The Gui River (Chinese: 桂江; pinyin: Guì Jiāng) is a major river located in the Guangxi Zhuang Autonomous Region of southern China. It is a significant tributary of the Xi River, which itself is part of the larger Pearl River basin.
Geography and Course
The Gui River is formed by the confluence of the Li River (Lijiang) and the Lipu River at Pingle County. From this junction, the river flows in a generally southerly direction through the eastern part of Guangxi. It eventually joins the Xi River at Wuzhou, near the border with Guangdong province. The total length of the river system, including its upper reaches (the Li River), is approximately 426 kilometers (265 miles).
Hydrology and Environment
The river basin experiences a humid subtropical climate characterized by significant monsoonal rainfall, which leads to high seasonal variations in water levels. The river traverses diverse terrains, including the famous karst landscapes in its upper reaches (near Guilin) and more mountainous or hilly regions as it moves south toward Wuzhou.
Historical and Economic Significance
Historically, the Gui River has been a vital artery for transportation and communication in southern China. It gained immense strategic importance during the Qin Dynasty with the construction of the Lingqu Canal. This canal linked the headwaters of the Li River (the Gui's upper reach) with the Xiang River (a tributary of the Yangtze River), effectively creating the first inland waterway connection between the Yangtze River basin and the Pearl River Delta.
In modern times, the river continues to serve as a source for irrigation, hydroelectric power, and local transport. The upper section of its system, the Li River, is one of China's most prominent tourist destinations, noted for its limestone karst scenery. The lower Gui River serves as an important industrial and commercial corridor for the city of Wuzhou.
