Abstract
This paper focused on the development of a framework for collective water resources management in China to meet the change of drought and flood. Based on the observational data of drought and flood from 1950 to 2009 and the precipitation from 1961 to 2010, using the Standardized Precipitation Index (SPI) method, the evolutionary characteristic of drought and flood was analyzed. The results showed that drought and flood occurred frequently, simultaneous occurrences of drought and flood and the rapid shift between the two were increasing. The framework for collective strategies responding to drought and flood under this ever-changing environment was presented. A series of potential mitigation, prevention, and adaptation strategies were discussed. These included both planning and implementation side strategies. In regard to planning, the strategies for dealing with drought and flood should be shifted from crisis management to collective management, unifying normal and emergency management. Combination risk zoning of drought and flood should be conducted and collective emergency planning should be formulated. Moreover, the regulation capability of water conservancy projects group should be optimized to the highest possible level. In regard to implementation, based on the water resources collective management, rational water allocation for both normal and extreme value processes should be implemented. The water conservancy project groups for the extreme value process should work together, and the flood limit water level of reservoirs should be controlled dynamically.
