Abstract

Groundwater plays an important role on water supply and safety in Beijing Since the south to north water diversion (the Beijing’s groundwater table has rebounded significantly Scientifically studying the key influencing factors of groundwater level fluctuation is crucial for guaranteeing the regional water supply and water source allocation Based on the in depth analysis of groundwater and water resource structure evolution, combined with (Gravity Recovery and Climate Experiment) GRACE gravity satellite, this study aimed to quantify the contribution rate of the SNWD in Beijing The results showed that the SNWD has a strong impact on the restoration and conservation of groundwater These can provides scientific and technological support for the continuous improvement of the comprehensive measurements of groundwater overdraft in Beijing
