【摘要】 螳螂川是滇池的唯一出口河道,下游称为普渡河,汇入金沙江。对该河的水生生物,过去尚未开展过调查。我们于1982年首次对该河的藻类植物进行了调查,鉴定出藻类植物160种,其中绿藻占绝对优势。 我们沿河选了六个采样点,第一个采样点选在河的源头,最后一个采样点选在富民普渡河大桥,其余四个采样点分布在该两个采样点之间的不同河段。调查结果表明:头尾两个采样点的藻类种类明显多于其余四个采样点,这与上游河水受沿岸工厂排放的有毒污染有密切关系。更多还原

【Abstract】 Tanglangchuan River is the only outlet of the Dianchi Lake, It ’ s lower reaches are called Puduher River, which flows into Changjiang River. In 1982, we investigated the algae in this river for the first time. We have identified 160 species of algae, among which green algae, Chlorophyta are dominant.We chose six points along the river, the first point is at the head of the river and the last one is at Puduher River Bridge in Fumin County, other four points are at the different parts of the river. The results of the investigation show that at the first and the last points there are more species of algae than that at the other four points. This is, we think, due to the pollution of the water by poisonous substances from the factories beside the upper reaches of the river.更多还原
