“定海神针”守护黄河安澜
Zhong Guo Xin Wen Wang· 2025-09-23 06:59
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。 小浪底管理中心开发公司综合部副部长李立刚接受记者采访时表示,自2002年起,小浪底水利枢纽 已累计完成30次调水调沙作业,显著提升了下游河床的过流能力,由不足1800立方米每秒增加至5000立 方米每秒。黄河下游河道主河槽平均下切3.1米,有效保障了黄河下游的行洪安全,实现了环境协调与 水利工程的良性互动。 近年来,小浪底水利枢纽加快数字化转型,于2023年在水利系统率先建成了数字孪生小浪底平台, 成立小浪底 ...

应对黄河上中游洪水 小浪底水利枢纽今年首次开启汛期泄洪运用

Group 1 - The Xiaolangdi Water Control Project has initiated flood discharge operations for the first time this flood season, releasing water at a flow rate of 800 cubic meters per second to manage high-density sediment-laden floodwaters caused by heavy rainfall in the Yellow River's upper and middle reaches [1] - As of July 29, the water level at Xiaolangdi Reservoir reached 226 meters, with a corresponding flood control capacity of 8.7 billion cubic meters, providing strong support for subsequent flood control and sediment reduction efforts [1] - The management center is utilizing a digital twin system for real-time monitoring and predictive analysis of water and sediment conditions, ensuring effective operational strategies for the reservoir [2] Group 2 - The ongoing high sediment flood in the Yellow River's upper and middle reaches is being closely monitored, with the management center employing advanced technologies such as radar, drones, and automated monitoring platforms to enhance inspection and monitoring efforts [2] - The focus is on increasing the frequency of sediment monitoring at critical points within the reservoir area to ensure the safe and stable operation of the Xiaolangdi Water Control Project [2]

Core Viewpoint - The article discusses the proactive measures taken by the Yellow River Water Resources Department to manage water and sediment during the flood season, emphasizing the importance of coordinated water and sediment regulation to mitigate flooding risks and manage sediment effectively in the Yellow River basin [1][2][4]. Group 1: Flood Management Strategies - The Yellow River basin is expected to officially enter the flood season on July 1, with a focus on coordinated water and sediment management through key reservoirs like Xiaolangdi, Wanjiazai, and Sanmenxia [1][2]. - The strategy includes using large flows to flush sediment from the riverbed and reservoirs, which helps reduce sediment accumulation and prolongs the lifespan of the reservoirs [1][3]. - Since 2002, there have been 29 instances of coordinated water and sediment management in the Yellow River basin, which has helped prevent the riverbed from rising and has initially curbed the shrinking of the main channel [2][4]. Group 2: Technological Integration - The Xiaolangdi reservoir has seen a significant increase in efficiency, with decision-making processing times reduced from 30 minutes to 5 minutes, resulting in an 84% improvement in operational efficiency [3]. - The use of drones for monitoring potential hazards near the Xiaolangdi reservoir enhances safety and ensures smooth water and sediment management operations [2]. Group 3: Weather and Environmental Challenges - The Yellow River basin has experienced a 20% decrease in precipitation compared to the average this year, with forecasts indicating a potential 10% increase in rainfall during the flood season, particularly in the lower reaches [4][5]. - The flood season poses complex challenges, including the risk of sudden droughts and floods, as well as the likelihood of extreme rainfall in localized areas [4][5].
