这场以大河为名的聚会虽已落幕，却将一条河流与一个文明的对话刻进时光。我们不仅聆听了浩荡的历 史回响，也触摸到了那些被黄河泥沙默默守护千年的文明秘语——它们分别藏在了陶纹经纬间、堤坝肌 理中、基因序列里，无声地回答着"何以中国"的永恒之问。 □朱波 近日，"何以中国·黄河安澜"网络主题宣传活动在河南落下帷幕。自启动以来，活动以大河为名，赴安 澜之约，围绕"中华源""民族魂""万象新"三大篇章，系统梳理黄河文化的根脉传承、治水智慧与时代新 貌，深刻回应了"何以中国"这一宏大命题，获得广泛的社会关注与积极反响。 就连泥沙，也是历史的书写者。地质岩芯中的花粉与炭粒，默默记录气候变迁如何影响农耕与游牧文明 的互动节奏。它无时无刻不在提醒着我们，北宋纵然技术先进，仍难逃黄河改道之困；真正的智慧从来 不是征服自然，而是读懂河流律动，与之共生。 黄河的伟大，因其混沌吞吐万千气象，因其包容文明在激荡中生生不息。陶片、堤坝、草秸、基因、花 粉……这些微不足道的事物，用数千年的沉默诉说文明的真谛——在差异中融合，在顺应中创新，在时 间里沉淀。 "何以中国·黄河安澜"采风活动暂告一段落，但对黄河的解读永无终章。我们应该记住的，不仅是 ...

Core Viewpoint - The article highlights the historical and cultural significance of the Daicun Dam, which has been a crucial infrastructure for water management and navigation in the Grand Canal system for over 600 years, and its recent recognition as a heritage site by the Ministry of Water Resources in China [4][5][9]. Group 1: Historical Significance - The Daicun Dam, located on the Dawan River in Shandong Province, has played a vital role in directing water flow to the Grand Canal, facilitating transportation and flood control throughout its history [4][6]. - The dam was constructed to address the challenges posed by the high terrain of the Grand Canal in the Jining Nanwang section, which hindered the passage of large vessels [5][6]. Group 2: Engineering and Design - The dam's design includes a main stone dam, a Dougong embankment, and a spillway, which work together to manage water flow effectively [7][8]. - The foundation of the dam is reinforced with closely packed cypress piles, which are treated to enhance durability and reduce water absorption, ensuring stability against flooding [7][8]. Group 3: Modern Developments - Since 2022, the Daicun Dam has transitioned from its original function of water diversion to becoming a recreational area, attracting visitors for leisure activities and cultural tourism [9][10]. - The local government is promoting the integration of water management with cultural tourism, enhancing the ecological environment and preserving the heritage of the Grand Canal [9][11].
