Abstract
This paper focuses on the dynamic variation of groundwater level in Lhasa city. According to the data, the obvious characteristic of the groundwater level of the city is that it is changing seasonally. Lhasa is divided into three districts according to hydrogeological conditions: the alluvial plain of the Lhasa-river, the alluvial plain of the Doilung-river, and the alluvial fan of intermountain, which presents a downward trend, a slight upward trend and basically stabilizing trend over the years individually. The analysis indicates that meteorological and hydrological factors lead to the obvious dynamic change of the groundwater level. However, more and more human activities and over-exploitation of the groundwater cause the downward trend in the groundwater level.
