摘要
对迪那河五一水库水温结构类型进行判别,用经验公式法对水库水温及下泄水温进行预测,并对其进行分析。结果表明:水库各月的月平均水温在45m水深以下,水温保持不变,在0―45m水深范围水温变化有所不同;水库下泄水温在4月至10月恒为7.5℃,比月平均水温略低,但要低于河道水温。水库对水温有一定的调节作用,在外界气温高的阶段能抑制水温的升高,相反能抑制水温的降低。迪那河汛期时的河流泥沙及水库运行方式对水库中底层水温及下泄水温有一定的增温作用。
The author made the judgement of the water temperature structural type of the Dinahe Wuyi project reservoir,predicted the water temperature of reservoir and discharge in the experience formula method,and analyzed them.The results showed that average water temperature in every month of reservoir kept constant below 45 meters of water,there are some differences of water temperature change between 0 and 45 meters in depth of water.The discharge water temperature in reservoir keep 7.5℃ from April to October,which was a little lower than the average water temperature in every month,but is lower than the water temperature in the river.Reservoir can make some adgustment to water temperature,which can restrain the reduction of water temperature,when Dinahe was experiencing flood season,the river silt and the operating way of reservoir played an increasing temperature role in water temperature of middle-bottom and discharge water.
