The Major Rivers in Southwestern China (MRSC) is the strategic reserves of water resources, which is a sensitive region for climatic changes. In recent years, the steamflows in MRSC takes on complex changing characteristics and the future trend is not disclosed. The major research plan “Runoff Change and its Adaptive Management in the Major Rivers in Southwestern China” focuses on the pivotal scientific issue and the international frontier of runoff variation and adaptive utilization and meeting the national major strategic needs for water and energy security. Based on the study area of MRSC, the cutting edge research will be performed via a steady and massive financial support. This project is strategic research for the major research plan. It will carry out a serial of activities, e.g., ascertainment, investigation and discussion for experts, academic communication in domestic and abroad, and propaganda campaign. The project intends to perform a strategic problem study, formulate a special topic document, develop an integrated scheme of the major research plan, understand academic frontier, and perform a leading and planning advice for the progress.
