长江自古以来就是我国东西交通的大动脉,有“金色水道”之称.在其浩荡奔流的行程中,先后汇集了七百多条大支流,干支流航道总长七万多公里,占全国航道总长的五分之三以上。其中干流通航长度三千二百余公里。水运量约占全国内河水运总置的百分之八十左右.所以万里长江是我国内陆最大的水上运输交通线。 The Yangtze River has been the artery of the east-west traffic since ancient times, and is known as the “Golden Waterway.” In its mighty and prosperous journey, it has brought together more than 700 major tributaries, over a total length of more than 70,000 kilometers of dry and branch channels, Three-fifths or more. Among them, the length of navigable traffic is 3,200 kilometers in length. Water transportation accounts for about 80% of the total domestic waterway transportation, so the Yangtze River is China’s largest inland waterway transportation line.
