为了解湘江干流水质与生物群落现状,2010-2011年对湘江的水质和浮游生物的分布进行了采样分析,利用香农-威纳多样性指数分析湘江干流浮游生物群落特征,并结合水质理化指标评价其水体营养状态。结果表明,共检出浮游植物8门99属164种,丰度变化在(1.83-51.1)×10~4cells/L,生物量变化在0.03-0.60 mg/L;浮游动物80种,密度变化在2.16-76.34个/L,生物量变化在0.01-1.95 mg/L。各采样点的浮游植物多样性指数变化在2.47-5.43,浮游动物多样性指数变化在1.63-3.38,浮游生物的多样性较好,显示出湘江干流的浮游生物群落处于较稳定的状态。对湘江βm-αm指示种种类组成和群落结构分析,结果显示湘江水体属于中...

To evaluate tropic state and biotic community of the main stream of Xiangjiang River, the water quality and plankton distribution were sampled and analyzed from 2010 to 2011. The plankton community characteristics of Xiangjiang River were studied via Shannon-Wiener index, and nutrient level was assessed in association with physicochemical index of water quality. The results showed that, a total of 164 species of the phytoplankton belonged to 99 genus; the total cell density varied from 1.83×104 to 51.1×104 cells/L; the biomass ranged from 0.0...
