摘要
2009年11月至2010年8月对东牙溪水库进行4次浮游植物调查,共检出浮游植物125种,隶属6门68属;浮游植物细胞密度在6.0×103-167.1×103个·L-1之间;各点位浮游植物Shannon-Weaver多样性指数和均匀度指数评价结果显示,东牙溪水库处于贫营养到中营养水平。
The Phytoplankton in Dongyaxi reservoir were analysed for four times from November 2009 to August 2010. 125 taxa belonging to 68 genera and 6 phyla were observed. The densities of phytoplankton were between 6.0 × 10^3 perlitre and 167.1 ×10^3 perlitre. Both of Shannon - Weaver index and evenness index showed that the nutritional status of Dongyaxi Reservior was oligotrophic to mesotmphic. The water quality in the Dongyaxi Reservior was good and the protection of the drinking water source should be tightened.
