Abstract

With the systematic promotion of sponge city construction in China to alleviate the water resources management challenge, the groundwater level and water quality in the Beijing area have improved significantly. Since the demonstration construction of Sponge City was promoted in 2015, the groundwater level in Beijing has ended the downward trend of over 15 m continuous decline for nearly 20 years. At the same time, natural infiltration and natural purification also effectively ensure the water quality of rainwater infiltrating into the ground. With the rise of the groundwater level, although many underground buildings in Beijing will face new risks, the remediation of the groundwater level is still of great significance to alleviating the phenomenon of urban surface subsidence and ensuring urban water resources.
