摘要
为探明覆盖遮挡物对水体的影响,以改进后的多个20m2蒸发池作为研究对象,开展试验研究和理论分析,研究苯板的防蒸发效果和对水体的影响。研究表明:蒸发消减率随苯板覆盖率增加而增大,蒸发越强烈的月份(6-8月)蒸发消减率越高,其中8月的蒸发消减率为:26. 07~99. 83%;水体月蒸发量变化规律类似于"开口向下的抛物线",7月出现极大值210. 91(无覆盖);水面100%覆盖苯板时,水体矿化度和浊度相比无覆盖时明显降低,分别降低25. 99%和69. 17%。
In order to find out influence of floating shelters on water body,the improved 20 m^2 evaporation pools were applied to study the evaporation prevention effect of polystyrene and its influence on water body by experimental study and theory analysis.Research suggested that evaporation subtractive rate increased with the increase of the coverage rate of polystyrene board,the stronger evaporation was in June to August,the higher evaporation reduction rate was in August,the evaporation reduction rate was 26.07% ~ 99.83%.The variation of water surface monthly evaporation was similar to a downward opening parabola,the maximum value of July was 210.91( without covering).When water was covered 100% by polystyrene board,the salinity and turbidity of water body were significantly reduced 25.99 % t and 69.17%,respectively.
