珠江水系在云贵两地的众多水系中流域面积占比不大,但由于两地是珠江水系的发源地,所以份量格外厚重。珠江水系中下游地区水运飞速发展,离不开上游云贵两地的保优通畅。珠江水系在云贵两地的群山中崎岖前行,既应积极串联起沿岸区域的联动,也应让水运大通道的经济辐射作用完全发挥,实现云贵两地边远山区精确扶贫的国家战略。贵州、云南两省的水运体系中,主要包括了长江和珠江,其中长江水系在两省的水运体系中占比很高,而珠江水系的 Pearl River water system in Yunnan and Guizhou, many of the water system in the basin area accounted for a small proportion, but because the two places is the birthplace of the Pearl River system, so particularly heavy weight. The rapid development of water transport in the middle and lower reaches of the Pearl River water system can not be achieved without the smooth flow of the upper reaches of Yunnan and Guizhou. The pearl river system is going through a rugged mountain range between the Yunnan and Guizhou regions. It should not only actively coordinate the linkage along the coast but also give full play to the economic radiation of the major aqueduct and realize the national strategy of accurately alleviating poverty in the remote mountainous areas of Yunnan and Guizhou. Among the water transport systems in Guizhou and Yunnan provinces, the Yangtze River and the Pearl River mainly include the Yangtze River water system, which accounts for a large proportion of the water transport systems in the two provinces. However,
