Abstract


The paper puts forward the idea of groundwater environment health and constructs an evaluation index system for the groundwater environment health according to the connotation of groundwater environment health. The 17 evaluation indexes were simplified to obtain the most simple evaluation index system through the simplification function of the rough set, and then the weight of the evaluation index was calculated through the weight calculation function of the rough set, and the quantitative evaluation of groundwater environment health was carried out by means of a comprehensive index method. The evaluation results show that the attribute simplification and weight calculation of the rough set can be applied to the comprehensive evaluation of hydrogeology.
