摘要
2006年以桃-阿海子和红碱淖尔湖泊为主要研究监测对象,利用镜检分析方法,对2个湖泊的浮游植物、浮游动物及底栖动物的种群特征进行了调查;水生生物多样性指数采用Shannon-Wiener指数计算.结果表明:红碱淖尔检出浮游植物14种,桃-阿海子4种.根据生物多样性指数水质评价标准,红碱淖尔湖水达到中等污染程度,桃-阿海子湖水是重污染.红碱淖尔检出浮游动物8种,轮虫密度最大,轮虫和枝角类的生物量占绝对优势;桃-阿海子检出9种,原生动物密度最大,枝角类生物量最大.红碱淖尔底栖动物共发现9种,全部为水生昆虫幼虫;桃-阿海子在浅水区未发现任何底栖动物,水生生物以耐盐种和喜盐种为主.2个湖泊水生生物种类少,优势种突出,主要是环境因素造成的.红碱淖尔水体盐度为5.81 g·L-1,pH值为9.25,正好处于水生生物耐盐性极限(5.00～8.00 g·L-1盐度)的范围内,在高pH值的协同作用下,只有少数生物能够适应这种环境条件.
Erdos salina wetland borders on Kubuqi Desert and Maowusu Desert.It is a wetland of international importance to protect Larus relictus and its habitat.Hydrophily biology has sensitivity on circumstance change.The study is on Tao-A Haizi and Hongjian Nur in 2006.The survey measured according to Investigation Handbook of Fisheries Natural Resources in Inland Waters.Hydrophily biology diversity index was calculated by Shannon-Wiener.After checking,it was found that there were 14 kinds of phytoplankton in Hongjian Nur and 4 kinds phytoplankton in Tao-A Haizi.There were 8 kinds of zooplankton in Hongjian Nur and 9 kinds in Tao-A Haizi.There were 9 kinds of zoobenthos in Hongjian Nur and none in Tao-A Haizi.Hongjian Nur is middling pollution and Tao-A Haizi is severely polluted according to diversity index.
