摘　　要：[目的]以广西百色市所属县区为典型研究样区,利用投影寻踪评价法对研究区水资源支撑能力进行综合评价。[方法]采用两维图论聚类算法,以区域水资源支撑能力和区域社会经济发展能力为分类对象,探讨我国典型喀斯特地区水资源对社会经济发展的支撑能力,构建区域水资源支撑能力的图论聚类分析模型,定量表达区域水资源支撑社会经济发展能力的空间聚类。[结果]百色市水资源对社会经济发展的支撑能力可以分为右江河谷澄碧河以下地区、澄碧河流域地区、非右江流域县区。通过投影寻踪评价的降维和两维图论聚类分析对区域空间关系的考虑,2种方法的综合运用可以得到相互补充和有机结合。[结论]两维图论聚类能较好地反映水资源对社会经济发展的支撑能力和空间相关性,其结果将有助于决策者制定区域水资源规划和发展战略。[Objective]Taking the counties in Baise City of Guangxi as a typical research area,a comprehensive evaluation of water resources support capacity in the study area was conducted using the projection pursuit evaluation method.[Method]A two-dimensional graph clustering algorithm was used to classify the regional water resources support capacity and regional socio-economic development capacity. This study explored the support capabilities of water resources in the typical Karst regions in China for social and economic development,and built a map of regional water resources support capabilities. The class-analysis model quantitatively expressed the spatial clustering of regional water resources supporting social and economic development capabilities.[Result]The supporting capacity of water resources in Baise City for social and economic development could be divided into areas below the Chengbi River in the Youjiang Valley,the Chengbi River Basin and non-Youjiang River Basin counties. By considering the dimensionality reduction of the projection pursuit evaluation and the two-dimensional graph theory cluster analysis on the regional spatial relationship,the comprehensive application of the two methods could be complemented and organically combined. [Conclusion]The two-dimensional graph theory clustering can better reflect the supporting capacity and spatial correlation of water resources for social and economic development,and the results will help decision makers formulate regional water resources planning and development strategies.
