The three rivers running side by side are Jinsha River, Lancang River and Nujiang River, three rivers originating from the Qinghai-Tibet Plateau, running 170 kilometers from north to south in Yunnan Province, crossing the mountains of Danglika Mountain, Gaoligong Mountain, Nushan Mountain and Yunling Mountain. The upper part of the three parallel rivers is in southeastern Tibet and the lower part is in Yunnan Province.
It forms a peculiar natural and geographical landscape which is rare in the world, where rivers and rivers flow side by side but do not converge. The shortest straight line distance between Lancang River and Jinsha River is 66 kilometers, while the shortest straight line distance between Lancang River and Nujiang River is less than 19 kilometers.
The natural landscape of three parallel rivers is composed of Nujiang, Lancang, Jinsha rivers and mountain ranges in their basins, covering 1.7 million hectares. It includes 9 nature reserves and 10 scenic spots located in Lijiang, Diqing Tibetan Autonomous Prefecture, Nujiang Lisu Autonomous Prefecture in Yunnan Province. Located at the intersection of East Asia, South Asia and Qinghai-Tibet Plateau, it is a rare representative area of Alpine landform and its evolution in the world, and one of the most abundant areas of biological species in the world. The scenic spot spans Lijiang, Diqing Tibetan Autonomous Prefecture and Nujiang Lisu Autonomous Prefecture.
The three parallel rivers area is the richest geological and geomorphological Museum in the world. Forty million years ago, the collision between the Indian plate and the Eurasian plate triggered the sharp compression, uplift and cutting of the Hengduan Mountains. Alpine mountains and rivers alternately spread, forming the world's unique natural wonder of three rivers running 170 km parallel.
In 1988, with the approval of the State Council, "three rivers running side by side" was designated as the second batch of national scenic spots. In July 2003, according to the selection criteria of natural heritage, it was listed in the World Heritage List , and constructed the Three Rivers Parallel Nature Reserve (mainly the Three Rivers Parallel Nature Reserve in Yunnan Province).

Geology and geomorphology
The "Three Rivers Parallel Flow" region is an outstanding representative of the main stages of the Earth's evolution, which reflects the rich and diverse geological relics, landscapes and geological phenomena, and shows the world the extremely complex history of crustal evolution and the ongoing geological role it has experienced.
The relatively complete paleobiostratigraphic records since the Late Paleozoic (400 million years ago) in the "Three Rivers Co-current" area reflect that the area was once a part of the vast Tethyan paleo-ocean, consisting of ultrabasic rocks (such as ophiolite, peridotite), basic rocks (such as gabbro, diabase, pillow basalt, spilite, etc.) and deep-sea deposits (such as radiolarian siliceous rocks). The composition of ophiolite reflects that this area was once similar to the present oceanic crust environment near the mid-oceanic ridge; the magmatic rocks (including volcanic rocks, hypabyssal rocks and plutonic rocks) of various types and compositions recorded the scale and characteristics of magmatic activities in different periods, reflecting the evolution model of different stages; the metamorphic rocks, melanges, tectonites and strata, rocks in this area. Structural deformations such as folds, faults, joints and cleavages in the rocks and deep and large fault systems between different blocks reflect the intense compressive activities that have been suffered here. Geological and historical processes such as the extinction of the oceanic crust, the compression of strata, the assemblage of blocks and the uplift of the crust have become clear in the interpretation of many information by geologists: "Three parallel rivers" area is the evolution and extinction of the Tethyan Ocean, the collision of the Indian plate and the Eurasian plate, the land-land collision between the two continents, and the orogenic movement has resulted in the formation of the Himalayan uplift and the Hengduan Mountains. Typical representative areas and key areas of geological evolution history.
