摘　　要：围绕水资源承载主体、承载客体、途径3个维度,构建了水资源承载力评价指标体系,采用TOPSIS模型、耦合协调模型以及生产函数模型,对珠江区27个重点流域水资源承载状况进行了分析研究。结果表明:南渡江、桂江、万泉河、北江流域水资源承载力排位居前,九洲江、黄泥河、钦江、鉴江流域水资源承载力排位居后;重点流域水资源系统内部要素之间以濒临失调为主,濒临失调流域17个、轻度失调流域9个、中度失调流域1个;重点流域水资源承载效率曲线呈低、中、高3种类型,低效率型流域4个、中效率型流域12个、高效率型流域11个;综合水资源承载力排位、耦合协调程度以及承载效率,九洲江、鉴江、钦江流域水资源承载状况不佳,北江、西江、武水、贺江、汀江流域水资源承载状况相对较佳。研究结果可作为珠江区及重点流域水资源规划、开发、利用、保护和管理的重要参考。In this paper,the evaluation index system of water resources carrying capacity was built in terms of three dimensions of water resources carrying subject,carrying object,and approach.TOPSIS model,coupling coordination model,and production function model were used to analyze the water resources carrying status of 27 key basins in the Pearl River region.The results show that the water resources carrying capacity of Nandu River,Guijiang River,Wanquan River,and Beijiang River basins rank first,and that of Jiuzhou River,Huangni River,Qinjiang River,and Jianjiang River Basins rank second.The internal elements of the water resources system in the key basins are mainly characterized by near imbalance,with 17 near imbalance basins,nine mild imbalance basins,and one moderate imbalance basins.The water resource carrying efficiency curve of key basins shows three types:low,medium,and high.There are four low-efficiency basins,12 medium-efficiency Basins,and 11 high-efficiency basins.A comprehensive comparison of water resources carrying capacity ranking,coupling coordination degree,and carrying efficiency shows that the water resource carrying capacity of the Jiuzhou River,Jianjiang River,and Qinjiang River Basins is poor,while that of the Beijiang River,Xijiang River,Wushui River,Hejiang River,and Tingjiang River Basins is relatively good.The results in this paper can be an important reference for the planning,development,utilization,protection,and management of water resources in the Pearl River region and key river basins.
