摘　　要：为构建生态与经济协调发展提供理论基础,加强对水土资源与经济发展的耦合机制和互动关系的理解。以三门峡为研究区域,首先通过构建耦合协调度模型,分析2000—2020年水–土–经济的耦合协调度在时间上的变化趋势;然后采用通径分析,定量探究水土资源对经济发展的驱动作用。结果显示:土地资源与经济发展的耦合协调度自2004年逐渐增长,至2009年达到协调发展状态;而水资源与经济发展耦合协调度在2000—2012年期间濒临失调,从2012年起开始快速增长,并于2015年达到高度协调的程度;水土资源与经济发展的耦合协调度在2000—2014年呈波动上升的趋势,2015年后达到高度协调状态。水土资源对经济发展有重要促进作用,并且土地资源对经济的驱动作用更强烈。[Background]The rational use of soil and water resources is not only related to the sustainability of the ecological environment,but also directly affects the overall regional economic growth,and in turn the regional economic development will,to a certain extent,destroy the soil and water resources.As an important economic zone in Henan province,Sanmenxia city is also one of the regions with serious soil and water erosion,and it is necessary to study the relationship between water-soil resources and regional economic development in Sanmenxia city.It is necessary to understand the coordination mechanism and interaction between water and soil resources and economic development to provide theoretical support for realizing the target tasks of ecological protection and high-quality development.[Methods]This study took Sanmenxia city as the research object and constructed the regional water-soil-economy composite system index system.This study determined the index weights by entropy weighting method and calculating the system comprehensive development indexes.Utilizing the system coupling theory,the coupling coordination model is constructed.This study investigated the change of the coupling coordination degree between the two and the three water-soil-economic systems in Sanmenxia city from 2000 to 2020.After that,this study adopted the path analysis to explore the role of water and soil resources on regional economic development.[Results]The results of the comprehensive development indexes of the system showed that the level of economic development in Sanmenxia city from 2000 to 2020 shows a trend of increasing year by year.Water resources began to show a fluctuating upward trend after 2014.Land resources showed a gradual upward trend after 2004.The results of the coupling coordination degree model showed that the coupling coordination degree of land resources and economic development grows gradually after 2004,and began to reach a high degree of coordination in 2016.The degree of coupling coordination between water r
