To see the karst landform, what places at home and abroad are worth visiting?

Among the many karst landscapes, I mainly recommend these three.

1. The stone forest in Guilin, Guangxi

Guilin's landscapes are the best in the world, indicating that Guilin's landscapes are on an equal footing, such asIf it is said that the water in Guilin is gentle and affectionate, then the mountains of Guilin are tenaciousMountains rise from the ground, like bamboo shoots in spring, majestic as if to touch the clouds, dense and dense, handsome and straight, and like a soldier guarding the Li River, sitting on a bamboo row floating in the Li River, stirring up ripples, watching the beautiful stone forest reflected on the green like jade on the river surface, making people intoxicated.

2. Yunnan Stone Forest

The area of the stone forest here is very large, there are two scenic spots of large stone forest and small stone forest, and the whole area is more than 350 square kilometers. The stone pinnacles are layered on top of each other, strange and strange, upright and abrupt, connected and overlapped, one after another; The strange-shaped stones, one after another, are dizzying. Nature is ingenious enough to create this miracle on earth, and it is truly a veritable rocky forest.

Walking in the stone forest, all the way to the lake and mountains. On the side of a pool of blue waves, a peculiar stone peak protrudes from the flat ground, and the side view looks like the figure of a girl with a basket. It's really nice to come here to relax and relax!

3. Chongqing Longshui Gorge crack

Longshui Gorge cracks, surrounded by lush forests, the tall bamboos, showing the beauty and backbone, the clear water pours between the canyons, the clear water penetrates the heart and cools, brushes away the surrounding heat, and makes your hot heart instantly calm; Looking up, the mountains on both sides are towering, and when you stroll through it, you will see the vibrant pothosAt every corner, you may encounter unexpected scenery, and there are surprises everywhere.

In fact, there are many similar attractions, you have to find them all the way, if you have time, go to have fun, and meet a different kind of yourself!

Sichuan Jiuzhaigou travertine beach flow, Zhejiang Yaolin Wonderland, Yunnan Lunan Stone Forest Scenic Area, Guangxi Reed Flute Rock, etc.

Located in Lincheng County, Xingtai, Hebei Province, "Kongshan Baiyun Cave" is one of the largest karst caves in northern China, known as "the first cave in the north". On the gate of the scenic spot, "Kongshan Baiyun Cave" is inscribed by Mr. Zhao Puchu, president of the Buddhist Association of China.

Guilin Landscape, Yunnan Stone Forest, Chongqing Wulong's Tiankeng, Tiansheng Bridge, Guizhou Libo Water Forest, and Jiuzhaigou are all very good choices.

If you want to see the karst landform, go to Guilin, Guangxi, where there are no high-rise buildings, only high mountains of different shapes, which is a typical karst landform and is worth checking in.

Karst landforms are widely distributed in Guangxi, Yunnan and other places in China. Famous tourist attractions in China include Yuhua Cave in Jiangle County, Kunming Stone Forest Scenic Area, Jiuzhaigou in Guizhou and so on.

Sichuan Jiuzhaigou must go In fact, Guilin also has it If you want to see the landform, the Grand Canyon abroad is very famous, it is recommended to go to see the mountain, which is better than a simple landform.

To see the karst landform, it is recommended to go to Guilin, Guangxi, and the famous scenic spots include the Li River, Seven Star Rock, Ten Mile Gallery, Xiangshan Park, Nine Horse Painting Mountain, etc

Located in the Mengyuan Wonderland of Xishuangbanna Tropical Rainforest National Park in Yunnan Province, the karst cave group is a treasure of tropical rainforest left at 21 degrees north latitude, with a unique karst landform, showing the magic of nature.

There are many factors that are not conducive to production in karst areas that need to be overcome and prevented, and there are also a large number of factors that are conducive to production that can be developed and utilized. When selecting the site of the reservoir dam, faults, fracture zones and karst landforms should be avoided as much as possible.

Wait. 1. As an unstable landform, it has a huge impact on the construction of buildings and roads. This has become an important factor restricting the local economic development.

2. The problem of soil erosion is serious, and the direct consequence is the serious loss of soil organic logistics and the barren land, which seriously hinders agricultural production.

Formation: Southwest China.

