引江补汉工程是南水北调后续工程首个开工项目，全长约194.7公里，多年平均调水量为39亿立方米。 工程建成后，可大幅提升中线一期工程供水能力和供水保证率，大幅提高汉江流域及区域水资源调配能 力，并为引汉济渭工程实现远期调水规模创造条件。 （文章来源：人民日报） 本报北京2月1日电记者从中国南水北调集团有限公司获悉：历经近4年艰苦奋战，1月30日，引江补汉工 程输水总干线出口段工程提前4个月贯通，成为全线首个贯通标段，标志着国家水网骨干工程建设取得 关键突破。 作为全线首个开工标段，引江补汉输水总干线出口段工程位于湖北省襄阳市谷城县、十堰市丹江口市境 内，全长5085米的隧洞需穿越牛河断层、两郧断裂带、刘家沟断层等复杂地质，围岩自稳能力差，突泥 涌水风险高，浅埋冲沟段和下穿水库施工难度极大，是全线安全风险最大、施工组织最难的标段之一。 中国南水北调集团江汉水网公司打造数字孪生智能建造中心，集成掌子面视频监控、人员车辆定位、水 情雨情监测等多种信息化模块，实现"一屏观全域，一网管全局"，推动规范化、标准化、精细化管理。 ...

Core Viewpoint - The Chinese government is accelerating the construction of major water conservancy projects to enhance water resource allocation and supply security, as outlined in the recent policy document on river protection and governance. Group 1: Major Water Projects - Since 2022, 12 major water diversion projects, including those in the Pearl River Delta and the Yangtze River, have been completed, adding an annual water diversion capacity of 124.8 billion cubic meters [1] - New projects, such as the North Bay Water Resource Allocation and the Jilin Water Network, are expected to add another 142.3 billion cubic meters of annual water diversion capacity upon completion [1] Group 2: Reservoir and Flood Control - 24 large reservoirs, including the Xijiang Datiangxia and Xinjiang Dashimen, have been completed, increasing water supply capacity by 34.6 billion cubic meters and flood control capacity by 26.6 billion cubic meters [3] - New flood control and key water source projects, including the Yellow River Guxian, are projected to add 49 billion cubic meters of water supply capacity and 36.7 billion cubic meters of flood control capacity [3] Group 3: Policy and Funding Support - The South-to-North Water Diversion Project has delivered over 800 billion cubic meters of water, benefiting 185 million people, and is crucial for optimizing water resource allocation and ensuring drinking water safety [5] - The National Development and Reform Commission (NDRC) is increasing support for major water projects, with an average increase of 20 percentage points in central investment support for new medium-sized irrigation and water diversion projects [7] Group 4: Integrated Infrastructure Development - The NDRC and the Ministry of Water Resources are focusing on the integration of flood control projects with irrigation and high-standard farmland construction to maximize comprehensive benefits [9]
