摘要
以大通南塌陷塘为主要研究对象,通过为期一年的采样、监测,鉴定出浮游动物123种,共计75个属,主要优势种为臂尾轮属和秀体溞属,得出该塘由八十年代以寡营养型针眼虫为优势种转变为现以臂尾轮属的优势种,在一定程度上说明塌陷塘有机污染的加重。本研究可为矿区塌陷塘生态环境状况的改善提供理论基础。
The study object is Datong south subsidence pool. By a one-year sampling and monitoring, a total of 123 kinds of zooplankton,belonging to 75 specieses were identified, the dominant specieses are Brachionus and D. leuchtenbergianum. In the pool Brachionus and D. leuchtenbergianum are dominant species instead oligotrophic pinhole worms in the eighties of 20^th century. It explained to a certain extent, that organic pollution get worse. The study providesa theoretical basis for ecological environment improvement of coal mining subsidence area.
