摘要
[目的]估算桂林市城区主要污染物入河量。[方法]根据用水量对桂林市城区城镇污染源包括生活源、工业源、规模化畜禽养殖源和农业面源（COD和NH3－N）的入河量进行了估算。[结果]城镇生活源和工业源是桂林市城区主要污染物入河量的主要来源；城镇生活源和工业源贡献比例分别为27．6％～31．4％和58．7％～59．7％；桂林市区和其他区县贡献比例分别为35．6％～37．1％和62．9％～64．4％；桂江流域贡献比例最大，为66．8％～68．3％，其次是柳江下游，比例为25．7％～26．8％。[结论]经估算，桂林市城区污染源的COD和NH 3－N入河量分别为24952．57和3276．31 t／a。
Abstract
Objective] The aim was to estimate the quantity of major pollutants into river in urban area of Guilin City.[Method]According to water consumption, the quantity of COD and NH 3-N from urban pollution sources including living source , industrial source,large-scale live-stock and poultry breeding source and agricultural surface source into river in urban area of Guilin City were estimated .[ Result]The results showed that:urban living and industrial sources are the main sources of the major pollutants into river in the research area ;the contribution ra-tios of urban living and industrial sources are 27.6%-31.4%and 58.7%-59.7%, respectively;the contribution ratios of inner-city and its suburbs are 35.6%-37.1% and 62.9%-64.4%, respectively; the largest contribution ratio is from Guijiang river basin with 66.8% -68.3%; and the second contribution ratio is from the lower reaches of Liujiang river basin with 25.7%-26.8%.[Conclusion] The quantity of COD and NH3-N into river from urban area of Guilin City is estimated as 24 952.57 and 3 2763.1 t/a, respectively.
