| 摘 要： | 水面蒸发是河流、湖泊、水库等水体的主要消耗项之一.采用五道沟实验站1964-2009年观测资料,分析了水面蒸发量年际和季节变化特征及其与气温、相对湿度、日照时数、水汽压力差等各气象要素的相关关系,并提出五道沟实验站水面蒸发量的月经验公式.结果表明:水面蒸发量下降速率约92.9 mm/(10 a),水面蒸发量与气温、地面温度、水汽压力差相关关系很好,与日照和相对湿度的相关关系较好,与风速和降水的相关关系不太明显,这为进一步研究淮北地区气温升高而水面蒸发减少的悖论现象提供初步成果. |

| Abstract: | Water evaporation is a main water consumption in the rivers,lakes,reservoirs and other water bodies.Through the series of experimental data in Wudaogou Experiment Station between 1964 and 2009,this paper analyzesannual changes and seasonal changes of water evaporation,and analyzes the correlation between water evaporation and the meteorological factors including temperature,relative humidity,sunshine hours,difference in water vapor pressure,etc.Meantime,monthly empirical formula about water evaporation is d... |
