摘要
本文初步分析了东太湖及其网围养鱼区的底栖动物的种类组成、数量、生物量、多样性及其分布特点;选用三个生物数量指标:Good—night指数、King和Ball指数以及颤蚓类密度。运用系统模糊聚类方法,对网围养鱼区的环境质量作出初步评价和区划;论述了在东太湖适当地开展网围养鱼并控制其规模的必要性,对如何控制网围养鱼所造成的污染提出初步建议,供有关部门参考。
By investigationg the benthon inhabited in the eastern Taihu lake and its pen fishfarming area, we analysed prelimilarily their composition, abundance, biomass and diversity as well as their distribution. Selecting the three bio-quantity indexes, i. e., the Goodnight Index, the King and Ball Index and the Density of Tubificidae, we give a primary assessment and division of the environment quality in the pen fishfarming area. The necessity has been expounded that we should carry out properly and control pen fishfarming. The first advice has been put forward that is how to control the pollution caused by pen fishfarming.
