摘　　要：为了掌握近年来镜泊湖水质污染变化情况对水生生物的影响,笔者于2008年4月至2009年10月,采用张网捕获和彼德生采泥器采集法,对镜泊湖水生动物生物多样性进行了调查。结果发现,野生鱼类的种类和数量都在逐渐减少,浮游动物的数量也随着水污染程度发生着相应的变化。最后,笔者对水生动物生物多样性降低的原因进行了分析,并提出了保护镜泊湖动物生物多样性的几种途径。In order to have a good grasp of the influence of the change of water quality on aquatic animals in Lake Jingbo,a survey of biodiversity of aquatic animals was conducted from April 2008 to October 2009.Samples were collected by stow net and Petersen grab.The results showed that the species and quantities of wild freshwater fish were gradually decreased,and the quantity of zooplankton also changed with the pollution level.In present artiale,the decline cause of aquatic animals biodiversity was also analyzed,and the countermeasures to protect aquatic animals biodiversity were put forward.
