Surface water quality comprehensive evaluation method and system, electronic equipment and storage medium

The invention belongs to the technical field of surface water quality evaluation, and particularly relates to a surface water quality comprehensive evaluation method and system, electronic equipment and a storage medium, and the method comprises the steps: selecting water quality evaluation indexes of surface water; collecting a water quality evaluation index measured value; obtaining three groups of weight vectors of each water quality evaluation index by adopting a subjective weighting method analytic hierarchy process, an objective weighting method CRITIC weighting method and a projection pursuit method; obtaining a combination weight of the water quality evaluation indexes based on a game theory combination weighting method; calculating characteristic parameters of the normal cloud model, and calculating the grade certainty degree of each water quality evaluation index; and calculating the overall grade certainty degree of the to-be-evaluated water quality sample, and determining the grade of the to-be-ev
