Core Viewpoint - The Yangtze River Economic Belt has achieved significant ecological and economic advancements over the past decade, emphasizing ecological priority and green development, leading to a harmonious coexistence of nature and human activities [1]. Environmental Protection and Quality Improvement - The proportion of water quality classified as good has increased from 67% to 96.5% [4]. - Total phosphorus concentration in the Yangtze River basin has decreased by over 40% compared to ten years ago [4]. - More than 1,300 national nature reserves have completed key ecological environment issue rectifications [4]. - Over 1,280 key rivers have achieved full coverage of environmental emergency management [4]. Infrastructure and Economic Development - The high-grade navigable waterway mileage has reached 11,500 kilometers [6]. - By 2025, the throughput of Yangtze River mainline ports is expected to reach 4.2 billion tons, with the number of major ports increasing to 18 [6]. Flood Control and Water Resource Management - Successfully managed the 2020 regional flood by preventing 49 billion cubic meters of floodwater, protecting 1,752 million people and 1.1 million hectares of farmland [8]. - Ensured safe drinking water for urban populations and irrigation for 1.83 million acres of autumn crops [8]. Green and Low-Carbon Industrial Transformation - Three technology innovation centers and eight national laboratories have been established along the river [11]. - By 2025, the production of new energy vehicles in Shanghai, Jiangsu, Zhejiang, Anhui, and Chongqing is expected to exceed one million units each [11]. - 24 cities and parks have been designated as national carbon peak pilot areas, with 14 zero-carbon parks established [11]. Pollution Control and Regulatory Framework - Over 160,000 kilometers of river and lake shorelines have been inspected, with more than 200,000 pollution outlets accurately identified [12]. - A comprehensive supervision management system for pollution outlets has been established [12].

Multi-Modal Transport and Connectivity - The implementation of a comprehensive transport system has led to significant improvements in multi-modal transport [14]. - By the "14th Five-Year Plan" period, the railway port rate for major ports along the Yangtze River is expected to exceed 90%, with an annual growth rate of over 30% for container rail-water intermodal transport [14]. Flood Prevention Infrastructure - More than 300 large reservoirs have been built in the Yangtze River basin, with a flood control capacity of 80 billion cubic meters [15]. - Over 1,000 kilometers of riverbanks have been treated to stabilize the river flow in the middle and lower reaches [15].
