摘　　要：为了探讨潜水蒸发规律,为水资源评价提供依据,根据河南省惠北试验站地下水量均衡观测试验场内同一时期不同潜水埋深、不同土壤质地及有无种植作物的测筒试验,通过对潜水蒸发影响因素及其规律的探讨,得到潜水蒸发与气象因素、地下水埋深、上壤质地等影响因素之间的关系。并利用柯夫达公式分别计算出在不同土质下有无种植作物的潜水蒸发量。由于考虑因素更多,故比以往用单一值计算潜水蒸发量的精度更高。In order to probe the rule of phreatic water evaporation and to provide basis for water resources evaluation, based on the experiment of e-vaporation observation with different groundwater tables, soil textures and under conditions of with or without crops in the groundwater balance site at Huibei Experiment Station in Henan Province, the relationships between evaporation and meteorological factors, burial depths of groundwater table, and soil textures are proposed through analyzes on these influencing factors of phreatic water evaporation. The Equation of Kefuda is used to calculate the phreatic water evaporation under the conditions of with and without crop for soils of different textures. Due to consideration of multiple factors instead of single factor, the precision of calculation of the phreatic evaporation is higher than that of single factor method.
