The present invention discloses a pipeline water quality risk evaluation method based on a water supply network dynamic model. Establishing a water supply network dynamic waterpower and water quality model and performing accurate checking of the water supply network dynamic waterpower and water quality model through determination of the classification type and the evaluation indexes of the pipeline water quality risk; determining the weight of each evaluation index through adoption of the analytic hierarchy process; and dividing the grading standard of each evaluation index parameters based on the state data samples of the pipe network dynamic model, determining the degree of membership of each evaluation index, performing the fuzzy comprehensive evaluation, and determining the grade of the water quality risk of each pipeline in the pipe network. Though the steps mentioned above, all the pipelines of the whole water supply network are subjected to water quality risk evaluation, and the comparison and the ordering are performed according to the evaluation result to determine risk degree ordering of water quality changing and provide decision support for the management and maintenance of the pipe network; and moreover, the pipeline water quality risk evaluation method based on the water supply network dynamic model overcomes the defects that other evaluation methods are simple in index and do not take incomprehensive consideration, and the evaluation result is more reliable to ensure the accuracy and the life cycle of the evaluation.
