Abstract In order to objectively and accurately evaluate the implementation effect of water-saving reno-vation projects in large-scale irrigation areas, the implementation effects of water-saving renovation projects in large-scale irrigation areas are divided into four grades: excellent(Ⅰ), good(Ⅱ), mo-derate(Ⅲ)and poor(Ⅳ). There are 5 first-level indicators, 12 second-level indicators and 35 third-level indicators for the degree of standardization, construction tasks and investment completion, realization of benefits, management and reform, and sustainable development of irrigation districts. A comprehensive evaluation index system for the implementation effect of water-saving transformation in large irrigation areas was established. A comprehensive evaluation cloud model for the implementation effect of large-scale water-saving renovation projects in irrigation areas was established by using the game theory comprehensive weighting method to calculate the combined weight of evaluation indicators. Taking a large-scale irrigation area water-saving renovation project in Hubei Province as an example, it is verified that the comprehensive evaluation result of the irrigation area has a membership degree of 0.531 6 for excellent. It shows that the comprehensive evaluation of the implementation effect of water-saving transformation in the irrigation district is excellent, and the evaluation result is basically consistent with the actual situation of the irrigation district, and the evaluation result of the model is more scientific and accurate, which can provide a basis for the construction and management of large-scale water-saving transformation projects in the irrigation district.
