中文摘要	针对干旱区平原水库水深小、水面积大,无效蒸发损失严重的问题,本研究选用PE浮球覆盖水面来减少平原水库的无效蒸发.通过观测分析一整年的气象数据及不同风速下浮球的润湿率,对浮球润湿率与风速、覆盖面积之间的关系进行定性分析,同时建立浮球覆盖条件下水面的蒸发抑制率和防蒸发量计算模型,进而求出不同覆盖面积下浮球的年防蒸发量和年节水率.结果表明,浮球覆盖面积为1、2、3、4m~2时,节水效率分别为62.93%、65.16%、67.77%、70.00%,其中非冰冻期节水效率分别为62.21%,64.51%、67.18%、69.46%,冰冻期节水率均为91%.可见,浮球抑制水面蒸发效果显著,可有效提高水资源利用率.
英文摘要	To slove the problems of small water depth,large water area and ineffective evaporation loss to the plain water reservoir in arid area,the work presented in this study used PE spheres covering of water to reduce invalid evaporation.The relationships between the wetting rate of spheres and wind speed and coverage area were analyzed qualitatively by the means of observing and analysing the meteorological factors for a whole year and the wetting rate of spheres under different weather conditions.Meanwhile,established the evaporation inhibition rate and the evaporation capacity calculation model to obtain the annual evaporation capacity and annual water-saving efficiency of spheres under different coverage area.The results show that the annual water-saving efficiency reach up to 62.93%,65.16%,67.77% and 70.00%,respectively when the coverage area are 1m~2,2 m~2,3 m~2 and 4m~2.The water-saving efficiency of the non-freezing period are 62.21%,64.51%,67.18% and 69.46%,and the water-saving efficiency of the freezing period are all 91%.It can be seen that the spheres have remarkable effect on water evaporation and it is significant to improve the effective utilization rate of water resources.
