【摘要】:为减少蒸发造成的干旱区平原水库水量损失,进行了苯板覆盖水面消减蒸发的节水试验。试验分别采用蒸发池面积的25%、50%、75%、100%的苯板覆盖水面以探析不同面积条件下苯板对蒸发的消减规律。结果表明,不同面积苯板覆盖条件下,分别减少了23.85%、39.63%、55.54%、63.85%的蒸发水量。为探索苯板实际应用的可行性,在水库进行了实际铺设研究。研究表明,苯板在合理铺设的情况下,可以抵抗一定风浪作用,进而达到消减平原水库无效蒸发的目的。本实验对提高干旱区水资源有效利用率和水资源调配能力具有重要意义。
[Abstract]:In order to reduce the water loss caused by evaporation in plain reservoirs in arid area, a water saving experiment was carried out on the surface of water covered with benzene plate. In the experiment, 25% benzene plate of evaporation pool area was used to cover the water surface with 100% benzene plate in order to probe into the law of evaporation abatement by benzene plate under different area conditions. The results showed that the evaporation water amount of 23.85% 39.63% was reduced by 63.85% under different areas of benzene plate covering. In order to explore the feasibility of practical application of benzene plate, a practical laying study was carried out in the reservoir. The results show that the benzene plate can resist the wind and wave under the condition of reasonable laying, and then it can reduce the invalid evaporation of plain reservoir. This experiment is of great significance to improve the effective utilization rate of water resources and the ability of water resources allocation in arid areas.
