Abstract: Nanpan River and Beipan River are two important water systems in the upper reaches of the Pearl River, both originating from Maxiong Mountain in Wumeng Mountain range, Zhanyi District, Qujing, Yunnan Province. Nanpan River and Beipan River tightly encircles Southwest Guizhou Autonomous Prefecture and merges into the Hongshui River in Shuangjiang town of Ceheng County, forming a rare U-shaped “water bag” of the Panjiang River. Expanding the navigation capacity of the Beipan River-Hongshui River channel is conducive to improving the investment environment along the Yangtze River and ensuring that the three provinces and autonomous regions of Yunnan, Guizhou and Guangxi build a moderately prosperous society with the whole nation simultaneously. Expanding the navigation capacity of the Beipan River-Hongshui River channel is conducive to further improving the comprehensive transportation system along the Yangtze River, better meeting the new requirements for the transportation infrastructure capacity of the three provinces and autonomous regions of Yunnan, Guizhou and Guangxi in achieving economic and social development goals, and improving the contribution rate of the Beipan River-Hongshui River water transport to economic and social development. Expanding the navigation capacity of the Beipan River-Hongshui River channel is conducive to promoting the scale, intensive development of the Beipan River-Hongshui River port and the standardization and large-scale development of transport ships, enhancing the service capacity and development level of the Beipan River-Hongshui River water transport, and giving full play to the support and safeguard role of Beipan River-Hongshui River water transportation in the continuous development of the three provinces and autonomous regions of Yunnan, Guizhou and Guangxi, in strengthening the economic relations with other provinces and districts in the Pearl River Basin.

Key words: Country with strong transportation network, Beipan River, Hongshui River, Water transportation, Transportation service