In the history of the earth's evolution, the ocean always opens and closes in the crustal movement. The opening of the ocean will lead to the separation of land on both sides of the ocean crust, while the closure of the ocean will drive the convergence of land on both sides of the ocean crust. The Tethyan ocean has undergone different processes of opening and closing, leaving many geological traces of strata, rocks, fossils and crustal deformation that prove the process. The closure of the Tethys ocean eventually drives the Indian plate to rush towards the Eurasian plate, making the "three parallel rivers" region evolve from deep-sea ocean environment to oceanic island arc and multi-island oceanic basin environment, then to continental environment and plateau environment. The strong compression of the two continents crushes, crumples and metamorphoses the rocks here, and triggers large-scale magmatic activities. Continuous collision activities have caused large-scale uplift and strong tectonic deformation in this area, resulting in the formation of the world's most compacted and narrowest compression of the giant Hengduanshan composite orogenic belt, that is, the unique "three rivers parallel flow" spectacle in the world.
Various and complex geological and tectonic settings have laid the foundation for the formation of various geomorphological types in the "Three Rivers Parallel Current" area. The tall folded mountain systems and fault-block activities control the dynamic geology of the surface, erosion moulding of rivers, erosion of mountain glaciers, and carve out deep canyons, glacial valleys, glacial lakes, waterfalls, corner peaks, fin ridges, peaks and cliffs, creating the geological and geomorphological landscape areas with the world's first-rate aesthetic feeling. The typical landscapes of "Three Rivers Parallel Flow" include "Three Rivers Parallel Flow" spectacle composed of alpine canyons, glacial relics and modern glacial landscapes, alpine Danxia landscapes, granite peak cluster landscapes, Alpine karst landscapes and plateau, snow mountains, meadows, Alpine glacial erosion lakes and so on.
Complex, diverse and special geological evolution history, geological landform and geographic environment characteristics control the origin of primitive biological population and the distribution characteristics of hydrothermal conditions in the "Three Rivers Parallel Flow" area, and then control the biological evolution process, characteristics and evolution model, forming a diverse biological and ecological landscape.
The diverse rock types, geological structures and landscapes of the "Three Rivers Parallel Flow" provide typical traces for the interpretation of the important historical stages and important geological events of the Earth's evolution, such as the extinction of the Tethys ocean, the collision mechanism and model between the Indian plate and the Eurasian plate, the formation of the intracontinental mega-composite orogenic belt, the evolution and uplift of the Qinghai-Tibet Plateau, and show the ongoing process. The magnificent processes of topographic and geomorphological shaping, such as various dynamic and glacial geological processes, are the outstanding development areas of various types of Alpine landscapes and their evolutionary processes. These precious and rare geological and geomorphological landscapes and relics are the common wealth left by nature to mankind, and have very important world significance and protection value.
This region is of great value in showing the geological history associated with the collision of the Indian Ocean plate and Eurasian plate over the last 50 million years, the closure of the Paleo-Mediterranean and the uplift of the Himalayas and Tibetan Plateau. These are major geological events for the evolution of the Asian continent's surface and the changes that are taking place. The diversity of rock types in this region records this history, and karst topography, granite monoliths and Danxia sandstone topography in the alpine belt cover some of the best mountain types in the world.
The exciting ecological processes in the three parallel rivers region are the result of geological, climatic and topographic influences. Firstly, the region is located in the active area of crustal movement, resulting in a variety of rock beds, ranging from igneous rocks to various sedimentary rocks (including limestone, sandstone and conglomerate). Excellent geomorphology: from canyons to karst landforms to ice peaks, this wide range of landforms is related to the collision point of crustal tectonic plates. Another fact is that the area is a Pleistocene reserve for remnants and is located in a biogeographic convergence area (i.e., with mild climate and tropical elements), which provides a good physical basis for the evolution of high biodiversity. In addition to topographic diversity (with a nearly vertical steep slope of 6,000 meters), the monsoon climate affects most of the region, thus providing another favorable ecological factor for the good development of temperate biota in various Palaearctic regions.
"Three rivers flow side by side" area is known as "the world biological gene bank". This area accounts for less than 0.4% of China's territory, but it has more than 20% of the higher plants and 25% of the national animal species. National Protected Animals
77 species of rare and endangered animals, including Yunnan snub monkey, antelope, snow leopard, Bengal tiger and black-necked crane
National Protected Plants
Thirty-four species of Taiwania flousiana, Phyllostachys chinensis, Taxus chinensis, etc.
