The scientific significance of Guilin's landscape is from the concentration of the Guilin-Yangshuo type of peak forest karst landforms. These formations are internationally recognized by the karst community as the world's typical representative of peak forest karst landforms and a model of tropical and subtropical peak forest landforms.

In 1921, Guilin became one of the headquarters of the Northern Expeditionary Army led by Sun Yat-sen. [8] In 1940, Guilin City was established. [9] [10] Guilin was the provincial capital of Guangxi before 1912 and from 1936 to 1949. Guilin became one of the most important military, transport, and cultural centers of China during World War II.
The region is recognized as the world’s type area for karst landform development in the humid tropics and subtropics. The World Heritage Property of South China Karst is a serial property that includes seven karst clusters in four Provinces: Shilin Karst, Libo Karst, Wulong Karst, Guilin Karst, Shibing Karst, Jinfoshan Karst, and Huanjiang Karst.
Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum. [1] It has also been documented for weathering -resistant rocks, such as quartzite , given the right conditions. [ 2 ]
China's karst regions are almost all formed in rocks of Devonian to Triassic age. [11] [12] Near Guilin the lowering of the base level, through uplift and river erosion, has formed prominent karst hills. It is estimated that the river erodes down 50–100 mm/kyr, from this the age of the karst landscape is estimated at 10–20 million years .
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 ...
Global distribution of major outcrops of carbonate rocks (mainly limestone, except evaporites). The English word karst was borrowed from German Karst in the late 19th century, [6] which entered German usage much earlier, [7] to describe a number of geological, geomorphological, and hydrological features found within the range of the Dinaric Alps, stretching from the northeastern corner of ...
