摘　　要：研究目的:探究边境地区城镇化与生态系统健康的变化情况及两者的相互解耦状态特征,为区域经济和环境协调发展提供参考。研究方法:城镇化发展水平测定、生态系统健康评价、随机森林模型、解耦模型。研究结果:(1)在时间维度上,综合城镇化由萌芽阶段升为初步发展阶段,人口、土地、经济、社会城镇化水平均呈上升趋势;生态系统健康整体呈波动下降趋势,表现为生态系统自然健康下降,但综合生态系统服务指数提升。(2)在空间维度上,综合城镇化等级较高的地区多分布在内蒙区,等级较低的地区多分布在新疆区;生态系统健康指数较高的地区多分布在东北区、滇桂区和西藏区,指数较低的地区多分布在内蒙区和新疆区。(3)土地城镇化对生态系统健康变化的影响日益显著。(4)城镇化与生态系统健康间的解耦关系在2000—2020年呈现出由扩张性负解耦到强解耦的变化趋势。研究结论:边境地区城镇化与生态系统健康解耦状态多变且区域差异显著,沿边地区在发展经济的同时,需因地制宜提出生态保护措施,实现经济与环境的可持续发展。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.
