摘要
1991～1 993年水位变化对水库浮游动物种群动态影响的研究结果表明 :1 浮游动物种属数随水位下降而减少 ;2 浮游动物生物量随水位变化而变化 ,关系式为y =- 82 69+1 0 0 9x ,r=- 0 842 ;3 浮游动物多样性随水位降低而变小 ,与水位呈明显的相关性 ,r=0 976,r=0 958。
The effect of water level changes on the stock developments of zooplankton in Hamatong reservior in 1991-1993 demonstrated as follows: 1.The number of zooplankton reducted with the lowering of water level; 2.The biomss of zooplankton changed with changing of water level,and correlation formula is Y=-82 69+1 009x,r=-0 842; 3.The diversity index of zooplankton decreased with the decline of water level,and significantly(r=0 976,r=-0 958)correlated with the changes of water level.
