根据鞍山市台安径流试验站1999年实测数据资料,分析了温度、湿度、风速、日照等对潜水蒸发的影响,并对变化规律进行了研究和探讨。分析结果显示:在其他条件相同时,温度越高,热动力增大,潜水蒸发量就越大;潜水蒸发受降水影响在地下水埋深小于1.0 m范围内表现较为明显。降水期间潜水蒸发系数较小;风力是潜水蒸发量与液面蒸发量均有所增大的根本原因;空气湿度大,气压高时,潜水蒸发量及液面蒸发量要比空气湿度小,气压低时变少。
According to the measured data of 1999 in Taian runoff station in Anshan City, the influence of temperature, humidity, wind speed, sunshine and so on on the evaporation of the submersion was analyzed, and the variation rule was studied and discussed. The results show that when the other conditions are the same, the higher the temperature, the larger the thermodynamic power and the greater the latent evaporation. The influence of the precipitation on the evaporation of the submersion is more obvious when the groundwater depth is less than 1.0 m. During the precipitation period, the submersion evaporation coefficient is small. Wind power is the root cause of both the evaporation of the submersible and the evaporation of the liquid surface. When the air humidity is high and the pressure is high, the evaporation of the submersible and liquid surface is less than that of the air, Low and variable less.
