| 摘要: |
| 根据2005年的综合调查资料和1980年以来的常规监测资料,分析了云南高原深水湖泊抚仙湖透明度的空间分布、年际变化及影响因子.2005年6-7月抚仙湖水体透明度范围为0.5-6.2m,平均值为4.6m,透明度分布的总体格局是:南区>北区,湖心区>沿岸区,河口区较低.藻类和悬浮物是影响透明度空间分布的主要因子,随着水体中藻类和悬浮物的增加,透明度下降.近20多年来,抚仙湖透明度呈下降趋势,藻类增加是直接影响因子,水体总氮、总磷的增加促进了藻类的增殖,是重要的间接影响因子. |

| Abstract: |
| The spatial distribution, temporal changes of water transparency and their influencing factors in Lake Fuxian, a deep lake in Yunnan Plateau, were analyzed according to the investigations during June-July in 2005 and the regular monitoring data since 1980. The Secchi disk transparency varied from 0.5-6.2m with an average value of 4.6m in Lake Fuxian during June-July in 2005, The spatial distribution pattern of transparency was: north area
