Abstract: At present，technology of building information modeling（BIM）has developed rapidly.In view of problems of complex design content and low construction efficiency of farmland and water conservancy projects，using BIM technology for three-dimensional modeling can realize visualization and co-assimilation of design.BIM software is used to quickly realize visualization of single project.The intuitive and three-dimensional design model not only enhances participants′ understanding of the project，but also greatly improves design and construction quality and speed，and improves overall project construction quality.Focusing on design of farmland water conservancy projects in construction of high-standard farmland，based on analysis of characteristics of farmland water conservancy projects，use of BIM technology was further studied to realize visualization and integration of high-standard farmland projects.
