摘要
2003年7月到2004年6月对董铺水库的浮游生物进行了调查，对其种类组成、生物量、种群数量、污染指标种等相关指数进行了初步分析，得出结果是综合指数为1．46，种群数量为2．256×10^5个／升（浮游植物），多样性指数的值在3．01．3．22之间。这些指数表明：目前董铺水库的水质仍属清洁水体，从营养水平来看处于贫营养与中营养之间，并向中营养水平演化，水质存在着向轻度污染转化的趋势。
The seasonal changes in the ecological feature of plankton including species composition, population, saprobic indicators,mulfiple index etc were studied at 5 sampling stations in Dongpu reservoir from July 2003 to June 2004. In Dongpu reservoir, the comprehensive index is 1.46, the mean density of phytoplankton reached 2.256 × 10^5 individual per litre, and the multiple index varied between 3.01 and 3.22. All these indicated that Dongpu reservoir was regarded as a mid-eutrophication reservoir with fresh water, it also varied from poor nutrition to mid-nutrition from the nutritional level. It might be changed into little polluted ff people do not pay more attention to protect it.
