(何以中国·黄河安澜)"定海神针"守护黄河安澜 中新网洛阳9月23日电(记者 谢艺观)在河南省洛阳市以北40千米，黄河中游最后一段峡谷的出口处，有 一枚"定海神针"守护黄河安澜。 这就是小浪底水利枢纽。作为黄河治理开发保护的关键控制性工程，它控制着黄河92.3%的流域面积、 91.2%的径流量和近100%的输沙量，在黄河治理中占据着举足轻重的地位。 黄河是中华民族的母亲河，也是一条桀骜难驯的忧患之河，径流泥沙含量世界居首，年均输沙量高达16 亿吨。大量泥沙淤积在下游河床上，形成地上悬河。小浪底水利枢纽的调水调沙功能，犹如一把利剑， 直击黄河泥沙淤积的要害。 近日，在"何以中国·黄河安澜"网络主题宣传活动中，记者来到小浪底水利枢纽看到，正赶上汛期调水 调沙作业，巨大的水流如"黄龙"喷涌而出。 编辑：万可义 来源：中国新闻网 广告等商务合作，请点击这里 本文为转载内容，授权事宜请联系原著作权人 中新经纬版权所有，未经书面授权，任何单位及个人不得转载、摘编或以其它方式使用。 关注中新经纬微信公众号(微信搜索"中新经纬"或"jwview")，看更多精彩财经资讯。 小浪底水利枢纽。谢艺观 摄 小浪底管理中心开发公司综合 ...

Core Viewpoint - The ecological protection and high-quality development of the Yellow River basin has become a significant national strategy, with ongoing efforts to enhance water quality and promote sustainable development in the region [2][3]. Group 1: Ecological Protection and Development - The Yellow River's water quality has shown steady improvement, with Shandong Province compensating Henan Province with 62.07 million yuan for ecological protection in 2024 [3]. - Since 2019, Henan has addressed 14,000 "four chaos" issues related to the Yellow River, with 6.45 million acres of afforestation and 27,800 acres of wetland restoration completed [5]. - The water quality of the Yellow River in Henan has consistently reached Class II since 2020, with significant improvements in soil quality [6]. Group 2: Water Management and Safety - The water flow from the Xiaolangdi Reservoir was reduced to 600 cubic meters per second, marking the end of the Yellow River's water and sediment regulation for 2025 [7]. - Since the first water and sediment regulation in 2002, the main channel of the Yellow River has deepened by an average of 3.1 meters, with the minimum flow capacity increasing from 1,800 cubic meters per second to approximately 5,000 cubic meters per second [8]. - The flood control system in Henan has been enhanced, with major water conservancy projects and a comprehensive flood control engineering system in place [9]. Group 3: Cultural Heritage and Tourism - The newly opened Han-Wei Luoyang Ancient City Ruins Museum showcases over 1,300 cultural relics representing Yellow River culture, highlighting the region's commitment to cultural preservation [10]. - The Yellow River cultural tourism belt has seen significant visitor numbers, with 6.45 million tourists and 37.11 billion yuan in tourism revenue during the "May Day" holiday, reflecting a year-on-year growth of 4.6% and 4.8% respectively [10]. Group 4: Green Transformation and Economic Development - Henan Province has initiated a "waste-free city" construction program across the Yellow River basin, with several cities included in the national list for the 14th Five-Year Plan [11]. - The province has implemented ultra-low emissions modifications in key industries and achieved high proportions of new energy vehicles in public transport [11]. - By 2024, energy consumption per ten thousand yuan of industrial added value and water usage per ten thousand yuan of GDP in Henan are expected to decrease by 23.5% and 23.1% compared to 2019 [12].

Core Viewpoint - The article discusses the implementation and impact of the "water-sand regulation" theory on the Yellow River, highlighting its significance in managing sediment and improving flood control capabilities. Group 1: Water-Sand Regulation Implementation - On June 28, the Xiaolangdi Water Control Project increased its water and sediment discharge to 4,600 cubic meters per second, marking the seventh day of its operation [2] - As of June 29, the total water discharged from Xiaolangdi exceeded 1.8 billion cubic meters [2] - The project utilizes a digital twin platform for dynamic analysis and scientific scheduling to ensure effective water-sand regulation [2] Group 2: Historical Context and Technological Innovations - Since 2002, the Yellow River Water Resources Commission has pioneered the "water-sand regulation" theory, conducting multiple tests and operational runs to manage sediment effectively [3] - The cumulative sediment cleaning in the downstream riverbed has exceeded 2.1 billion cubic meters, significantly improving flood capacity from below 2,000 cubic meters per second to over 5,000 cubic meters per second [3] - The establishment of the world's first mathematical model for water-sand regulation has enabled precise calculations for sediment transport [3] Group 3: Environmental and Ecological Benefits - The regulation efforts have provided 1.46 billion cubic meters of ecological water to the river delta, supporting wetland restoration and biodiversity [4] - The integration of traditional wisdom with modern technology in water-sand regulation has been recognized with a national science and technology progress award, showcasing its potential as a model for global river management [4]