China and important regions in the Northern Hemisphere. 2\ 3 of the fauna in the nominated area belongs to endemic fauna or to the Himalayan-Hengduan fauna. The region is thought to have more than 25% of China's animal species, many of which are relic communities and endangered species. Many of China's rare and endangered animals live within the scope of the nominated areas. Among them, 80 species are listed in the Red Paper of Chinese Animals, 20 of which are considered endangered; 79 species are listed in the appendix to the 1997 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES); and 57 species are listed in the appendix to the International Convention on the Protection of Nature and Natural Resources. IUCN's Red Paper on World Endangered Animals. Near the borders of the biogeographic regions of East Asia, Southeast Asia and Tibet, this region also provides a corridor for many species in each region to satisfy and reach their respective distribution boundaries. Most of the rare and endangered animals live in the western part of the region, especially in the narrow and long Gaoligong Mountains on the border of Myanmar and the Yunling Mountains between the Lancang and Jinsha Rivers.
In the 40 years from 1911 to 1950, F. Kingdon Ward, a British botanist and geographer, visited eight dangerous and difficult-to-reach secret lands in southeastern Tibet, northwest Yunnan and southwestern Sichuan. From April 1913 to March of the following year, Jindun Ward traveled through the three river basins of Jinsha, Lancang and Nujiang in the Hengduan Mountains bordering Sichuan, Yunnan and Tibet to investigate the river ownership, river system development, geology and geomorphology. He estimated that the ratio of annual runoff of Jinsha River, Lancang River and Nujiang River was roughly 5:3:2, and measured the distance between the three rivers below the "S" -shaped meander of Yuqu River. From the Nu River to the Jinsha River, the minimum distance was only 80.5 kilometers, making him the first person to discover the world's great geographic wonder that three great rivers parallel to each other in this section.
The natural landscape of "Three Rivers Parallel Flow" is located in the Longitudinal Valley of Hengduan Mountains in the southern extension of the Qinghai-Tibet Plateau. It consists of Nu River, Lancang River, Jinsha River and the mountain ranges in the basin. The whole area reaches 41,000 square kilometers. There are three scenic spots such as Nu River, Dulong River, Lancang River and Jinsha River, eight central scenic spots and more than 60 scenic spots, covering an area of more than 3500 square kilometers. The three rivers run parallel hundreds of kilometers in the longitudinal valley of Hengduan Mountains in Northwest Yunnan. The nearest straight line between the three rivers is 66.3 kilometers, of which only 18.6 kilometers are separated from the Nu and Lancang rivers.
Alpine snow peaks in the scenic area stretch across, and elevation varies vertically. From the 760-meter Nujiang dry-hot valley to the 6740-meter Kawagbo peak, there are snow mountains, primitive forests and ice-eroded lakes in the scenic area with different shapes. The main peak of Meili Snow Mountain, Kawagbo, is covered with glaciers for thousands of years. The glittering glaciers extend from the peak to the forest zone of Mingyong Village. It is the most spectacular and rare low latitude and low altitude monsoon oceanic modern glacier in the world.
The main landscapes are: peculiar "three rivers" flow side by side, magnificent mountains and snow peaks, dangerous canyons and beaches, beautiful forest, sea and snow plains, quiet ice-eroded lakes, rare plate collisions, vast snowy mountains and flowers, rich rare animals and plants, magnificent Baishuitai, unique national customs, which constitute the characteristics of majesty, danger, beauty, wonder, seclusion, Austria and sigh.
It is the largest area in Yunnan Province, with the richest landscape and colorful ethnic customs. It is a fascinating but undeveloped scenic spot. It was designated by UNESCO and approved by the State Council in 1988 as the second batch of national key scenic spots.
The collision between the Indian plate and the Eurasian plate caused the uplift of the Qinghai-Tibet Plateau, which constituted the main body of the Hengduan Mountains formed by the huge mountains such as Dulong River, Gaoligong Mountain, Nujiang River, Lancang River, Yunling River, Jinshajiang River and the great rivers within 150 kilometers. This is the unique mountain gorge in the world. Valley natural landscape. From the geodetic evolution of ophiolites, pillow lavas, geological strata records from biochemical to Quaternary to the metamorphic and deformed Glacial Snow peaks of intracontinental orogenic belts, cave rivers, karst landforms and so on, they fully meet one of the criteria for the nomination of the World Natural Heritage.
