神农架林区大九湖水生生物调查

Survey of Aquatic Life (Zooplankton, Phytoplankton, Benthos) in Shennongjia Dajiuhu Lake

摘要: 6年来，我们用NE930辉煌光学显微镜、迅数藻类分析系统联合成像，在浮游动物调查方面共检测出原生动物7属，轮虫6属，桡足类2科(受仪器条件限制)，枝角类5属；浮游植物调查方面共检测出8门，61属(未细分到种)；底栖动物调查方面共检测出4科。通过6年来的调查研究，我们发现浮游植物优势属和水温、水质类别有一定的关系。

Abstract: In the past 6 years, 5 Genera of protozoans and 6 Genera of rotifers have been detected in zoo-plankton survey by using the combination imaging of NE930 brilliant optical microscope and rapid digital algae analysis system, one family of Copepoda (restricted by instruments, Copepoda is subdivided into Genera and cannot be subdivided into Genera by ordinary optical microscope), 5 genera of Cladocera; 7 Phyla and 54 Genera (not subdivided into species) were detected in phyto-plankton survey; Four families were detected in Benthic fauna survey. Through 6 years’ investiga-tion and study, we found that the dominant genus of phytoplankton and water temperature, water quality category has a certain relationship.
