Study on Groundwater Vulnerability Assessment of Rural Centralized Drinking Water Source

In the rural groundwater centralized water supply source vulnerability evaluation process, there are many difficulties in reflecting the process of fuzzy, uncertainty, and other issues. To solve these problems, this paper constructs a groundwater vulnerability evaluation model based on variable fuzzy theory. Taking the vulnerability evaluation of Huangqipu water supply sources as an example, the hierarchical analysis method was adopted to evaluate the water source from the perspectives of natural vulnerability and social vulnerability of the water source, respectively, and 13 first-level indexes were finally selected to construct the ecological vulnerability evaluation index system. The index system was evaluated qualitatively and quantitatively. The results show that the Huangqipu water source has high vulnerability and tends to be highly vulnerable. It is recommended to strengthen water quality monitoring and realize large-scale water supply as early as possible in areas with poor groundwater quality to ensure the safety of villagers’ drinking water.
