| 摘 要： | 水质富营养化评价表明，洱海现属中营养水平，根据全年平均状态下的某些单项指标评分或近年来某些时段的全湖营养类型综合评分，将洱海评价为从中营养状态向营养营养状态过渡型的湖泊可能更为适宜。与历史资料相比，８０年代至今富营养化进程料快，主要营养盐守趋势。 |

| Abstract: | Analysis of water quality and evaluations show that the Erhai Lake is in a mesotrophic state. According to evaluations on some annual average state and on all lake nutrition types at some period of recent years, it is feasible that Erhai Lake now is assessed to the transition type between mesotrophic and eutrophic state. Compared with historical data, from the 1980s the pace of eutrophication was a little fast and the nutrients elements concentration increased gradually. Factors that result the changes are: (1 ) increasing of contaminants within the catchment; (2) lake being at low water level for a long time, and (3) unreasonable exploring of natural resources. |
| Keywords: | Erhai Lake eutrophication factor |
