摘　　要：本文研究了摇蚊幼虫对底泥中氮、磷释放的影响，初步探讨了摇蚊在湖泊富营养化过程中的生态作用。结果表明，摇蚊幼虫能明显促进底泥中氮、磷的释放，而释放到水层中的氮、磷又容易被藻类吸收利用，从而促进藻类生长。这种生态效应与水体营养循环和富营养化的发生及发展过程间存在着重要的关系。The ecological functions of chironomids on the development of lake eutrophication were studied through examining the influence of chironomid larvae on nitrogen and phosphorous release in sediment. The results showed that chironomid larvae stimulated visible algal growth by increasing nitrogen and phosphorous release from sediment to overlying water. There is an important relationship between such an ecological function and the development of lake eutrophication.
