摘要：

In order to select highly representative and sensitive indicators for water supply network health status evaluation, 11 water supply network health status evaluation indicators were analyzed by hierarchy process, and the contribution calculation and sensitivity analysis were carried out based on factor analysis method. The results of analytic hierarchy process show that the evaluation system includes external environment influencing factors on the static structure of the pipeline, internal static structure influencing factors of the pipeline, water quality influencing factors and hydraulic influencing factors. The results of contribution and sensitivity analysis show that the eight indicators of inner and outer lining, pipe diameter, ratio of node flow to total flow, residual chlorine, ratio of node pressure to minimum service pressure, soil cover thickness, pipe material and pipe age should be taken as the basic required indicators, and the data accuracy of inner and outer lining, pipe diameter, ratio of node flow to total flow, residual chlorine, soil cover thickness and pipe age should be improved as much as possible. © 2021, Editorial Board of Water Resources Protection.
