| 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）浮游植物生物量随水位下降而升高，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）。

| Abstract: | 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. |
