摘要
2006年8月至2007年3月分4次对蓬溪县赤城湖进行了藻类植物定性和定量的采集,共设置11个采样点:渡口、库闸、抽水站、湖心(1)、团结桥、金仙寺、清幽岛、船舫岛、新堰坎、农家乐和湖心(2)。通过分析各采样点藻类植物种群组成,了解到赤城湖有4个着生藻类群落,即鞘丝藻-席藻-颤藻群落(Lyngbya-Phormidium-Oscillatoria community)、伪枝藻群落(Scytonema community)、鞘藻群落(Oedogonium community)、转板藻-双星藻-水绵群落(Mougeotia?Zygnema-Spirogyra community)。赤城湖的着生藻类群落指示的水质在Ⅴ、Ⅵ、Ⅶ带之间,反映出的水质状况为δ-、β-、γ-中污带水质。
To analyze the quantity and quality of the algae existed in Chicheng Lake in Pengxi County,the researchers have set up 11 sampling points： the ferry,dam gate,pumping station,the center of the lake（1）,Tuanjie bridge,Jinxian temple,Qingyou island,Chuanfang island,Xinyan candela,a Farm and the center of the lake（2）（the sample number 1,2,3,4,5,6,,7,8,9,10,11）.There are four times of investigation in Aug.28th,Nov.28th in 2006 and Feb.2nd,Mar.28th in 2007.Based on the analysis of the constitution of the Algae community in every sampling point,the researchers find that there are 4 attached algae communities： Lyngbya-Phormidium-Oscillatoria community,Scytonema community,Oedogonium community and Mougeotia-Zygnema-Spirogyra community.The researchers also find that the water quality of Chicheng Lake indicated by algae communities is between Ⅴand Ⅶ band,which shows that the water quality is δ-、γ-、β-mid-contaminated.
