金沙江下游通航问题解决思路

Solution for navigation problem in downstream waterway of Jinsha River

从长江流域航道与航运的规划建设实践,论述流域航道建设的成就与经验。根据流域经济发展需求与水利水电建设现状,提出交通主管部门与水电开发建设部门合作共赢,研究解决金沙江下游700 km河段的航运问题。提出借鉴三峡枢纽工程的建设经验,在溪洛渡、白鹤滩和乌东德3座水利枢纽工程建设大型船闸或升船机,建设反调节梯级,适当提高水库防洪限制水位,解决水库变动回水区航道整治问题,实现金沙江下游全河段通航的建议。

The achievements and experience of the Yangtze River basin＇s waterway construction is expounded based on the practice of planning and construction. According to the demands of economic development and arrangement of hydro-power, this paper puts forward suggestions on achieving navigation of the downstream waterway of Jinsha River： taking the Three Gorges project＇s for reference to construct ship lock or ship lift in Xiluodu, Baihetan and Wudongde hydro-junctions, and construct reregulating reservoir and increase the flood control limited water level of the reservoir to deal with the channel regulation of the reservoir＇s fluctuating backwater area reservoir and realize navigation along the whole reach downstream Jinsha River.
