| Abstract: |
| 【Objective】Considering the economy and practicability of the project as well as the reality of Jiangsu Province, the appropriate control scale of low-pressure pipeline irrigation project suitable for Jiangsu Province is proposed.【Method】The influencing factors of suitable control scale of pipeline irrigation system in rice-growing areas of Jiangsu Province are preliminarily analyzed, and the system optimization model of irrigation pipe network is established and solved by the boundary flow method. According to the optimization model, the annual cost of the pipe network system under different irrigation project scales is estimated, and the relationship between the system control scale and the annual cost per unit area is obtained.【Result】Drawing the relationship diagram between the system control scale and the annual cost per unit area, considering the investment in the project construction and the later operation, management and maintenance, it is suggested that the appropriate control scale for the pipe irrigation system project is 23—30 muhectares.【Conclusion】Proper selection of the control scale of the pipeline irrigation project according to the actual situation is of practical significance for saving project investment and management and maintenance in the later period of project operation. |
