Water Quality Assessment of Mopanshan Reservoir Based on Multiple Evaluation Methods
As the main water source of Harbin City,Mopanshan Reservoir's water quality evaluation is of great significance to ensure the safety of residents'drinking water.Five indicators of dissolved oxygen(DO),ammonia nitrogen(NH3-N),chemical oxygen demand(COD),total phosphorus(TP),and total nitrogen(TN)were selected for 12 months in 2022,and the principal component analysis method and The RBF neural network evaluation method was used to evaluate the water quality of Mopanshan Reservoir.The results show that the water quality of Mopanshan Reservoir is Grade II,which is in line with local testing results.The principal component analysis method can truly and objectively analyze the water quality of local reservoirs and provide certain reference for reservoir improvement and improvement.The RBF neural network only needs to generate the required training samples according to each water quality classification standard,and it is easier to use a well-trained computing model to evaluate water quality.The method is simple and has good practicability.This study can be used as a reference for other regions.
