黄河沿线市域生态系统服务供需与人类活动强度的时空耦合关系
Spatial and Temporal Coupling Relationship Between Ecosystem Service Supply and Demand and Human Activity Intensity in Municipal Areas along the Yellow River
摘要
Abstract
This study aims to clarify the supply and demand of ecosystem services and reveal the coupled and coordinated relationship between ecosystem services and human activities,so as to provide a basis for promoting the coordinated devel-opment of humans and ecosystems in the future.Taking the municipal area along the Yellow River as the study area,this paper combines multi-source data and the equivalent factor method,as well as indicators such as population density,eco-nomic density and the degree of land use development.The supply and demand of ecosystem services from 1990 to 2018 were quantified,and the coupling coordination degree model was further used to analyze the coupling coordination relation-ship between the ecosystem services and the intensity of human activities.The results are as follows.From 1990 to 2018,the total value of ecosystem services in the study area decreased first and then increased,with an increase of 8.43 billion yuan during the study period.The demand for ecosystem services has shown an increasing trend,especially after 2000,with a significant increase in the eastern part of the study area.Municipalities with low supply-high demand in the study area are located mainly in the eastern part of the study area,and municipalities with low supply-low demand are located mainly in the central part of the study area,surrounded by municipalities with high supply-low demand.From 1990 to 2018,the intensity of human activities in the study area showed an increasing trend,and the increase was most significant spatially in the eastern region of the municipality.From 1990 to 2018,the coupled coordination degree between ecosystem service sup-ply,demand and intensity of human activities in the study area all showed a trend of first decreasing and then increasing.The coupling coordination between ecosystem service provision and human activity intensity was the highest in all years,but the spatial distribution heterogeneity was smaller than that between ecosystem service demand and human activity intensity.The results of the study can provide a basis for coordinating the development of ecological protection and human activity strategies in the municipal areas along the Yellow River.关键词
