摘要
针对浮球材质、大小、覆盖率等参数对抑制水面蒸发效果敏感性的影响效果,采用控制变量法及对比法设计试验,利用SPSS等软件对试验结果进行数据分析处理,并建立不同试验设计与气象因素之间的联系模型。结果表明:浮球不同材质、大小、覆盖率等参数不同,会直接影响其覆盖水面的蒸发量对气象因素的敏感性。其中,覆盖率影响最为明显,相同覆盖率条件下浮球直径增大会提高抑制水面蒸发效率,材质对抑制蒸发的影响相对较弱。浮球的抑制蒸发作用主要是通过遮蔽太阳辐射直射水体和阻碍风对水面的吹拂作用得以体现。
In order to explore the influences of the material,size and coverage rate of floating ball on the effect of inhibiting water surface evaporation,the tests are designed by using control variable method and comparison method.The SPSS and other software are used to analyze test results,and the connection model between different test parameters and meteorological factors is established.The results show that the sensitivity of water surface evaporation to meteorological factors is directly affected by the differences of material,size and coverage of floating ball.The effect of floating ball coverage is the most obvious.Under the condition of same coverage,the increase of floating ball diameter will improve the efficiency of inhibiting water surface evaporation,while the effect of materials on inhibiting evaporation is relatively weak.The evaporation inhibition by floating ball is mainly reflected by shielding direct solar radiation on water surface and obstructing wind blowing over water surface.
