【摘要】 采用多因子综合指数法和单因子评价法对潭江流域进行综合评价,评价结果表明:流域水质表现为有机污染型,污染程度呈分片分布,污染最严重的河段为干流中下游(三埠-牛湾段).因此在流域水质规划过程中应将生活污染源与禽畜养殖面源作为污染源控制的重点,必须按饮用水源优先保护的原则,重点作好中游水污染控制规划.更多还原

【Abstract】 A comprehensive assessment of the Tanjiang River Basin is made by adopting the multi-factor system and solo-factor assessment. The assessment results show: the water pollution in the Tanjiang Rier basin belongs to the organic pollution type, and different parts are different in degree of pollution. The most seriously polluted sectors are the lower and middle reaches. Therefore, when planning control of the water pollution, pollution produced by living quarters, livestock and domestic birds should be placed on the top of the priority list. The focus should be on the control of pollution in the middle and lower reaches so as to ensure the safety of the source of drinking water.更多还原
