摘要
基于物元分析法和熵组合权重法对重庆市三峡库区水资源承载力进行评价。研究结果表明,万州区、丰都县以及巫山县等9个区县水资源承载力等级为"可载"或"向可载"转化,占库区总区县个数的40.91%;涪陵区、长寿区、巴南区等5个区县水资源承载力等级为"满载"或"向满载"转化,占库区总区县个数的22.73%;渝中区、江北区以及大渡口区等8个区县水资源承载力等级为"超载"或"向超载"转化,占库区总区县个数的36.36%。重庆市三峡库区水资源承载力主要影响因子是人均水资源量、人均用水量和城市化水平以及废污水排放率等。
Based on the analysis of the characteristics of water resources carrying capacity and problems in Chongqing TGP reservoir area,this paper evaluated water resources carrying capacity with the theory of combined weight on principle of relative entropy and matter element model.The results showed that the water resources carrying capacity distributed as follow： the grade of 9 districts were of non-full load or a non-full load trend in southest or northest Chongqing City,which accounted for 40.91% of the total area;the grade of 5 districts were of full-load or a full-load trend,which accounted for 22.73% of the total area;the grade of 8 districts were of overloading or a overloading trend in southwest of Chongqing,which accounted for 36.36% of the total area;the main factors of water resources carrying capacity were amount of water resource capacity per capita,water consumption per capita,rate of urbanization,rate of waste water discharge and so on.
