| 中文摘要 |
| 应用Sanders氏稀疏曲线法及Shannon-Wiener多样性指数法对滇池不同水域浮游动物种类和数量进行分析,结合指示种的分布情况分析结果表明,①滇池草海和外海的污染状况有明显的不同,草海处于α中污染阶段,外海处于β中污染阶段;②滇池污染的梯度变化:新河>楼外楼>草海中>灰湾>大河尾>观音山中;③草海正趋向于池沼泽化。 |

| Analysis of the species and mass population of zooplankton was carried out by means of Sander's sparse curve and Shannon-Wiener's diversity index on different regions of lake Dianchi. Integrated with the output of the analysis of zooplankton indicator distribution, the following results were obtained: (1) the extent of pollution is obviously defferent in the inlake from the outlake i. e. the intake is in a stage of pollution and the outlake is in β stage. (2) the gravity of pollution in different regions of lake Dianchi are: the exit of river Xinhe>the exit of river Daguang>the center of inlake> Huiwan> Darhewei> the middle of Guanyinshan. (3) the inlake is in the process of swamping. |
