摘要
１９９１—１９９３年蛤蟆通水库水位变化对浮游植物种群的动态影响研究结果表明：１）浮游植种属数随水位下降而减少；２）浮游植物生物置随水位下降而升高，其关系式为ｙ＝２９９．４６－３．３７ｘ，ｒ＝－０．９９８；３）浮游植物多样性指数随水位降低而变小，并且与水位呈明显的相关性（ｒ＝０，９９９，ｒ＝０．９８３）。
The results of the study on the effects of change of water level to population dynamics of phytoplankton of Hamutong rsservoir in 1991-1993 are stmmarized as follows:1. The number of species decreases with level lowering.2. The biomass increases with level lowering and the correlation formula is:Y= 2.99.46 - 3.37X r = - 0.8883. The diversity index decreases with the decline of water level, and significantly (r=0. 999, r=0. 983 ) correlated with the changes of water level.
