从地下水研究意义出发,综述了地下水研究现状,利用含水层结构对研究区进行离散剖分。利用观测资料确定潜水蒸发与地下水的关系,在界定初始地下水位的基础上,利用该关系模型对初始潜水蒸发空间化,结果表明,初始潜水蒸发(1990年7月)分布在7～80mm之间,高值出现在研究区的河岸地带,低值出现在研究区的北部、南部和远离河岸区。研究区的潜水蒸发随着时间的变化也有显著的变化,一般在6—9月蒸发量较大。
Based on the significance of groundwater research, the status quo of groundwater research is summarized, and the aquifer structure is used to discrete the study area. Based on the observation data, the relationship between submersible evaporation and groundwater was determined. Based on the initial groundwater table, the initial submersion evaporation was spatialized by using the relational model. The results showed that the initial submersion evaporation (July 1990) was between 7 ~ 80mm , The high value appeared in the study area of the river bank, the low value appeared in the study area in the north, south and away from the riverbank area. Submersible evaporation in the study area also changed significantly with time, generally larger evaporation in June-September.
