%X 本文以中国典型西南山地城市重庆市为对象，考虑水量、水质2个要素，采用“短板法”评价2015年、2020现状年和2025规划年重庆市各区县水资源承载力。结果表明，重庆市2015年、2020年和2025年无严重超载和超载区县；承载临界状态区县由2015年的7个减少为2020年的3个和2025年的2个(渝北区和酉阳县)。水资源承载力提升原因主要是用水效率提高、用水量的减少和水质提升。2025年渝北区水量承载状况指标将变为0.94，处于临界状态。建议渝北区加强节水或通过水权交易市场购买用水量控制指标。<br />
Taking Chongqing, a typical mountainous area in southwest China, as a case study, the water resources carrying capacity of each district and county in Chongqing in 2015, 2020 and 2025 are evaluated by short-board method (considering the situation of the worst factor). Two factors of water quantity and wa-ter quality are analyzed. The results show that there is no serious overloading and overloading county in Chongqing in 2015, 2020 and 2025, and the number of counties in critical state decreased from 7 in 2015 to 3 in 2020 and 2 in 2025. The improvement of water use efficiency, the decrease of water consumption and the improvement of water quality are the main reasons of water resources carrying capacity increase. The water quantity load index of Yubei District in 2025 will become 0.94, which will be in a critical state. It is suggested to strengthen water conservation or purchase water quantity control index through the water right trade market in Yubei District.
