一、前言西江是珠江的最大水系,大致自西向东流经云南、贵州、广西、广东向南入海。干流全长2,214公里,为华南水运一大动脉,又是四省(区)物资交流及出口贸易的通道。但上游河道狭窄,滩多、坡陡、水急,对航运不利。中下游自红水河以下,河道渐宽,可分段分级通航,由于各种原因尚未能充分发挥航运效益。为缓和流域内能源与交通的紧张状况,促进经济发展,研究以航运为重点,结合开发水电、防洪排涝及其他综合利用的方案,已是当务之急。二、航运规划多年来,经过有关部门勘察规划,逐
I. Introduction Xijiang River is the largest water system in the Pearl River and flows westward from east to west through Yunnan, Guizhou, Guangxi and Guangdong. The total length of 2,214 kilometers of the main stream is a major artery of water transport in southern China and a channel for the exchange of goods and export of four provinces (districts). However, the upper reaches of the river narrow, more beaches, steep slopes, floods, shipping adverse. Middle and lower reaches of the river from the Red River, the river gradually widening, classification can be graded navigation, due to various reasons not yet give full play to shipping efficiency. To alleviate the energy and traffic tension in the basin and promote economic development, it is imperative to study solutions that focus on shipping and combine hydropower, flood control and drainage and other comprehensive utilization. Second, shipping planning Over the years, after investigation and planning by the relevant departments, by
