Objectives of the study
Groundwater is the main water source in North China. The North China has suffered a cumulative groundwater deficit of 1800 billion m3 due to large-scale groundwater exploitation, which is particularly prominent in the Beijing, Tianjin and Hebein. In order to systematically solve the problem of groundwater overdraft in North China, the government has continuously issued relevant policies since 2014. In North China, the study on dynamic response law and mechanism of groundwater level under the influence of overmining treatment has become a research hotspot.This paper studied the evolution of groundwater dynamic in the North China Plain after the implementation of overdraft treatment measures in recent years, which provided a basis for scientific evaluation of groundwater response and policy research under groundwater overdraft management in North China.
