为研究水资源与关联要素的空间错配问题，基于水网视角，根据适配理论和水资源多维属性理论，提出了包含资源层、社会层、经济层和生态层的水资源与关联要素适配性评价方法，并应用于南水北调中线一期工程影响区。结果表明:该方法可较为合理、系统地揭示水资源与关联要素的适配特征;2016-2020年南水北调中线一期工程影响区水资源与关联要素空间分布相对合理，整体基尼系数为0。388，资源层和社会层水资源与关联要素空间适配性较好，基尼系数分别为0。283和0。284，而经济层和生态层水资源与关联要素错配问题严重，基尼系数为0。501和0。486;南水北调中线一期工程通水后，水资源与关联要素的空间适配性在资源层、社会层、经济层有不同程度改善，在生态层变化不大。
Adaptability evaluation of water resources and associated elements based on perspective of water network
To study the spatial mismatching between water resources and associated elements,an adaptability evaluation method for water resources and associated elements,including resource layer,social layer,economic layer,and ecological layer,was proposed according to the adaptation theory and multi-dimensional attribute theory of water resources from the perspective of water network.Further,the method was applied to the affected area of the first phase of middle route of the South-to-North Water Diversion Project(SNWDP).The results showed that the proposed method can reveal adaptation characteristics of water resources and associated elements reasonably and systematically.The spatial distribution of water resources and associated elements was relatively reasonable in the affected area of the first phase of middle route of the SNWDP for the period 2016-2020,with an overall Gini coefficient of 0.388.Water resources and associated elements showed good spatial adaptability in resource layer and social layer,with Gini coefficients of 0.283 and 0.284,respectively.However,serious mismatching between water resources and associated elements occurred in economic layer and ecological layer,with Gini coefficients of 0.501 and 0.486,respectively.With the implementation of water transfer in the first phase of middle route of the SNWDP,the spatial adaptability of water resources and associated elements in resource layer,social layer,and economic layer has been improved in different degrees,while ecological layer has little change in spatial adaptability.
