摘要: 通过水体群落水平碱性磷酸酶活性分析方法,研究了2016年春季(4—5月)邛海河-湖系统浮游植物磷胁迫,包括邛海周边6条主要河流、河口和邻近湖域。结果表明,邛海春季河-湖系统浮游植物叶绿素浓度和碱性磷酸酶活性存在明显的空间异质性,进而导致不同河流和不同区域存在不同程度的磷胁迫现象,其中官坝河河流的胁迫程度最高,其次是官坝河河口、青河河口、鹅掌河邻近湖域,而青河邻近湖域的胁迫程度最低。

Abstract: Phosphorus stress of phytoplankton was determined by analysis of alkaline phosphatase activity during spring (April to May) in 2016 in river-lake and adjacent water system of Qionghai lake, including 6 major rivers, estuary and adjacent water around Qionghai lake. The result showed that there were obvious spatial heterogeneity in chlorophyll concentration and alkaline phosphatase activity of phytoplankton of the river-lake system of Qionghai in spring, indicating that different rivers and regions shows different phosphorus stress. Among all the study sites, the phosphorus stress was the highest in the Guanba river, and followed by estuary of Guanba river, estuary of Qing river and adjacent water of E’zhang river, while the adjacent water of Qing river showed the lowest phosphorus stress.

Key words: phosphorus stress, environmental factor, alkaline phosphatase activity, chlorophyll, river-lake and adjacent waters systems of Qionghai lake
