摘要
变化环境下极端气象水文事件频发,长江、黄河面临同枯风险.在国家水网建设背景下,为提高长江、黄河同枯的极端不利情景下黄河流域水资源安全保障能力,本文分析了长江、黄河两大流域水资源安全面临的现实问题,识别了变化环境下大型流域枯水遭遇—水危机形成—跨流域调水潜力—多线路成网互济—极端枯水下水资源安全保障中亟需破解的关键科学问题,构建了水网布局下黄河流域应对极端枯水的总体研究框架,提出该领域重点研究方向包括:变化环境下长江、黄河极端枯水遭遇规律与空间变异机制,水危机风险多链路传导与复合影响定量评估,极端枯水下跨流域调水挖潜增供,长江和黄河跨流域联合调配与多线路互济精细化调控、极端枯水下流域水资源韧性提升优化调控等.
Abstract
Extreme meteorological and hydrological events frequently occur in the changing environment.The Yangtze River and Yellow River are facing the risk of simultaneous dry events.This paper analyzes the practical problems encountered in the Yangtze River basin and Yellow River basin following the construction of the national water network in order to ensure water resources security in the Yellow River basin when these two rivers experience simultaneous dry events.Urgent key scientific problems that need to be addressed include simultaneous dry events of large-scale basins in the changing environment,water crisis formation,interbasin water transfer potential,water network formation and the water transfer mechanism of multi-line projects,water resources security assurance during extreme dry events.An overall research framework for addressing extreme dry events in the Yellow River basin under the layout of the water network is proposed.Key research directions are analyzed from five aspects,namely,occurrence patterns and spatial variation mechanisms of simultaneous dry events in the Yangtze River and the Yellow River;quantitative assessment of multi-link transmission and compound impact of water crisis risk;interbasin water transfer potential in extreme dry events,interbasin water allocation and refined regulation of multi-line water transfer projects;and improvement of the resilience of thebasin water resource system during extreme dry events.
