防蒸发材料局部覆盖干旱区平原水库节水试验研究

内陆干旱区水库蒸发量大,对新型防蒸发材料的研究有利于减少无效蒸发提高水库的有效利用率。通过防蒸发材料覆盖部分库面试验,统计完整周期内不同气象条件下防蒸发材料的有效覆盖面,根据影响防蒸发因子出现的概率,计算其有效防蒸发量,验证其节水效果。以内陆干旱区某一典型平原水库为现场试验对象,依据试验初步成果,对上述问题进行了探讨。

Experiment on water saving of plain reservoir of covering part of anti-evaporation materials in arid area

Aimed at the phenomenon of too much evaporation of reservoir in inland arid area,the paper carried out the research on new anti-evaporation materials,which is beneficial to reduce invalid evaporation and improve the effective utilization of reservoirs. Through covering part of reservoir and figuring out the effective coverage of evaporation materials under different meteorological of full period,then according to the probability of anti-evaporation factors,it calculated the effective anti-evaporation capacity and verified the effect of water saving. Taking some reservoir in inland arid area as an experimental object,the paper only probed the problems that had experienced above.
