三峡库区事故型水污染敏感目标辨识研究

Research on Identification of Sensitive Targets of Accidental Water Pollution in the Three Gorges Reservoir Region

集中饮用水源地是三峡库区内易受事故型水污染影响的重要敏感目标,本文以集中饮用水源地为研究对象,开展三峡库区事故型水污染敏感目标辨识研究.研究结果表明:三峡库区内事故型水污染敏感目标(集中饮用水源地)共有99个,主要分布在重庆库区,为700余万人提供饮用水服务,其中服务人口10万人以上(包含10万)的集中饮用水源地有18个,重庆市九龙坡区、沙坪坝区、江北区和南岸区等区县内集中饮用水源地服务人口的数量较多;三峡库区共有特大敏感目标23个,重大敏感目标28个,二者占敏感目标总数的51.52%,且主要分布在三峡库区重庆段.

Concentrated drinking water sources are the important sensitive targets of accidental water pollu‐tion that easy to be polluted in the Three Gorges Reservoir area （TGRA） .With concentrated drinking wa‐ter sources as research object ,the sensitive targets in the TGRA have been identified .The results show that there are 99 sensitive targets （concentrated drinking water sources ） mainly distributed in the Chongqing Section in the research area ,providing drinking water for more than 7 million individuals .A‐mong these sensitive targets ,18 have been found to provide more than 10 million populations .T he drink‐ing water sources in Jiulongpo District , Shapingba District , Jiangbei District , and Nan＆#39;an District in Chongqing offer relatively more people with drinking water .In addition ,there are 23 serious sensitive tar‐gets and 28 major sensitive targets ,w hich accounts for 51 .52% of the w hole number of the sensitive tar‐gets in the TGRA ,and mainly distributed in the Chongqing section .
