摘要
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。
There is little precipitation in the lower reaches of Heihe River.The groundwater level determines the pattern and distribution of vegetation,a highly valuable resource to animals and with important role in eco-environment.Based on the field investigation of geology and hydrogeology,a three-dimensional aquifer system（45 312 cells and 3 slices）was constructed.Evaporation of groundwater is a key outlet which drops the groundwater level.The relationship between the groundwater level and groundwater evaporation was built as：E = C0 e-a D.The spatial distribution of the initial groundwater level was obtained by interpolation,and then the initial spatial distribution of evaporation was calculated according to their relationship.The study lays a foundation for modeling spatial and temporal distribution of the groundwater level in the study area.
