摘要
潜水蒸发是四水转化中的重要环节,也是地下水消耗的主要途径。利用历年的降雨入渗补给资料,分析了降雨量、地下水埋深和土质等因素对降雨入渗补给的影响入渗补给过程,论述潜水蒸发与地下水埋深和土质的关系;潜水蒸发与水面蒸发的一致性。在潜水蒸发实验中,潜水蒸发常常出现负值,详细分析了气压、入渗量、蒸发、蒸发筒内空气柱的高度、气温等因素对负值的影响情况。
Phreatic water evaporation is an important part of ＂four water＂ transformation, it is also the main way for groundwater consumption. Based on precipitation-infiltration recharge information of past years, the influence of rainfall, groundwater depth and soil texture on precipitation-infiltration recharge is analyzed, also the relationship between phreatic water evaporation and groundwater depth, soil texture, and consistency between phreatic water evaporation and water surface evaporation are discussed. In phreatic water evaporation experiment, negative values frequently occur. Finally, detailed analysis is devoted to the impact of air pressure, infiltration capacity, evaporation, height of air column in evaporation barrel, air temperature on the negative values.
