| 摘 要： | 2010年4月对微山湖不同水域叶绿素a含量和初级生产力进行调查，并就环境因子对其影响进行了研究。结果表明，微山湖叶绿素a平均含量为6.29 μg/L，表现为入湖河道>航道区>养殖区；初级生产力均值为188.67 mgC/(m3?d)，表现为入湖航道>养殖区>湖区航道；逐步回归分析发现，总氮、总磷对微山湖叶绿素a含量影响显著；总磷含量对入库河流叶绿素a含量影响显著。总磷含量对微山湖、入湖河流初级生产力影响显著；磷酸盐含量对入湖河流初级生产力影响显著。

| Abstract: | In April 2010,the content of chlorophyll a,primary production and their relationships with environmental factors were studied in the different portion of Weishan Lake.The results showed that average content of chlorophyll a was 6.29 μg/L;it showed that entryway portionsea-route portionbreed portion.Average content of primary production was 188.67 mgC/（m 3 ·d）;and it showed that entryway portionbreed portionsea-route portion.Stepwise multiple regressions were used to study the influence of environment factors to chlorophyll a and primary production,and the results showed that the chlorophyll a content of Weishan Lake was significantly impacted by total nitrogen and total phosphorus;chlorophyll a content of entryway portion was significantly impacted by total phosphorus.Weishan Lake primary production was significantly impacted by phosphorus content;and primary production in entryway portion was significantly impacted by total phosphorus and phosphate. |
