Dynamic Interactive Responses of Urbanization and Ecosystem Health in Land Border Areas in China
The purpose of this study is to explore the changes of urbanization and ecosystem health in land border areas and the characteristics of their mutual decoupling status,to provide reference for the coordinated development of regional economy and environment.The research methods include the measurement of urbanization development,assessment of ecosystem health,random forest modeling and decoupling analysis.The results show that:1)temporally,comprehensive urbanization has transitioned from an embryonic stage to an initial growth phase,characterized by an upward trajectory in population,land use,economic and social urbanization.Conversely,ecosystem health has exhibited a fluctuating downward trend,indicating a deterioration in natural health despite an enhancement in overall ecosystem services.2)Geographically,areas with advanced comprehensive urbanization tend to cluster in Inner Mongolia,whereas less developed regions are predominantly situated in Xinjiang.Conversely,regions presenting higher ecosystem health indices are concentrated in Northeast China,Yunnan-Guangxi,and Tibet,with Inner Mongolia and Xinjiang exhibiting lower indices.3)The influence of land urbanization on ecosystem health dynamics has become increasingly pronounced.4)The decoupling relationship between urbanization and ecosystem health has undergone a transition from expansively negative decoupling to a stronger decoupling trend during the period of 2000-2020.In conclusion,the decoupling status and significant regional disparities in the interaction between urbanization and ecosystem health in land border areas underscore the need to tailor ecological conservation measures that prioritize sustainability in both economic and environmental domains.
