Detian waterfall

Home Scenery 2018-12-12

Detian Waterfall is located in Detian Village, Shuolong Town, Daxin County, Chongzuo City, Guangxi Zhuang Autonomous Region. It is located in the upper reaches of Guichun River on the border between China and Vietnam. The waterfall is magnificent and magnificent. It is connected with the adjacent Vietnamese Banyue Waterfall ("Bn Gi C & C Thin"), the largest waterfall in Asia and the fourth largest waterfall in the world. It is about three times the amount of Huangguoshu Waterfall in Guizhou, and it is the national AAAAA tourist attraction in China. Or the location of Wine is Hometown Alcohol and Flowers and Bones, which is magical and wonderful.

In January 2016, the State Tourism Administration and the Ministry of Environmental Protection intend to designate the Dadetian Scenic Area of Chongzuo City, Guangxi Autonomous Region, as a national ecotourism demonstration area.

On October 17, 2018, the Ministry of Culture and Tourism publicized nine national 5A scenic spots, including Detian Falls.

Geological formation

Detian Waterfall is located in the middle Devonian dolomitic limestone, which is a typical karst waterfall. The upstream is the Guichun River flowing through Vietnam, which is a braided channel with wide and shallow riverbed and many rivers in Xinzhou and Xintan. When approaching Detian Waterfall, the height difference between the river bed at the lower reaches of the waterfall and the river bed at the top of the waterfall is about 6 meters. In order to find the shortest path to the water surface at the lower reaches, the flow of Guichun River takes its way through the dolomite buds in the river bed at the upper part of the waterfall.

Shiya islands such as Putang Island were formed. These islands in the river divide the water into multiple streams, which flow from different parts to the precipice edge of the waterfall, resulting in multiple bundles of waterfalls.

Rock properties

The water-falling cliff of Detian Waterfall lies in dolomitic limestone of Middle Devonian Donggangling Formation, while the bottom of the water-falling is clastic rock strata of lower Devonian gray-green, yellow-green and yellow-brown, such as siltstone, argillaceous siltstone and shale. Clastic rocks such as siltstone, argillaceous siltstone and shale have poor erosion resistance and are easily eroded by water flow, while dolomite has strong erosion resistance, and the slope composed of thick dolomite is stable. Although dolomite can be eroded by water, its dissolution rate is slower, far less destructive than that of water flow. And the solubility of dolomite itself is not very strong.

In addition, dolomite is more resistant to erosion than sandy shale. Waterfall flow erodes the base of the cliff and holes the bottom of the cliff, which leads to the collapse of the cliff. Therefore, the cliff retreats more in the most concentrated part of the water flow (mostly in the middle of the waterfall), and so does Detian Waterfall, such as the formation of the middle part of the fourth-grade waterfall cliff. The same is true for the first waterfall.

Strata characteristics

Located on the West Wing of Sichengling anticline, Guichunhe River is controlled by NW-SE trending structures, and NE-SW trending faults are also active nearby. Under the influence of these faults,

Joint fissures of thick dolomite with gentle occurrence (5-8 degrees) are developed. Joint fissures are used by water flow as its own migration channel, and these fissure surfaces are enlarged to form steep cliffs along the fissure surface. In addition, because there are some layers of fissures in the strata, the upper rock mass is easy to be destroyed, thus forming multi-level cliffs and waterfalls.

At Detian Waterfall, dolomite is situated on the upper part of siltstone with poor erosion resistance and the upstream of the first water crossing. At the same time, the occurrence of the strata is gentle, which makes the flow more stable distribution on the falling cliff surface. It is easy to form waterfalls with relatively wide water surface, such as Detian Waterfall.

Structural characteristics

The natural slope of Guichun River Valley is larger. The flow from Putangdao to Niandi Hydropower Station in the upper reaches of Detian Falls is 18.93 km. The water level falls 190 meters, and the hydraulic slope falls 1%. Small falls are formed in many places of the valley. The river flow is fast, and the erosion of the river bottom is very strong, which is conducive to the formation of waterfalls. Detian Waterfall Cliff was originally a fissure point on the river, and gradually developed into a magnificent waterfall due to the difference of lithology.

discharge

Guichun River has a large volume, with an average annual discharge of about 50 cubic meters per second. It has a strong erosion effect on the riverbed and is beneficial to the formation of waterfalls.

Morphological character

Guichun River has a rainfall catchment area of about 2200 square kilometers, of which 505 square kilometers are distributed in Vietnam, with an average annual flow of 55.20 cubic meters per second. The river bed of Guichun River falls 243 meters. The largest one is Detian Waterfall, which forms the fourth natural waterfall. Detian Waterfall is 100 meters wide, divided into three cascades, with a vertical height of more than 70 meters. It originates from Guichun River in Guangxi and has water all year round. Detian Waterfall is connected with Banyo Waterfall in Vietnam. During the rainy season, the two waterfalls are integrated, with a width of 208 meters.

natural environment

Detian Falls is located in the upper reaches of Guichun River in Daxin County, about 50 meters from the No. 53 boundary marker on the Sino-Vietnamese border. The clear Guichun River is the tributary of the Zuo River and the border river between China and Vietnam. Detian Falls is its masterpiece when it flows through Putang Island. The mighty Guichun River rushes from the north, and Putang Island, a high cliff with three layers, stands tall and stands tall, blocking the river flow. The river falls down from the cliff as high as 50 meters, hits the hard stone, splashes in all directions, mists in the water, looks like silk hanging in the sky from afar, looks like flying pearls splashing jade in the near, through the sunshine refraction, colorful, that is. The sound of the water and the oscillation of the valley are very powerful. The waterfall falls in three stages, with a maximum width of more than 200 meters, a depth of more than 60 meters, a drop of more than 70 meters, an average annual flow of 50 cubic meters per second, and its geological location is thick layered dolomite. It is the largest natural waterfall in Southeast Asia and has been designated as a super scenic spot by the state. It is connected with Banyo Falls in Vietnam, like a pair of close sisters. The border people of China and Vietnam are carrying on the frontier trade downstream of the waterfall, once shoulder-to-shoulder.

