摘　　要：为深入理解土地利用变化与生态系统生产总值(GEP)间的耦合关系,为当地政府实现经济与环境协同发展提供理论参考,本文以浙江省建德市为研究对象,计算其2010、2015、2020年的GEP,并构建土地利用强度指标体系,以耦合协调度模型分析土地利用强度与GEP的关联并分析其机理。结果表明,2010—2020年,建德市的土地利用强度逐年增加,土地利用变化较大,主要体现在林地、耕地和建设用地上;GEP增加192.93亿元,增幅为36.73%;土地利用强度与GEP处于良好耦合协调向优质耦合协调过渡阶段,耦合协调度逐年上升,2020年耦合协调度达到0.7240,整体向好发展。Gaining a deep understanding of the coupling relationship between land use changes and Gross Ecosystem Product(GEP)can provide theoretical references for local governments to achieve the coordinated development of economy and environment.Taking Jiande City,Zhejiang Province as the research subject,this paper calculates its GEP for the years 2010,2015,and 2020,constructs a land use intensity index system,and employs a coupling coordination model to analyze the association between land use intensity and GEP and to explore its underlying mechanisms.The results show that from 2010 to 2020,the land use intensity of Jiande City has increased annually,with significant land use changes mainly occurring in forest land,arable land,and construction land.The GEP has increased by 19.293 billion yuan,with an increase rate of 36.73%.The relationship between land use intensity and GEP is transitioning from good coupling coordination to superior coupling coordination.The coupling coordination degree is rising annually,reaching 0.7240 in 2020,showing overall positive development.
