Introduction

On both sides of the Yarlung Zangbo River Grand Canyon, the towering Nanjiabawa Peak (7782 meters above sea level) and Gala Bailei Peak (7234 meters above sea level) are all strong ascending fault blocks, standing tall and straight into the clouds. The glaciers hang over the peaks and mountains, and the clouds are misty.

From the air or from the mountain pass of Xixingla and other bird's-eye views of the Grand Canyon, among the countless snow peaks and green mountains of the Eastern Himalayas, the Yarlung Zangbo River cut out a steep canyon, crossing the high mountain barrier, and making a peculiarity around Nanjiabawa Peak The great turn of the southward dive into the Indian Ocean, its magnificent and peculiar.

The deepest part of the Yarlung Zangbo River Grand Canyon between Nanjiabawa Peak and Gala Bailei Peak reaches 5382 meters. It surrounds the core river section of Nanjiabawa Peak and has an average depth of about 5000 meters. The Grand Canyon of Colorado, the Colca Canyon at 3,200 meters deep and the Kriginge Grand Canyon at 4,403 meters deep.

The Yarlung Zangbo River Grand Canyon is the largest water vapor channel on the Qinghai-Tibet Plateau. Affected by the warm and humid air flow in the Indian Ocean, the annual precipitation in the southern section of the Grand Canyon is as high as 4000 mm and the northern section is also between 1500-2000 mm. Covered with dense forests, it forms the most biologically diverse canyon in the world. It is different from the arid Colca Canyon with desert vegetation and the more arid Colorado Canyon with a single pine forest.

The forests of the Yarlung Zangbo River Grand Canyon are lush. Due to the steep terrain, inconvenient transportation, sparsely populated, and many sections of the river are not populated at all, plus the Grand Canyon cloud cover fog, mysterious, so the environment is particularly quiet. This is also unmatched by the above three grand canyons.

The Yarlung Zangbo River Grand Canyon circumnavigates Nanjiabawa Peak in a continuous gorge, which is 496.3 kilometers long, 56 kilometers longer than the Grand Canyon of Colorado, known as the "longest" in the world.

Many of the sections of the Yarlung Zangbo River Grand Canyon are rocky on both sides of the river, and are simply impassable, so no one has ever walked through the canyon. Compared with the other three grand canyons, there are roads in the valley; Colorado Grand Canyon, visitors can travel through the valley with livestock; Colca Grand Canyon, visitors can travel along the valley; Kaligende Grand Canyon, the villages in the valley are dotted The trail along the valley is the main route for the development of local hiking tourism. As far as the water channel is concerned, the average flow of the Yarlung Zangbo River Grand Canyon reaches 4425m³ / s, far more than 67 cubic meters of the Colorado River and the other two rivers. The flow velocity of the river is as high as 16m / s. Close to the entrance of the Grand Canyon, the water surface fell at an altitude of 2910 meters and fell out of the Tibet Autonomous Region

It refers to Baxiqa at the lowest point of the Yarlung Zangbo River Grand Canyon, which is only 155 meters above sea level, far lower than any of the lowest points of the above three canyons.

The most bizarre of the Yarlung Zangbo River Grand Canyon is that it trails southwards from the east to the west in the Eastern Himalayas, and then along the southern slope of the Eastern Himalayas grabs its way down into the Indian Ocean to form the most bizarre horseshoe-shaped turn in the world. It is not only peculiarly peculiar in the landform landscape, but also a grand canyon with a unique water vapor channel in the world, creating a peculiar forest ecosystem landscape on the southeastern edge of the Tibetan Plateau.

The natural landscape of the entire Grand Canyon can be summarized by "Yaluzangbu River Grand Canyon Xiujia World". The so-called world of Xiu Jia mainly refers to the uniqueness in the show's breadth, depth and strength. In terms of breadth, the Grand Canyon is a mountain show, a water show, a tree show, a grass show, a cloud show, a fog show, a beast show, a bird show, a butterfly show, a fish show, a human show, a village show ... not only that, the Grand Canyon The show has its profound and majestic connotation. For example, the water of the Grand Canyon, from solid ice and snow to boiling hot springs, from trickle streams, curtain waterfalls to torrential rivers, solid, liquid, gaseous, snowflakes, streams, large rivers, beauty, and various forms of water, Various scales. In terms of strength, the waterfall of hundreds of meters, the velocity of 16m / s and the flow of 4425m³ / s are very spectacular. Like the Grand Canyon
