摘要
针对江汉平原中部尚无纵贯的高等级航道及长江中游荆江航道迂曲且存在碍航因素、进而制约内河运量增长的问题,为构建和完善地区高等级内河航道网络,规划建设与荆江航道并行的横向高等级航道即荆东运河,作为荆州—武汉的第 2 航道,并在汉江下游沙洋段与长江中游岳阳段间规划建设将汉江与长江及湘江航道连通的纵向高等级航道即汉湘运河,两运河与现有的荆江、汉江及江汉运河共同形成江汉平原"一纵三横"的航道格局.采用定性定量结合、比选分析等方法,考虑运河建设条件、功能定位、河道条件、水资源、地貌地质等,提出 9 梯级线路方案,进而构建沿线运河经济带,实现水路及土地资源的综合开发效益.
Abstract
In view of the problems that there is no longitudinal high-grade waterway in the middle of Jianghan Plain and that the Jingjiang waterway in the middle reaches of the Yangtze River is winding and has obstructing factors,thus restricting the growth of inland waterway traffic,and in order to construct and improve the regional high-grade inland waterway network,a horizontal high-grade waterway parallel to the Jingjiang waterway,namely Jingdong Canal,is planned to construct as the second waterway between Jingzhou and Wuhan.In addition,Hanxiang Canal,a longitudinal and high-grade channel connecting Han River with the Yangtze River and Xiangjiang River,is planned to be built between Shayang section of the lower Han River and Yueyang section of the middle Yangtze River.The two canals,together with the existing Jingjiang River,Han River and Jianghan Canal,form a channel pattern of"one vertical and three horizontal"in the Jianghan Plain.This paper adopts qualitative and quantitative combination,comparative analysis and other methods,considering canal construction conditions,functional positioning,river conditions,water resources,geomorphology and geology,etc.,and proposes a route scheme with 9 steps,so as to build a canal economic belt along the route and realize the comprehensive development benefits of waterway and land resources.
