Abstract: The standardized management of reservoirs plays a crucial role in improving the operational efficiency of reservoirs, safeguarding the lives and property of people downstream, and fulfilling the requirements of farmland irrigation. According to the content and characteristics of reservoir standardized management, and considering the basic situations of seven large and medium-sized reservoirs in Dangyang City, including Gonghe Reservoir, Yangshuhe Reservoir, Paoma Reservoir, Guandaohe Reservoir, Sanxingsi Reservoir, Liujiachong Reservoir, and Xiangjiacao Reservoir, an evaluation index system for reservoir standardized management is constructed from five dimensions: engineering status, safety management, operation and maintenance, management support, and informatization construction. The Analytic Hierarchy Process (AHP) is employed to determine the weights of each indicator, enabling a quantitative analysis of the standardized management levels of these reservoirs.
