Abstract

A rating evaluation method for groundwater pollution source intensity, including: determining pollution source characteristic indices, and weights and scores thereof, according to the type, the discharge mode, the existence time, and the like of a groundwater pollution source; determining an vadose zone antifouling property index and an vadose zone vulnerability index and scores thereof according to vadose zone characteristics; determining a rating evaluation index system for groundwater pollution sources by combining the pollution source characteristic indices with the vadose zone antifouling property index and the vadose zone vulnerability index; and establishing a rating evaluation method for groundwater pollution source intensity and evaluating the groundwater pollution source intensity. The evaluation method comprehensively considers pollution source characteristics and vadose zone characteristics to accurately reflect source intensities of groundwater pollutants and protect groundwater, and may provide a scientific basis to allow for more scientific and rational protection and management of groundwater.
