| Abstract: | Based on the research on the later-evaluation method of water-saving improvement project in irrigation areas,entropy method was applied to determine the index weight of the later-evaluation of water-saving irrigation improvement project.Nine irrigation areas in Guanzhong of Shaanxi were analyzed.The studies showed that entropy method could effectively reduce the impact of subjective factors on the evaluation results and improve the authenticity of the project evaluation. |
