The resistance loss of sprinkler irrigation system is an important parameter, it has significance and practical value for studying its device characteristics. In this study, according to the selected materials and setting modes, both the pressure drop along the pipe and the local resistance loss were calculated out. The theoretical device characteristics of one sprinkler irrigation system was analyzed. A calculating schema has been carried out in order to apply the method to any sprinkling system. Experimental study was carried out for this system. Water distribution maps for the sprinklers were drawn using Matrix Laboratory (MATLAB). The hydraulic characteristics were as follow, 7.2, 3.0, 10.0 mm/h was the average, minimum, and maximum irrigated intensity, respectively. It supplied theoretical foundation for the reasonable application of sprinkler irrigation system for the future.
