Groundwater Utilization and Countermeasures of Groundwater Overexploitation in the Yangtze River Basin
The utilization and development of groundwater in the Yangtze River Basin remain relatively limited.Nonetheless,groundwater resources continue to play an essential role in preserving the ecological balance of rivers and lakes,addressing sudden water safety challenges,and supporting agricultural production.Drawing on groundw-ater exploitation and stage data from 2011 to 2020,we examined the current status and trends in groundwater utili-zation,stage variations,and the issue of over-exploitation in the Yangtze River Basin.Our findings reveal that shal-low groundwater serves as the primary source of extraction in the basin,with a gradual decline in overall extraction levels.With few exceptions,groundwater stages across the basin have demonstrated stability or a modest increase.Over the period from 2011 to 2020,area of over-exploitation were predominantly concentrated in Nanyang City,Henan Province,where groundwater stages exhibited a declining pattern.This underscores the urgent need for the implementation of alternative water source projects to mitigate irrigation water shortages.
