| 摘 要： | 于2009年5月和8月对辽河太子河水系的浮游植物进行了野外调查研究。结果表明：辽河太子河水系的浮游植物主要由硅藻、绿藻和蓝藻组成,共鉴定出浮游植物195种,其中硅藻门种类最多,共鉴定出97种;绿藻门次之,共鉴定出55种;蓝藻门居第3位,共鉴定出25种;藻类的密度具有明显变化,从5月开始总藻类密度开始减少,而蓝藻门的藻类密度却明显上升,从占总藻类密度的7%上升到17%;从浮游植物多样性指数分布上看,太子河水系不同区域浮游植物多样性的差异性显著,太子河水系上游地区浮游植物多样性小于下游地区。 |

| Abstract: | This paper represents the investigation on phytoplankton in Taizi River watershed from May to August of 2009. The results showed that the phytoplankton was dominated by diatoms, green algae and blue-green algae. 195 species of phytoplankton were identified, including 97 species of diatoms, 55 species of green algae and 25 species of blue-green algae. The diatoms were the most important species, followed by green algae and blue algae in 2009. The cell densities of phytoplankton were found to he reduced quickly from May to August of 2009. However, the cell densities of blue algae were increased from 7% to 17%. Meanwhile, two kinds of diversity index were analyzed and compared in different regions of Taizi River tributary. There were significant differences in phytoplankton diversity, indicating that the diversity index was found less in the upstream than that in the downstream. |
