摘　　要：对降雨过程中桃花江氨氮和总磷两项指标进行了监测,结果表明桂林市桃花江水质受降雨径流污染较为严重.尤其是径流形成初期,在各取样点上氨氮、总磷浓度最大值分别为4.565和0.615mg/L,分别超出地表Ⅲ类水标准4.6和3.1倍,超出水体富营养化标准22.8和30.8倍,水体富营养化趋势明显.In raining time, ammonia nitrogen and total phosphorus are monitored in Guilin Taohuajiang River. The results indicate that the water quality of Taohuajiang River is seriously influenced by rainfall runoff. Especially at early stage of runoff, the concentration of NH3-N amounts to 4. 565 mg/L and is 4. 6 times higher than the Ⅲ class of ＂Environmental quality standard for surface water＂, 22. 8 times higher than the eutrophication standard for water bodies. TP concentration reaches 0.615 mg/L, 3.1 times higher than the Ⅲ class of ＂Environmental quality standard for surface water＂ and 30.8 times higher than the eutrophication standard for water bodies . The tendency of water body eutrophication is obvoius.
