ABSTRACT
The comprehensive benefit evaluation of water-saving irrigation in the irrigated areas is a complex and dynamic evaluation system. According to the characteristics of randomness and fuzziness of the system, an optimized cloud model algorithm for the comprehensive benefit evaluation of water-saving irrigation in the irrigated areas was constructed, and the calculation of the weight cloud model was optimized. At the same time, taking Yahekou as the research area, an evaluation system considering the ecological, economic, and social benefits was established, and the comprehensive benefits of watersaving irrigation in this area were evaluated with the optimization algorithm. The results showed that the comprehensive benefit of water-saving irrigation in the Yahekou irrigated area was evaluated as grade II “good” , selecting the Normal-Water-Level-Year as a typical year, following the life cycle of winter wheat-summer maize rotation mode as the time scale. The optimization algorithm not only ensures the accuracy of evaluation results but also takes into account the uncertainty of each index factor. It opens up a new way for the comprehensive benefit evaluation of water-saving irrigation in the research area and provides a new idea for the application and optimization of the cloud model algorithm, which has certain popularization value.
