Watershed water resources management is important and yet complicated, so it is urgent to find a scientific management pattern and system. On the basis of summarizing the domestic and foreign experiences of watershed water resources management, we discussed the necessity of synergetic management of watershed water resources, put forward the synergetic management pattern, described its main characteristics and constructed the management system based on the following three aspects: organizational system, content system and institutional system. Finally, taking the Qinhe River Basin as an example, aiming at the problems in the utilization and management of local water resources, we constructed a synergetic management system of water resources for this basin. This research aims to propose a new synergetic management pattern and system for watershed water resources management, and provide some reference for the practical water resources management of the Qinhe River Basin.
