长江货运量有多大？比全球其它国家内河货运量加起来还多

Core Insights - The cargo throughput of the Yangtze River mainline ports has increased by 71% over the past decade, reaching 4.2 billion tons, maintaining its position as the world's leading inland river in terms of cargo volume [1][27] Group 1: Cargo Volume and Comparisons - The 4.2 billion tons of cargo is equivalent to needing 105 million heavy trucks, which could circle the equator 1.3 times if lined up [4] - In comparison to other major rivers, the Amazon River's annual cargo volume is approximately 1 million tons, which is only 1/42 of the Yangtze's volume [4][13] - The Mississippi River in North America has an annual cargo volume of about 600 million tons, ranking fourth globally, but still less than 1/7 of the Yangtze's volume [6] Group 2: Infrastructure and Development - Over the past decade, the high-grade waterways of the Yangtze River have expanded from 8,000 kilometers to 11,000 kilometers, effectively creating a "water highway" [15] - The number of major ports along the Yangtze has increased from 10 to 18, with 127 new production berths added, enhancing the capacity for large cargo ships [17] - The integration of ecological improvements has led to a 90% reduction in vessel detention rates due to sedimentation, demonstrating that environmental protection can coexist with increased cargo capacity [19][21] Group 3: Economic Impact - The Yangtze River's cargo volume supports 80% of the iron ore and thermal coal transportation for industries along the river, indicating its critical role in the supply chain for steel and electricity [15][22] - The cost advantage of inland waterway transport is significant, with costs being only half of rail and one-fifth of road transport, contributing to the competitiveness of manufacturing clusters in the Yangtze River Delta and Chengdu-Chongqing regions [22] - In the first 11 months of 2025, the foreign trade import and export value of the 11 provinces and cities along the Yangtze Economic Belt reached 19.12 trillion yuan, accounting for 46.4% of the national total, highlighting the economic significance of the 4.2 billion tons of cargo [22] Group 4: Future Prospects - The 4.2 billion tons of cargo not only represents a numerical achievement but also symbolizes the Yangtze Economic Belt's connectivity between western mineral resources and eastern manufacturing bases, as well as its integration into global trade networks [24] - The Yangtze River is poised to continue playing a vital role in supporting high-quality economic development, with an average of one cargo ship passing every three minutes in the lower reaches [25]
