Abstract
As an important water resource, groundwater has been unreasonably developed for a long time in our country, causing a lot of problems. This paper combines the data from the national groundwater monitoring stations and the groundwater depth data collected locally to statistics and analysis of groundwater overexploitation across the country. Especially in key plains, through the water level variation method. The research results are compared and verified with national authoritative data such as Groundwater Dynamics Monthly Report and predecessors’ records in the literature, revealing the current key areas of groundwater overexploitation, and clarifying the importance and urgency of groundwater governance in the future. This study also put forward some suggestions of groundwater overexploitation.
Highlights
Groundwater resources play an indispensable role in social and economic development, food security, and drinking water safety
The total of overdrawn area in Inner Mongolia Autonomous Region amounts to 7,200 km2 (Wang, P. et al, 2016) [3,4,5]
A comprehensive assessment and analysis of the status of groundwater overexploitation across the country is extremely important for the sustainable development and utilization of water resources in China
Summary
Groundwater resources play an indispensable role in social and economic development, food security, and drinking water safety. As a reliable source of water supply, groundwater plays an important role in ensuring water security. In order to meet the needs of population growth and economic development, some water-scarce areas have long been over-exploiting groundwater. The continuous overdraft of groundwater has caused a series of ecological, geological, and environmental problems, resulting in the loss of economic and environmental resources [1,2]. There are many research conclusions on groundwater overexploitation areas in China. The total of groundwater overdrawn areas in Jiangsu Province is about 16,500km (Huang, X.Y. et al, 2014a). A comprehensive assessment and analysis of the status of groundwater overexploitation across the country is extremely important for the sustainable development and utilization of water resources in China
