Dongge Cave is a large karst cave system in the Lingui District near Guilin in Guangxi Zhuang Autonomous Region, China. The cave is noted for its extensive speleothem formations, well-preserved stalagmites used in high-resolution paleoclimate studies, and development as a show cave that attracts domestic and international visitors. Scientific research conducted there has linked cave deposits to wider records from East Asia and contributed to reconstructions of late Quaternary monsoon variability.
Dongge Cave sits in a karst landscape of southern China, approximately 20–30 kilometres southwest of central Guilin and within the administrative boundaries of Lingui District. The site is part of the broader South China Karst region, which includes famous features near Yangshuo County and other scenic karst towers. The cave occupies carbonate bedrock formed during the Paleozoic and Mesozoic eras and is influenced by the subtropical monsoon climate that affects Guangxi Zhuang Autonomous Region, Yunnan to the west, and the South China Sea to the southeast.
The cave developed in thick sequences of carbonate rocks through dissolution by slightly acidic groundwater, a process driven by carbon dioxide exchange with soil and vegetation typical of subtropical terrains. Speleothems within the cave include stalagmites, stalactites, flowstones, and helictites; many stalagmites show banding used for geochronology. The mineralogy is dominated by calcite precipitates influenced by dripwater chemistry and temperature linked to regional climatic cycles such as the East Asian monsoon and orbital-scale forcing like Milankovitch cycles. The cave’s depositional sequences preserve geochemical proxies—oxygen isotopes, carbon isotopes, trace elements—that connect to records from other sites such as speleothems from Heshang Cave, marine sediments in the South China Sea, and loess deposits on the Chinese Loess Plateau.
Local knowledge of the cave precedes formal exploration; modern speleological work expanded during the 20th century with contributions from Chinese geological surveys and international collaborations involving researchers affiliated with institutions in Beijing, Shanghai, and universities such as Peking University and Nanjing University. Systematic mapping and sampling campaigns employed uranium–thorium dating, stable isotope analysis, and uranium-series methods pioneered by teams associated with the Chinese Academy of Sciences and foreign research centers. Development into a show cave involved infrastructure improvements, lighting installations, and pathways overseen by local authorities in Lingui District and tourism bureaus from Guilin Municipal Government.
Dongge Cave stalagmites have provided some of the most detailed paleoclimate records for late Quaternary East Asia. High-precision uranium–thorium dating on stalagmite samples produced chronologies spanning glacial–interglacial transitions, including abrupt climate events synchronous with records from Greenland ice cores and North Atlantic proxies. Oxygen isotope variations in the cave deposits are interpreted in the context of changes in the East Asian summer monsoon, and comparisons have been made with marine isotope records from the South China Sea and terrestrial sequences from the Chinese Loess Plateau. Research teams from institutions such as the Institute of Tibetan Plateau Research, Chinese Academy of Sciences, and international collaborators have published work linking Dongge records to episodes like the Younger Dryas and Holocene monsoon fluctuations, contributing to debates on climate teleconnections involving the Indian Ocean and Pacific Ocean.
Following development, the cave now functions as a show cave with guided routes, interpretive signage, and facilities managed by local tourism enterprises and the Guilin Tourism Administration. Visitor amenities include pathways, lighting systems designed to minimize lampenflora, ticketing, and safety features to accommodate domestic tourists from Shanghai, Beijing, and nearby provinces as well as international visitors. The cave’s proximity to Guilin’s scenic attractions such as the Li River and limestone peaks in Yangshuo integrates it into regional tour circuits promoted by travel agencies and hospitality operators in Guangxi.
The cave contributes to the cultural landscape of the Lingui area by featuring in regional tourism promotion and local heritage initiatives coordinated with municipal cultural bureaus. Income from cave tourism supports local employment in guiding, hospitality, and handicraft sectors, and links with transport hubs in Guilin Liangjiang International Airport and rail connections to cities like Nanning and Guangzhou facilitate visitor flows. Scientific prominence has also enhanced the cave’s profile, fostering partnerships between research institutions and local government that channel funding into conservation and community development projects associated with the broader South China Karst World Natural Heritage context.
