The Zhegan canal is a connecting project between the Yangtze River system and the Qiantang River system，which opens up an east passage to the sea for Jiangxi Province. Aiming at the route problems of Zhegan canal Yueling part，we carry out a comparison and selection of the canal route and local route of the watershed section. Analyzing the route layout，regional influence，water supply，connection section，building，project implementation，resettlement land occupation，etc.，and considering comprehensively route length，crossing elevation and shipping volume，we recommend the canal route，i.e. Longrao stream plan：by constructing the Damaiyu junction，Togngongshan junction，Jiudu junction，Hongqigang ship lock and Dongshanwu ship lock to control the lowest water level and excavate the canal. Three planes are compared and selected in the watershed section，and the reservoir plan with better route length and resettlement land occupation is recommended.
