环境变化下我国西南河流源区的水文情势发生显著变化,对水资源利用和水电开发有深刻 影响,其径流变化规律及对环境质量的影响与适应性对策是国际研究的前沿和热点。“西南河 流源区径流变化和适应性利用”重大研究计划以雅鲁藏布江、澜沧江、怒江、长江源区、黄河 源区等西南河流源区为对象,研究径流演变规律、生源物质迁移转化规律、供水-发电-环境等 多目标互馈关系,提出变化环境下径流适应性利用的理论和方法,为我国水安全和能源安全提 供基础理论和科学支撑。本申请项目用于该重大计划的战略研究、指导专家组调研与组织学术 交流活动,通过战略研究、专家研讨、国际交流等,更好的对重大计划涉及到的关键问题、前 沿动态、集成升华思路做前瞻性的指导和统筹。

The hydrologic regime of the headwater in southwest China has changed obviously under the changing environment, which has a profound impact on the utilization of water resources and hydropower development. The characteristics of runoff variation, its impact on the environment quality, and the adaptive management become the research frontier among the international communities, which are also the principal research themes of major research plan “Runoff Change and its Adaptive Management in the Major Rivers in Southwestern China” launched by NSFC in 2015. The typical study rivers of the plan are Yarlung Zangbo River, Lantsang River, Nujiang River, the source regions of the Yangtze River and Yellow River. The research purposes are to study the runoff variation, biogeochemical processes, and the water-energy-environment nexus. New theories and methods for adaptive management of water resources under changing environment will be developed, which can provide scientific support for the water and energy security of China. This application project will conduct strategic research of the major research plan. It will also provide support for direct investigation of expert board and organizing academic meetings. With these the expert board can offer better guidance for the strategic question and synthesis of the plan.
