The current situation of water conservancy project management generally has the problem of emphasizing construction rather than file management, and the lack of reasonable file management evaluation and assessment methods is one of the main reasons. In order to innovate the means of archives management for water conservancy projects, a system consisting of organization, management system, daily management, supporting facilities and archives utilization is established to evaluate the archives management work of Fengcheng Golden Reservoir Project by using the improved fuzzy AHP method for the current problems. The results show that the project＇s archive management work scored 71.2, which means the work is qualified, but such problems in the aspects of archives staff training system,remuneration system and archive benefit development, need to be improved.
