Objective:The current over-exploitation of deep groundwater resources in some areas of the study area has led to ground subsidence,and some of the groundwater has lost its original function due to the deterioration of water quality caused by pollution.To identify the status of groundwater quality and to provide an improtant theoretical basis for the rational use of groundwater resources.Methods:The quality of groundwater in the study area was comprehensively evaluated by using the single-factor evaluation method and the comprehensive evaluation method,and the development potential of groundwater in the study area was evaluated by using the amount of resources.Results:The results of the evaluation showed that there was no excellent grade water in the area,and the poor grade and the following categories of water were predominant,and there were also different degrees of exceedance of TDS,Na+,pH,Cl-and F-.At present,there were different levels of groundwater exploitation in the area,and the analysis showed that the development potential of the study area was generally small,and in order to meet the normal water use and irrigation in the area,it is necessary to combine groundwater and surface water.Conclusion:This study proved the amount of underground water resources in Dangshan County,and provided a scientific basis for recharging Dangshan County with high-standard water for farmland and domestic use.