The main reason why karst landforms are widely distributed is that there is the main body of its development. A large number of carbonate rocks, sulfate rocks and halide salts have formed various strange karst caves on the surface and underground under the continuous dissolution of flowing water.

This wonderful natural action is used in chemical equations.

It can be manifested as: CaCO3 + CO2 + H2O = Ca(HCO3)2. Dissolved calcium bicarbonate.

If the water is heated or the surrounding pressure suddenly becomes smaller, the dissolved calcium bicarbonate in it will decompose and turn back into calcium carbonate.

deposited, the reaction equation is: Ca(HCO3)2 = CaCO3 +CO2 +H2O.

The southwest region has a humid climate with precipitation.

The surface runoff is relatively stable, the infiltration of flowing water is continuous, and the precipitation makes the flowing water renew and effectively replenish, so the karst process can be continued.

Because of its diverse shapes and landforms, the karst landform has high aesthetic value, and many karst landscapes have been developed into tourist attractions, such as Yunnan Stone Forest, Guizhou Libo, Chongqing Wulong, Chongqing Jinfoshan, Guizhou Shibing, Guangxi Guilin and Huanjiang, which are jointly included in the World Natural Heritage List as "South China Karst".

The karst cave is a safe place to shield the orange oak from radioactive radiation, which can not only protect the important archives and materials of the country in times of war, but also protect the precious lives of soldiers and civilians. In terms of the many caves in the three provinces of Yunnan, Guizhou and Guizhou, the large ones can accommodate tens of thousands of soldiers and civilians, and the small ones can also be counted by thousands.

China's Yunnan-Guizhou region was not covered by large glaciers during the Quaternary Ice Age, and became a refuge for many ancient flora and fauna. The landform area of the karst stool is complex and the habitats are diverse, so the human interference to the environment in the area has been small for a long time, and the species in the Yunnan-Guizhou area have been intact.

The Fanjing Mountain in the region is also included in the United Nations Man and Biosphere Nature Reserve Network and the World Natural Heritage List. Libo Maolan Karst Forest Nature Reserve still preserves the most intact karst primeval forest in the same latitude, with a forest coverage rate of more than 90%.

At the end of 1994, the Beijing Astronomical Observatory (now the National Astronomical Observatories of China) led 20 colleges and universities in China to propose the construction of "Kass Cheng". The final site was selected in Dawotai, a large sinkhole in Guizhou Province with stable geological conditions, large-diameter sinkholes and lack of radio interference. The FAST radio telescope, the world's largest single-aperture radio telescope, was finally completed in Pingtang County, Guizhou Province on September 25, 2016, and is known as the "Eye of China".

In addition, the karst landform has abundant groundwater resources, buries a large number of paleontological and ancient human fossils, or becomes a good place to store bauxite, placer ore and oil and gas, so the karst landform has great scientific research significance and production value.

Karst landforms are widely distributed in the world, and the main distribution areas are: the Dinara Mountains of Yugoslavia, the Plateau of France, the Ural Mountains of the Soviet Union, the southern part of the Australian and Hudalian continents, Kentucky and Indiana in the United States, Cuba, Jamaica and northern Vietnam. China's karst landforms are also widely distributed, Guangxi, Guizhou, Yunnan and other places are widely distributed karst landforms, which is one of the most typical areas in the world.

Karst landform is a general term for the surface and underground forms formed by the dissolution of soluble rocks by water with the erosive power of dissolved rocks. Also known as karst landforms.

Solubility of rocks.

Karst landforms can be divided into many types, such as Guilin Shanshui belongs to Fenglin Karst, Guilin Qixingyan belongs to Sinkwater Cave Karst, Sichuan Huanglong belongs to travertine karst, Yunnan Stone Forest belongs to Ronggou Karst, etc. The fundamental reason for the formation of karst landforms lies in the solubility of the rocks, which are mostly limestone.

According to China's Gansu network, the insoluble calcium carbonate in the limestone can be converted into slightly soluble calcium bicarbonate under the action of water and carbon dioxide.

In addition, the influence of climate on karst landform is also obvious, such as the humid climate in southwest China, the precipitation is large, the surface runoff is relatively stable, and the infiltration of flowing water is continuous, so karst can be continued.
