时代在发展，"模型黄河" 的进化也从未止步。夏修杰称，随着治黄需求日益精细化，原有模型在信息 化、智能化监测等方面需要有所提升。 试验基地内挂着升级改造标语。 谢艺观 摄 (何以中国·黄河安澜)800米 "模型黄河" 成破解治黄难题科技密码 中新网郑州9月23日电(记者 谢艺观)把黄河装进实验室，是什么体验？在郑州 "模型黄河" 试验基地，黄 河下游小浪底至陶城铺河段被"浓缩"成800米长的物理模型，成为破解黄河治理难题的"科技密码"。 黄河水利科学研究院泥沙研究所正高级工程师夏修杰告诉记者，"黄河下游动床模型"按1:600水平比 尺、1:60垂直比尺构建，精准复现黄河下游299公里长的游荡性河段和165公里长的过渡性河段。而这一 区域正是黄河下游河道游荡摆动最大、冲淤演变最复杂、悬河形势最严峻、滩区人口最密集的河段，也 是防洪威胁最大、最难治理的河段。 图为黄河下游动床模型。 谢艺观 摄 "黄河宁，天下平"。为实现黄河的长治久安，水利部黄河水利委员会在2001年提出了"三条黄河"， 即"原型黄河""数字黄河""模型黄河"的治黄新理念。 如果说"数字黄河"是把黄河"装进"计算机，那么"模型黄河"就是把黄河"放 ...

Core Insights - The meeting led by Li Guoying emphasizes the ongoing flood risk as the primary threat to the Yellow River basin, highlighting the need for improved water-sand regulation and flood disaster reduction systems [2][2] Group 1: Flood Risk and Water Management - Flood risk remains the biggest threat in the Yellow River basin, with the imbalance of water-sand relationships identified as a key issue [2] - There is a call to accelerate the improvement of water-sand regulation and flood disaster reduction systems, including the establishment of a comprehensive flood control engineering system and monitoring systems for rainfall and flood disasters [2] Group 2: Water Resource Management - Water resource scarcity is the most prominent contradiction in the Yellow River basin, necessitating strict adherence to the "Four Waters and Four Determinations" principle [2] - A total water usage control system covering the entire basin is to be established to enhance the efficient and economical use of water resources [2] Group 3: Ecological Protection - The ecological fragility of the Yellow River basin requires strengthened water ecological protection and management, including unified water quantity scheduling and ecological flow management [2] - There is a focus on comprehensive governance in areas with high concentrations of coarse sediment, particularly in the Loess Plateau [2] Group 4: Water Rights and Legal Framework - The meeting advocates for deepening water conservancy reforms and exploring the regulation of water rights trading [2] - The implementation of the Yellow River Protection Law and enhanced cross-regional and cross-departmental law enforcement collaboration is emphasized [2]
