摘要
2011年秋季对抚仙湖水域10个站位进行大型底栖动物的采样调查,研究了该湖泊湖滨带底栖动物的群落结构。共鉴定底栖动物10个分类单元,其中水生昆虫类和软体动物等主要类群分别为1种和6种,各占总物种数的10%、60%。主要优势种为拟沼螺、日本沼虾。调查区底栖动物的密度介于26～229ind/m2之间,平均值为97.9ind/m2。生物量介于0.96～15.69g/m2之间,平均值为6.77g/m2。香农-威纳多样性指数介于0～1.45之间,平均值为0.82。
Ten stations of Fuxian Lake were surveied to study the lake benthic community structure in autumn of 2011. After the analysis of the survey sample, 10 benthic taxa were identified, including Chironomidae larvae and molluscs,of which the major groups of aquatic insects and mollusks were 1,6 Respectively. The dominant species were Assimineidae and Macrobrachium nipponense. The density of benthic fauna survey area was between 26 229ind/m^2 with an average of 97.9ind/m^2. Biomass ranged from 0.96 - 15.69g/mawith an average of 6.77 g/m^2. Shannon-Wiener diversity index ranged from 0 to 1.45.
