional zones accordingly.[Results](1)From 2000 to 2020,Chongqing City experienced significant changes in land use structure.Specifically,construction land showed the largest expansion,increasing 2.5 times over 20 years,with 86.31％of the land converted from cultivated land.(2)The total ESV in Chongqing City showed an increasing trend,with hydrological regulation contributing dominantly-accounting for 72.75％of the total increment.(3)The spatial differentiation of ESV in Chongqing City displayed a pattern of lower values in the center and higher values in the surrounding regions.Low-value areas were concentrated in highly urbanized core districts and their suburbs,while high-value areas were located in nature reserves or areas distant from urban center.(4)From 2000 to 2020,synergistic relationships dominated among the 11 ecosystem services in Chongqing City,accounting for 89.09％.(5)Geodetector results showed that socioeconomic factors explained the spatial variation of ESV more effectively than natural factors.The main driving factors included population density,rural per capita net income,gross regional product,fiscal revenue level,land use intensity,and real estate development.(6)Chongqing City was divided into three functional zones:value-added zone(8.34％),stable zone(78.13％),and degraded zone(13.53％).[Conclusion]From 2000 to 2020,Chongqing exhibited distinct spatiotemporal dynamics in land use structure and ESV,characterized by value increase,spatial differentiation,and service synergy.Socioeconomic factors played a dominant role in the spatial differentiation of the ESV.关键词
