Abstract: In the context of rural revitalization and ecological civilization construction, a three-dimensional model is constructed to evaluate the ecological level of rural infrastructure systems in order to better meet the practical needs of rural infrastructure systems in terms of ecological construction and ecological evaluation. The model constructs an ecologization evaluation system for rural infrastructure systems from three perspectives: development status, regional level and development trajectory, including three first-level indicators and 15 secondlevel indicators. Hierarchical analysis method, fuzzy comprehensive evaluation method, and Delphi method are adopted, aiming to systematically and objectively evaluate the ecologization of rural infrastructure systems. Finally, an empirical analysis is conducted using the rural infrastructure system of Shixia Village in Badaling Town, Yanqing District, Beijing, as an example, to prove the scientificity, rationality, and feasibility of the evaluation method, and to put forward a strategy for upgrading the ecologization of the rural infrastructure system, with a view to proposing a referenceable method for the modernization of the rural infrastructure system.
