摘　　要：土地利用与生态系统服务的影响研究是生态学和地理学的重要内容,研究其耦合协调关系,可为土地利用与生态系统服务协调互动与高质量发展提供决策参考。本文在分析1990年—2020年期间的土地利用综合程度及生态系统服务价值时空演化的基础上,采用耦合协调度模型探讨了土地利用程度与生态系统服务耦合协调关系。研究发现:(1)洞庭湖区土地利用综合指数在研究期间不断提高,土地开发利用集约程度较好,生态服务价值综合指数呈平稳增长势态;(2)土地综合利用程度与生态系统服务价值耦合度比较稳定,协调度皆处于中度协调阶段,在时间演进特征总体表现出平稳发展态势,所有服务类型的耦合度在研究期间基本呈现上升趋势,但协调度所呈现的规律不明显,较为复杂;(3)各县域耦合特征的空间分布呈现复杂的动态耦合关系,耦合度总体呈上升趋势,但耦合协调度普遍较低。Land use is an important factor affecting ecosystem services.Decision-making reference for the coordination and high-quality development of land use and ecosystem services can be provided by analyzing the coupling and coordination relationship between comprehensive land use and ecosystem services.Based on the analysis of the spatial and temporal evolution of land use and ecosystem service value from 1990 to 2020,the coupling coordination model is used to explore the coupling coordination relationship between land use and ecosystem services.The results indicate that:(1)The comprehensive index of land use in Dongting Lake region was continuously improved during the study period,the intensive degree of land development and utilization was good,and the comprehensive index of ecological service value increased steadily.(2)The coupling degree between land use and the ecological services value is relatively stable,and the coordination degree is in a moderate coordination stage,and overall change trend is stable.The coupling degree of all types of ecosystem services basically shows an upward trend during the study period,but the coordination degree is more complex than the coupling degree.(3)The spatial distribution of the coupling characteristics reveals a complex dynamic relationship,and the coupling degree is generally on the rise,but the coordination degree is generally low.
