【摘要】 为研究密云水库表底层水体交换试验中表层水体温度的变化及流速的变化,利用水泵将水库的底层水抽至水面,进行交换试验。结果表明,通过试验,表、中层水体的温度有所下降,温度降低会抑制表、中层水体中藻细胞的繁殖速率。试验中水泵附近的水体处于紊流状态,会破坏藻类的生长环境,对水华的发生将起到一定的抑制作用。更多还原

【Abstract】 To study the variety of temperature and flowing velocity of surface water in the experiment of exchange between surface and bottom water in Miyun Reservoir, the bottom water was bumped to the surface for the exchange experiment. The results indicated that the temperature of the surface and middle-level water in reservoir dropped, and then it could inhibit the birth rate of algae cells. During the experiment, the water was in the state of turbulence, which could destroy the growth environment of algae, and to some degree, would restrain the eutrophication in reservoir.更多还原
