为了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1.83×104~51.1×104cells/L,生物量变化在0.03~0.60mg/L;浮游动物80种,密度变化在2.16~76.34个/L,生物量变化

　　To evaluate tropic state and biotic community of the main staeam 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-Weaner 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 1.83×104to 51...
