The Li River or Li Jiang is the name for the upper reaches of the Gui River in northeastern Guangxi, China. It is part of the Xijiang River system in the Pearl River basin, flowing 164km (102miles) from Xing'an County to Pingle County.
The Li River originates in the Mao'er Mountains in Xing'an County and flows in the general southern direction through Guilin, Yangshuo and Pingle. In Pingle, the Li merges with the Lipu and Gongcheng, becoming the Gui, and in turn falls into the Xijiang, the western tributary of the Pearl River. The upper course of the Li River is connected by an ancient Lingqu canal with the Xiang River, which flows north into the Yangtze; this in the past made the Li and Gui Rivers part of a highly important waterway connecting the Yangtze valley with the Pearl delta.
The 439km (273miles) course of the Li and Gui Rivers is flanked by green hills. Cormorant fishing is often associated with the Lijiang.
Cruises on the Li are famous, attracting millions of visitors per year.[1]
The Li and its tributaries drain the area from Guilin to Yangshuo, descending from 141m (463feet) at Guilin to 103m (338feet) at Yangshuo. Mean flow past Guilin is 215 cubic meters per second, and alluvium sediments consisting of well-sorted gravels covered by silty sand, forming floodplains and terraces along its route. Yet, it is the 2600m (8,500feet) of Devonian and Carboniferous limestones and karst terrain within the Guilin basin, that gives the area a dramatic landscape. Two distinctive types of karst are found, Fengcong, and Fenglin, which have evolved for the past 10-20 million years, within the Cenozoic.[1]
Fengcong karst dominates the course of the Li River and is defined as a group of limestone hills with a common limestone base, with deep depressions (or dolines) between the peaks, and sometimes described as peak cluster depression karst. Hundreds of caves are present in this terrain, with 23 having passages longer than -1 km alongside the Li River gorge. The longest is the Guanyan Cave System which extends from Caoping to Nanxu.[1]
Fenglin dominates the area around Yangshuo and south of Guilin and is defined as isolated limestone hills separated by a flat limestone surface generally covered by loose sediments, and sometimes described as a peak forest plain. The best-known fenglin is the tower karst around Yangshuo. These towers consist of strong and massive limestone forming near vertical sides with base diameters less than 1.5 times their height. The heights of the towers range from 30 to 80 m in the central basin but can be as high as 300 m near the Fengcong. Fenglin evolves from Fengcong by slow and continuous tectonic uplift, associated with the Himalayan orogenic zone, and even slower erosion of the towers.[1]
Famous show caves in the Guilin area include the Qixing Dong and the Luti Dong.[1]
