| 摘要: |
| 气候变暖下湖泊富营养化进程是近年研究热点之一.本文对1980-2009年期间洱海富营养化进程研究发现,水体总磷、总氮与气温均呈升高趋势.气温、水体总磷和总氮均能显著促进浮游植物增长.统计分析表明,气温对浮游植物增长的促进作用不受水体总氮、总磷的影响;水体总磷对浮游植物增长的促进作用不受气温的影响,受水体总氮的影响;水体总氮对浮游植物增长的促进作用不受气温和水体总磷的单独影响,受它们共同的影响.因此,气候变暖与营养水平的增加共同促进了洱海的富营养化进程. |

| Abstract: |
| Eutrophication under climate warming is a hot topic in limnology recently.Our study demonstrated that epilimnetic total phosphorus (TP),total nitrogen (TN) and air temperature increased with the process of eutrophication in Lake Erhai in 1980-2009.Statistics analysis demonstrated that,air temperature promoted the growth of phytoplankton with no effect from TP and TN, TP promoted the growth of phytoplankton with no effect from air temperature but with effect from TN,TN promoted the growth of phytoplankton with no effect from air temperature and TP individually but with effect from their interaction.Climate warming and nutrient enrichment promote eutrophication of Lake Erhai together. |
| Key words: Eutrophication climate warming phosphorus and nitrogen enrichment Lake Erhai |
