| 摘 要： | 摘要：为了研究城市降雨径流对桂林四湖水质的影响，在某场强降雨的前后，对桂林四湖湖水的氨氮、总磷、高锰酸盐指数和浊度进行了监测与比较，结果显示降雨中各指标农度高于降雨前。其中变化最明显的是氨氮和高锰酸盐指数。在雨后60min，由于湖水的自净作用，湖水的高锰酸盐指数和浊度明显下降，而氨氮和总磷浓度的值下降不明显。总的来说，城市雨水径流对湖水具有一定程度的影响。

| Abstract: | To study the influence of rainfall runoff on four lakes in Guilin, ammonia nitrogen , total phosphorus, potassium permanganate index and the turbidity are monitored in raining time. The results showed that the higher concentration of water quality in raining than before the rain ,especially ammonia nitrogen and potassium permanganate index are changed greatly. The concentration of permanganate index and turbidity are lowed obviously for the water self-purification after the rain. But the concentration of ammonia nitrogen and phosphorus are not lowed obviously. In general, the water quality of four lakes is certainly influenced by rainfall runoff. |
