Karst landforms, karst landform characteristics

Jinyangwang refers to the common stone buds, stone forests, peak forests, karst ditches, funnels, sinkholes, sinkholes, dissolution depressions, slope valleys, blind valleys, underground karst caves, underground rivers and other cave systems on the surface of the limestone area, as well as stone stalactites, stalagmites, stone pillars, stone waterfalls and other landforms in the caves. For the above-mentioned unique landforms of the limestone area, the academic circles at home and abroad are named after the place name of the karst landform plateau in the typical limestone landform area of Yugoslavia, that is, "karst landform". In the past, the term "karst landforms" was also used in China.

In China, the distribution area of karst landforms is about 1.3 million square kilometers. It is mainly distributed in Guangxi, Guizhou, Yunnan and other provinces and regions, such as Guilin landscape in Guangxi, Lunan Stone Forest in Yunnan, etc., and Yingde Yingxi Peak Forest in Guangdong, Yanziyan in Qiaotou Town, Huaiji Qiaotou Town, Zhaoqing Qixing Rock, etc. (Wen Liang Yiqi).

Karst landforms (karst landforms).

Karst landform is a landform formed by chemical dissolution of soluble rocks (carbonate rock, gypsum, rock salt) by water.

Karst is the place name of the limestone plateau of the Istellian Peninsula in northwestern Yugoslavia, at the end of the 19th century, the Yugoslav scholar Si Weijie (first studied the area, and borrowed the word karst as a general name for the phenomenon of a series of processes in the limestone area, and in 1966 the second Catat academic meeting in China suggested that the word "karst" be changed to "karst". Therefore, karst landforms are also called karst landforms.

The karst landform is often rugged on the ground, the rocks are craggy, and the strange bees are numerous, and there are common forms such as stone buds, stone forests, peak forests, karst ditches, funnels, sinkholes, and dissolution depressions on the surface; Underground, underground rivers and karst caves are developed. There are colorful stalagmites, stalactites and stone pillars in the cave, which are beautiful.

China's karst landforms are widely distributed, mainly concentrated in Guangxi, Yunnan, Guizhou and other provinces and regions, such as the beauty of mountains, stones, water, caves in Guilin, Guangxi, and the Lunan Stone Forest in Yunnan are famous all over the world.

"Karst" (kras) was originally the name of the limestone plateau on the Istrian peninsula in northwestern Yugoslavia, where typical karst landforms developed. The word "karst" is synonymous with karst landforms.

Karst landform refers to various landforms formed by the dissolution of soluble rocks by water and accompanying mechanical action, such as stone buds, stone ditches, stone forests, peak forests, sinkholes, funnels, karst depressions, karst caves, underground rivers, etc. In the karst landform development area, the ground is often full of strange peaks, and the surface water system is relatively lacking, but the underground water system is relatively developed. Guangxi, Guizhou, Yunnan and other places in China are widely distributed karst landforms, which are one of the most typical areas in the world.

<>1. Dissolution ditch: surface water dissolves along the joint plane or fracture surface in the limestone, and the limestone originally distributed in layers is separated into stone pillars or stalagmites by the karst ditch.

2. Sinkhole: surface water seeps and dissolves more than 100 meters deep along limestone cracks.

3. Karst cave: lateral flow occurs after the groundwater falling from the sinkhole to the aquifer.

4. Collapse funnel: with the formation of underground caves, the surface collapses.

5. Poli Valley and Tiansheng Bridge: The long-term combination of groundwater dissolution and subsidence action.

6. Wadi valleys and stone forests: the ground rises, and the original karst caves and underground rivers are lifted out of the surface. For example, Guilin's Elephant Trunk Mountain was formed by the outcropping of the original underground river.

Karst landforms are karst landforms.

Karst landform is a general term for the surface and underground forms formed by the dissolution of soluble rocks by water with dissolution power, named after the karst plateau of Slovenia, also known as karst landform in China, and is one of the five major modeling landforms in China.

Karst landforms are divided into two categories: surface and underground, and there are stone buds and dissolution ditches, karst funnels, sinkholes, dissolution depressions, karst basins and karst plains, peak clusters, peak forests and solitary peaks. There are karst caves and underground rivers and dark lakes underground.
