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.
