摘要
从滇池流域地形、流域水系、流域土地利用及滇池湖盆形态等几个方面的地理特征出发,研究分析这些地理特征对滇池水污染的影响。流域地形决定了滇池是全流域水流及其承载的各种污染物的最终受纳水体。流域水系特征加之水资源的匮乏造成了高污染水入湖。流域土地利用格局造成了大量污染物的产生且易入湖。流域、湖盆形态导致了入湖污染物在湖中的充分滞留及沉积污染物的易释放。
The impacts resulted from geographical characters including terrain, water system, land utilization and the shape of the lake on water pollution in Dianchi lake basin are analyzed. The basin terrain leads to the Dianchi lake being the receiving water body of the whole basin water containing the pollutants, which leads to serious polluted water into the lake. The land utilization style produces lots of pollutants which are easy to flow into the lake. The shape of the lake makes the pollutants stay longer and release easier in sediment of Dianchi lake.
