Abstract: Considering the application of traditional evaluationmethods, in the evaluation of low-pollution water purification effect under thebackground of river wetland water ecological restoration, there is no calculationof multi-layer geological purification effect relation between low-pollutionwater, so the evaluation vector of purification effect is low. To this end, anew method for evaluating the purification effect of low-pollution water underthe background of river wetland water ecological restoration was designed.First, the least square method was used to obtain the purification effectparameters of low-pollution water in the survey area, and the final resultswere fitted to determine the purification effect parameters of low-pollutionwater. Then, the purification effect relation between multiple layers oflow-pollution water is calculated to ensure that the calculation result iswithin the adjustable range of river wetland water ecological restoration.Then, the evaluation factor ｌｏａｄ matrix is constructed to satisfy thecomprehensive evaluation of data. Finally, the evaluation of the purificationeffect of the low-pollution water was given and scored to complete the evaluationof the purification effect of the low-pollution water. Experiments weredesigned, and the results showed that the evaluation vector of the purificationeffect of the designed evaluation method was significantly higher than that ofthe control group, which could achieve accurate evaluation of the purificationeffect of low-pollution water.
