摘  要：
为了解红枫湖水体理化特征与浮游植物结构群落变化关系,于2014年1—12月对红枫湖大坝、花鱼洞、后午等采样点进行了月度野外采样监测与室内分析。应用综合营养状态指数(TLI)、藻类丰度与湖泊营养类型的评价标准对红枫湖水体营养状态进行评价,对主要水体理化特征与浮游藻类丰度的关系进行分析。结果表明:1)共鉴定出浮游植物7门,105种(属),主要为蓝藻、绿藻和硅藻。2)全年藻类丰度呈现出春季、秋季两个峰值,多数月份以蓝藻门的假鱼腥藻(Pseudanabaena sp.)为主,以绿藻门的双对珊藻(Scenedesmus bijugatus)、小球藻(Chlorella vulgaris)及硅藻门中的小环藻(Cyclotella sp.)为辅。3)红枫湖水体处于中营养-中度富营养化状态。4)相关性分析表明,水温、溶解氧、总氮、透明度是红枫湖藻类丰度的主要影响因素。本研究为红枫湖水环境保护和富营养化治理提供了重要的科学基础。

摘  要：
To clarify the relationship between water physicochemical characteristics and phytoplankton community in Hongfeng Lake,water samples were monthly collected and analyzed at three sites( DB,HYD,and HW) in 2014. The trophic level index( TLI),algal abundance,and evaluation criteria for lake trophic type were used to evaluate the eutrophic level of Hongfeng Lake. The correlation between environmental factors and the abundance of phytoplankton were analyzed. The results showed that:( 1) A total of 105 species( belonging to seven phyla) of phytoplankton were identified in the lake,dominated by cyanobacteria,green algae,and diatom.( 2) Algae abundance peaked in spring and autumn,with Pseudanabaena sp. being the dominant specie in most months,followed by Scenedesmus bijugatus,Chlorella vulgaris and Cyclotella sp.( 3) The eutrophic level of Hongfeng Lake ranged from mesotrophic to moderate eutrophication.( 4) Results of correlation analysis showed that water temperature,dissolved oxygen,total nitrogen concentration,and water transparency were the major factors influencing the abundance of algae. Our results provide important scientific foundation for water environment protection and eutrophication control in Hongfeng Lake.
