The Three Gorges flows thousands of miles in spring, and then flows into boudoir.
3. The boulder rushes to the cliff, pointing to the afterlife, and Hinami rises in the middle of the string. At first, people suspected that the spewing contained thunder wind.
4. The high gorge flows out of Pinghu, cutting off Wushan Yu Yun.
5. It twists and turns, and the smoke locks the mountain peaks into the painting screen.
The Yarlung Zangbo Grand Canyon is the deepest canyon on earth. According to the information released by the State Bureau of Surveying and Mapping, the Grand Canyon starts from Daduka Village, Pai Town, Milin County (at an altitude of 2,880 m) in the north, passes through the Yarlung Zangbo River bend in Pailong Township, and ends at Pasigat Village, Medog County in the south (at an altitude of 1 15m, near Assam in southern Tibet), with its main body in Medog County. With a total length of 504.6 kilometers, the deepest point of 6009 meters and an average depth of 2268 meters, it is undoubtedly the largest canyon in the world. It is much larger than the Palong Zangbo Grand Canyon, the second largest in the world, the Colorado Grand Canyon in the United States (2133m deep and 370km long) and the Colca Grand Canyon in Peru (3,203m deep and 90km long). There are four rare waterfalls on the canyon riverbed in the no man's land at the core of the Grand Canyon, some of which fall by 30-50 meters. There are nine vertical natural zones in the canyon, ranging from alpine ice and snow to tropical rain forests in low valleys. It is home to various biological resources, including 2/3 of the known higher plant species in the Qinghai-Tibet Plateau, 65,438+0/2 of the known mammals, 4/5 of the known insects and 3/5 of the known macrofungi in China.
Yarlung Zangbo Grand Canyon (also known as Yarlung Zangbo Grand Canyon) is the deepest, longest and highest-altitude grand canyon in the world. Announced to the world at 1992. Because the peaks and valleys are close at hand, the strong terrain contrast of several kilometers constitutes the first magnificent landscape in the world. [ 1]
Yarlung Zangbo Rive Canyon
The Yarlung Zangbo River Grand Canyon is the largest water vapor channel in the Qinghai-Tibet Plateau. According to the conclusion of scientific investigation, the Yarlung Zangbo Grand Canyon was formed by Himalayan movement and river erosion. The Yarlung Zangbo River Gorge not only ranks first in depth and width in the world, but also attracts the attention of scientists all over the world with its rich scientific connotation and valuable resources. The largest precipitation belt in the world is distributed in the natural zones of the Yarlung Zangbo River and the Yarlung Zangbo River Gorge, the northernmost tropical climate zone in the Yarlung Zangbo River basin. Therefore, this is the most ideal field laboratory to study the coupling between layers in the earth system.
The combination of peaks, bends and canyons is very rare in the history of world canyon river development, which is a natural wonder in itself. In fact, the Great Bend Canyon is made up of several bends. The Garabaire Peak on the north side of the canyon is also the center of glacier development, and the Liequ Glacier on its east slope is a large valley glacier, extending from the snow line to the altitude of 1850m.
On the northern slope of the eastern section of Nyainqentanglha Mountain at the mouth of the water vapor passage in the north of the Grand Canyon, there is a Kachin glacier, which is 33 kilometers long. Very long. The Laigu Glacier in the upper reaches of Palong Zangbo is 35 kilometers long. Part of them is a long-valley glacier in China ocean temperate glacier, and the last part of the glacier extends into subtropical evergreen broad-leaved forest, with the lowest elevation of about 2500m, forming a peculiar natural landscape.
In the 4th century, there were many glaciation in the mountains here, leaving a complete U-shaped ancient glacial valley. The dense ice mounds on the valley floor plain are like graves, which are the accumulation relics of ancient glaciers in the specific environment of water vapor passage. On the Qinghai-Tibet Plateau, the world-famous roof, there is a green channel extending southeast along the Yarlung Zangbo River-Yarlung Zangbo River Valley.
The annual precipitation is 4500 ~10070 mm; It is this natural water vapor channel that narrows the obvious difference between the north and south natural belts. 2. It is this natural water vapor channel that drives many thermal drives and plants to move northward. It is this natural water vapor channel that promotes the mixing and communication between the northern and southern creatures in the Himalayas, and it is this natural water vapor channel that provides a safe shelter for many paleontological species.
The Yarlung Zangbo River Grand Canyon is the region with the richest hydropower resources in the world. The river passes through the valleys of two high mountains at an altitude of more than 6000 meters, forming a strange U-shaped bend around Nangbawa Peak. The mountains are high and the valleys are deep, and the water is fast. Starting from the 496.3km downstream of pasighat, the water level of the river plummeted from 29 10m to 155m, with a natural drop of 2,755m and an average gradient of 5‰, ranking first among the major rivers in the world. Especially, the straight-line distance from Medog 2 12km reach is less than 40km, but the water level difference is 2230km, the average gradient is 10.5‰, and the annual average flow is1900m3/s. It is the most abundant and concentrated area in the world, and a hydropower station with an installed capacity of 40 million kilowatts can be built here.