Historical culture

In a place bordering Guangxi Zhuang Autonomous Region in southwestern China and Vietnam, a clear river has flowed since no matter when it is cold or hot in all seasons. She is always green and clear, as simple as a girl in the mountains. People have given her a beautiful name, Guichun River.

Guichun River flows quietly to Vietnam and then back to Guangxi. Finally, in the border town of Shuolong, after a long period of silence, the power bursts out in an instant, breaking through thousands of rocks and mountains, breaking through the blockade of high cliffs and green trees, and falling thousands of miles, the border between China and Vietnam is delimited. Maybe it's the creation of nature. The stubborn river water falls down from the cliff as high as 60 meters, hitting layers of rocks, tortuous currents, splashing water and mist. It looks like silk hanging in the sky. It looks like flying pearls splashing jade. Through the refraction of sunlight, it's colorful. The noisy sound of water, oscillating River valley, is inadvertent. In the meantime, another fascinating miracle has come into being: Detian Falls, the fourth largest national waterfall in the world and the first large-span waterfall in Asia. Therefore, Detian Falls has been the most passionate expression of Guichun River since the day it was created.

Detian Falls and Banyo Falls in Vietnam are integrated, like a pair of close sisters, curling Tingting, standing hand in hand. Looking through the mist, I suddenly saw Yiren, on the water side, wrapped around the spring river like a jade belt, drooping her hair to the Chaohu Lake, leaning on the strange peaks and rocks, backing on the ancient wooden terraces, smiling and looking forward to love. This is really a poetry of romance and elegance, step by step is the scene, everywhere sentimental. Among them, if the painting is in the middle, the heart is free from distractions, and there is no dust. I just want to find a place where the green grass is growing and the green current is rippling, build a thatched house, plant several peach trees, plow several mu of land, and see that when the flowers are in full bloom and the branches are burning, I will imitate the elegance of the talent of Tang Dynasty, the hand of the handler, and form a hermit relationship with the branches of wine and flowers.

Tourist route

Self help tour

1. Every morning at 9:00 a.m., there is a special tourist express bus departing from Nanning Langdong Station, which can go directly to the gate of the scenic spot. But time is limited and we have to go back at 3:30 p.m. If you can't catch up, you can transfer to Daxin County Bus Station.

2. Every day, there are many buses going to Daxin County at Nanning Beida Passenger Station, and then transfer to Detian Scenic Area after arriving at Daxin.

3. De antenna is a well-developed tourist route. The day tour with the group usually starts from 7:00 to 7:30 a.m. in Nanning. The price is about 200 yuan. It is convenient for the special bus to go directly to the scenic spot. The price of the two-day tour varies from more than 200 yuan to more than 500 yuan, both in full package and in half package. Generally, you will visit Mingshi Pastoral or Lingshi Grand Canyon on the basis of Detian Falls.

Self-driving travelling

Starting from Nanning, follow 324 National Highway (Fukun Line) westbound to Tanluo, turn left to Daxin direction, to Shuolong Town, and then go on for more than 10 kilometers. The road is bright and beautiful. There are also striking tourist signs on the roadside to show the way. Especially driving along the Heishui River, countless beautiful scenery such as Mingshi Pastoral, Nabang Pastoral, Duxiu Peak, Wuzhi Peak, Xianshan Yaochi, Shuishui Stone Forest are known as "Qunyinghui Detian", which gives people a real feeling of walking in the landscape gallery.

Ticket Price

Adult fare: 80 yuan per person; Children: 1.2m-1.4m: 50 yuan per person, free of charge below 1.2m; Daxin Local Tourist Ticket: 10 yuan.

Tour time

The best time to visit Detian Falls: June - November every year, because of the rainy season, there is a large amount of water and clean water, which is the best time to appreciate the roar of the waterfall. Detian Falls has abundant water in summer and abundant vegetation around it.

The period from December to May of next year is dry season. During this period, the amount of water in the waterfall is small, and the earth and rocks around the waterfall are more exposed, so the ornamental effect will be greatly reduced.

Honors

On October 23, 2005, the list of the most beautiful places in China was published in Beijing. The event, sponsored by National Geography of China and co-sponsored by 34 media organizations in China, lasted eight months. Three categories of awards were awarded: Expert Society Group, Media Congruence Group and Network Mobile Phone Population Group. "Media group" and "popularity group" respectively produce 12 award-winning places by means of media voting, netizens voting and mobile phone users voting. The group of expert societies awarded by China National Geographic Magazine has a unique style, which is divided into 15 types: mountains, lakes, forests, grasslands, deserts, Yadan landforms, islands, coasts, waterfalls, glaciers, canyons, urban areas, rural towns, tourist caves, marshes and wetlands. Detian Falls is one of the six most beautiful waterfalls in China.

On October 17, 2018, the National Tourism Resources Planning and Development Quality Assessment Committee announced that nine scenic spots such as Detian Transnational Falls in Chongzuo City would be designated as national 5A-level scenic spots.
