摘　　要：从气象要素和水体表观特性要素两大方面着眼,利用风洞开展正交实验,考察7种不同因素对蓄水屋面被动蒸发效果的影响。研究发现,太阳辐射对蒸发的影响最显著,其次是水深、水面污染程度和水面浅色漂浮物覆盖率,而环境空气温度、相对湿度和风速的影响较弱。高太阳辐射照度、中等水深、干净水面、一定覆盖率的水面浅色漂浮物、高温、低湿、中等风速最有利于促进蒸发。Watching from two major aspects of meteorological elements and apparent characteristics of water bodies, the orthogonal experiment was carried out using wind tunnel to investigate the influences of seven different factors on passive evaporation effect of water-ponding roof. The research finds that the influence of solar radiation on evaporation is the most significant, followed by water depth, water pollution degree and coverage rate of undertint floater on water surface, while the influence of ambient air temperature, relative humidity and wind speed was weak. Strong solar radiation intensity, medium water depth, clean water, certain coverage rate of undertint floater on water surface, high temperature, low humidity and moderate wind speed are the most propitious to promote evaporation.
