Abstract:

于2011年1、4、7月份对艾溪湖的浮游藻类进行取样调查.研究表明:艾溪湖水体中共发现藻类6门,40属;其中绿藻门种类最多,有19属;其次是蓝藻门和硅藻门分别为9属和8属.浮游藻类的细胞密度变化从62.45×106~395.52×106个/L,平均数量为209.76×106个/L;冬、春两季优势种类为绿藻门的栅藻属;夏天则为蓝藻门的平裂藻,占总藻类数的77.04;.多样性指数、物种丰富度、均匀度这3个指数值均表明水体已经严重污染.
The investigation of phytoplankton in the aquaculture Aixi lake was performed in 2011.A total of 40 generas and 6 divisions of phytoplankton were identified.Among,Chlorophyta was the dominant division,include 19 generas; The next dominations were followed by Cyanophyto and Bacillariophyto,with 9 generas and 8 generas respectively.The abundance of phytoplankton changed from 62.45×10~395.52×10/L,the average density was 209.76×10/L.The dominatoin species was Scenedesmus sp.and Merismopedia sp.in winter or spring and in summer respectively.Both of the index about evenness,diversity and dominant were showed that this lake had been polluted seriously
