【摘要】：随着社会用水和排泄强度的不断增大,水资源数量和质量成为区域生态环境和社会经济协调发展的主要约束因子,也是影响水资源承载的主要因素。本文从水资源、经济社会、水生态、水环境综合角度,基于"量、质、域、流"四大方面构建水资源承载力"四层三级"评价指标体系,提出水资源承载状况的评价标准、评判方法和水资源承载类型的划分方法,为水资源承载力评估和状态诊断提供方法支撑。本文以天津市为例开展现状水资源承载力评估分析,研究表明:天津市在入境和本地水总水量35.98亿m~3、生态补水2.8亿m~3、出境水量12.95亿m~3、污水一级A出水COD水质标准的情况下,天津市水量承载力区间为1 686万~1 772万人,水质承载力区间为1 169万~1 393万人,水资源承载力区间为1 169万~1 393万人,均值1 281万人;天津市水资源承载状况属于水资源超载区,类型为水质超承载型。
[Abstract]:With the increasing of social water use and discharge intensity, the quantity and quality of water resources have become the main constraint factors for the coordinated development of regional ecological environment and social economy, and also the main factors affecting the carrying capacity of water resources. Based on the four aspects of "quantity, quality, region and flow", the evaluation index system of water resources carrying capacity is constructed, and the evaluation standard of water resources carrying capacity is put forward. The evaluation method and the classification method of water resources bearing capacity type provide method support for water resources carrying capacity assessment and condition diagnosis. This paper takes Tianjin as an example to carry out water resources carrying capacity assessment and analysis. The results show that under the conditions of total water quantity of three billion five hundred and ninety-eight million mm3, ecological rehydration of 280 million mm3, outflow volume of one billion two hundred and ninety-five million mm3 and effluent COD quality standard of first class A effluent of Tianjin, the carrying capacity of Tianjin water is 16.86 million to 17.72 million people. The range of water quality carrying capacity is 11.69 million ~ 13.93 million people, the range of water resources carrying capacity is 11.69 million ~ 13.93 million people, the average is 12.81 million people, the water resources carrying capacity in Tianjin belongs to water resources overload area, and the type of water resources carrying capacity is water quality overloading type.
