摘　　要：水资源短缺与水环境恶化已成为京津冀经济社会可持续发展的主要制约因素,水资源承载力评价是区域水资源合理配置的关键。本文从水资源系统对经济、社会系统的支撑角度出发,选取11个主要影响水资源承载力系统的因素作为评价指标,建立了基于水量、水质、水域、水流的水资源承载力评估方法,研究外调水对京津冀水资源承载力的影响。结果表明京津冀地区水资源承载力都属超载,天津、北京尤为严重。京津冀地区水资源承载的压力主要来自于水资源系统,水资源短缺是京津冀水资源承载力超载的主要因素,人均水资源量是影响区域水资源承载力的关键因子。外调水对改善京津冀水资源承载力具有一定贡献,尤其是对北京、天津的影响较为显著。在水资源短缺时期外调水的影响更为明显,在2000年特枯年,天津市引滦与引黄入津使得水资源承载力提高了13%。南水北调使得2015年北京、天津两地水资源承载力分别提高了5%。外调水对水资源承载力影响研究为京津冀水资源的合理利用提供了依据,对于实现水资源与经济社会的协调发展具有重要意义。The water resources shortage and water environment worsen have been becoming primary restraining factors to development of economy and society in Beijing-Tianjin-Hebei region. The evaluation of water resources carrying capacity is the key to regional water reasonable utilization. In this paper, according to the view of development of economy and society is supported by water resources, the eleven factors which mainly effect water resources carrying capacity have been selected as assessment indexes. An evaluation approach of research the effect on water resources carrying capacity by water transfer based on water quantity, water quality, water area and water flow has been established. The results indicate that the water carrying capacity are belong overloaded in Beijing-Tianjin-Hebei region, especially in Tianjin and Beijing. The carrying press is mostly from water resources system, the water shortage is the major reason of water carrying capacity overloading in Beijing-Tianjin-Hebei region, and the per capita water resources is the key factor to regional water carrying capacity. The water transfer is certainly important to improve water carrying capacity in Beijing-Tianjin-Hebei region, especially for Beijing and Tianjin. In drought period, the results of improve water carrying capacity by water transfer is more evident, for example the water resources carrying capacity had been improved 13% in Tianjin through water transfer from Luan River and Yellow River to Tianjin in 2000, when is very dry year.The south water to north make water carrying capacity improve 5% in Beijing and Tianjin,respectively. It supply an foundation for water resources reasonable utilization in Beijing-TianjinHebei to research of effect on water resources carrying capacity by water transfer, and it is also important to realize the harmony among water resources, economy and society in region.
