| Abstract: Based on the connatation of sustainable development, the comprehensive benefit evaluation index system of water saving reform in irragation area has been provided in five aspects, society, resources, economic, technology, and ecological environment. It combined goals evaluation and relative literature. It built the projection pursuit model to improve comprehensive evaluation, and used particle swarm optimization optimization and its project direction. Water saving reform benefit could be scientifically evaluated according to the project values. It showed that the technology avoided the subjective determination weight by experts and the results are objective and accuarate, if the method was used in the water saving reform projection benefit evaluation in Guangzhong large-scaled irragation area. The mothod was basic and provide a new way for comprehensive reform evaluation. |
