吉首大学风雨湖淡水原生动物群落结构研究

目的]研究吉首大学风雨湖原生动物的群落结构。方法]通过采样设置、种类鉴定、原生动物量的检查及多样性指数（D）的计算、水体来源理化性指标检测，来确定原生动物群落结构。结果]共观察到各类原生动物44种，其中鞭毛虫14种，占原生动物总数的31．9％；肉足虫8种，占原生动物总数的18．9％；纤毛虫22种，占原生动物总数的50％。结论]风雨湖的水质污染严重，尤其是入水口水源，多样性指数（d）值很低，需要对此进行一定的处理措施。

The Investigation on the Construction of Protozoa Community for the Fengyu Lake in Jishou University

Objective]The aim was to study the constion of protozoa community for the Fengyu Lake in Jishou university.Method]The proto-zoons community of the Fengyu Lake were researched by sampling,identifying species,checking amount and diversity index of protozoa,calculating the physical and chemical indicators of water sources.Result]The results showed that a total of 44 species of protozoa were found by investigating,including 14 species of mastigophoras taking up 31.9% ,8 species of sacrodinas taking up 18.9% ,and 22 species of ciliates taking up 50% .Conclusion]The water pollution of Fengyu Lake was serious,especially in the inlet water ,the diversity index value was low which needed certain measures to deal with.
