【摘要】：針桿藻屬(Synedra)是常見的淡水藻類,飲用水源中針桿藻屬的暴發(fā)式增長會嚴重影響水廠正常運行.為明確南水北調(diào)東線調(diào)蓄湖泊針桿藻屬的時空分布特征及其與環(huán)境因子的相關(guān)性,于2011年3月—2013年5月在東線四湖(即洪澤湖、駱馬湖、南四湖和東平湖)逐月采樣進行調(diào)查研究.結(jié)果表明,監(jiān)測期內(nèi)洪澤湖、駱馬湖、南四湖和東平湖針桿藻屬密度最大值分別為442.0×104、549.3×104、301.6×104和795.4×104L-1,尖針桿藻(Synedra acus)是東線四湖針桿藻屬的優(yōu)勢種.非度量多維尺度(non-metric multi-dimensional scaling,NMDS)分析表明,東線四湖針桿藻屬的分布特征存在一定差異,東平湖和駱馬湖針桿藻屬分布特征更加相似.Pearson相關(guān)性分析(Pearson correlation analysis)表明,影響東線四湖針桿藻屬生長的環(huán)境因子主要是表層水溫、透明度、ρ(DO)和ρ(TN),其中表層水溫是最主要的影響因素.
[Abstract]:Synedraa is a common freshwater algae. The outbreak growth in drinking water sources will seriously affect the normal operation of water plants. In order to clarify the temporal and spatial distribution characteristics and the correlation with environmental factors of the genus Acetophyllum in the East Route of South-to-North Water transfer Project. Samples were collected from March 2011 to May 2013 in four lakes along the eastern route, namely Hongze Lake, Luoma Lake, Nansihu Lake and Dongping Lake. The results showed that Hongze Lake and Luoma Lake were monitored during the monitoring period. The maximum density of Phellodendron in Nansihu and Dongping Lake was 442.0 脳 104,549.3 脳 104,301.6 脳 10 ~ 4 and 795.4 脳 104 脳 10 ~ 4 路L ~ (-1), respectively. Synedra acusa is the dominant species of the genus Cladophora on the eastern route. Non-metric multi-dimensional scaling. NMDS analysis showed that there were some differences in the distribution characteristics of the genus Cladophyllum in the East Line. The distribution characteristics of the genus Acetophyllum in Dongping Lake and Luoma Lake were more similar. Pearson correlation analysis showed that the distribution was more similar. The environmental factors affecting the growth of the genus Phellodendron on the East Line are mainly the surface water temperature, transparency, 蟻 -DOO) and 蟻 ~ (2 +) -TNN, among which the surface water temperature is the most important factor.
