Abstract: With N city B water-saving park land consolidation as an example, this paper introduces the water-saving park in land consolidation planning and design method of irrigation and water conservancy and related hydraulic calculation, mainly including： the selected water irrigation and irrigation pipe irrigation methods, channel drainage; Determine the micro-sprinkler irrigation system, carry out the preliminary design and related hydraulic calculation of high efficiency and water saving irrigation project. In this way, land use efficiency and land consolidation quality can be improved through the construction of irrigation and water conservancy projects.

Key words: land consolidation, micro sprinkler irrigation, water-saving park