The three rivers run parallel and flow about 170 kilometers in Yunnan Province. They are located in Lijiang, Diqing Tibetan Autonomous Prefecture and Nujiang Lisu Autonomous Prefecture in the western part of Yunnan Province, with a total area of 40,000 square kilometers. The shortest straight line distance between Nu River and Lancang River is only 18.6 kilometers, while the shortest straight line distance between Lancang River and Jinsha River is only 66.3 kilometers.
The Jinsha River goes from north to east, bringing together the Yalong River, Minjiang River and Jialing River, so China has the Yangtze River.
The Lancang River flows slowly from north to south, crossing the border and becoming the upper reaches of the neighbouring Mekong River.
The Nu River rushes from north to south into Myanmar and becomes the upstream of the Salwin River.
The three rivers originated from the Qinghai-Tibet Plateau. They are running hand in hand in the mountains of Yunnan.
The Jinsha River, through Shigu Town's Tianjiao wonder (the first bay of the Yangtze River), turns sharply back to the east of the Yangtze River and finally flows into the Pacific Ocean.
The Lancang River flows through Myanmar, Laos, Thailand, Cambodia and Vietnam and eventually into the Pacific Ocean.
The Nu River flows into Myanmar and into the Indian Ocean.

Yunnan snub-nosed monkey is the most typical flagship species in the "three parallel rivers" region, and Baimangshan Snow Mountain Nature Reserve is the most concentrated one.
Mt. Kawagbo, the main peak of Mt. Meri Snow Mountain, is 6740 meters above sea level. It is the highest peak in the nominated area. Nobody has reached the summit successfully because of its unique topographic and climatic factors. Tibetan Buddhism has a strong religious color. The Mingyong Glacier, located at Kawagbo Peak, extends its tongue to 2650 meters above sea level. The surrounding green hills, conifers and broad-leaved mixed wet evergreen broad-leaved forest is well preserved, which represents the typical diversity of the Lancang River dry-hot valley. At present, it is the lowest glacier in the northern hemisphere and one of the lowest latitude glaciers.
Haba Snow Mountain Area
The area has the most southern latitude of modern marine glaciers, Jinsha River basin typical complete Alpine vertical natural landscape. Within a very small space, the vegetation types from subtropical dry and warm valleys to alpine and cold zones are concentrated. Cold-temperate coniferous forest is the most important ecosystem type in mountain ecosystem of Haba Snow Mountain Nature Reserve. It is characterized by rich and complex Chinese-Himalayan elements, and is the most typical Alpine coniferous forest reserve area of "World Heritage Nomination Site".
The main peak of Haba Snow Mountain is 5396 meters above sea level, which is one of the most famous extremely high mountains in Yunnan. There are modern glaciers on the top of the mountain. Like the glaciers in Yulong Snow Mountain, it is also the southernmost oceanic glacier in China. Alpine moraine lakes (Black Sea, Yellow Lake and Bay Sea) reflect the glacial relics formed by the accumulation of water in ancient ice buckets during the Dali Glaciation Period, and are the only "Dali Glaciation Period" glacial relics distribution area in the "Three Rivers Parallel Current" nomination site.
In 1988, the State Council approved the establishment of the "Three Rivers Parallel" National Key Scenic Spots; in 1993, the "Three Rivers Parallel" was officially listed in the preparatory list for China's declaration of world heritage; in 1998, the Yunnan Provincial Government put forward the strategy of "building a strong green economy province, a major national and cultural province, and connecting China with Southeast Asia through the creation of the world". Heritage brand promotes the development of Yunnan's tourism industry and decides to speed up the progress of applying for World Heritage by "three rivers running side by side". In that year, with the consent of the provincial Party Committee and the provincial government, the Yunnan Provincial Construction Department formally submitted applications to the UNESCO Committee and the Ministry of National Construction of China. The application for declaration has been supported and Yunnan Province has been approved to formally carry out the declaration work. On January 17, 2002, with the signature and approval of Li Lanqing, Wen Jiabao and Qian Qichen, the former Vice Premier of the State Council, the full committee of UNESCO, the Ministry of Foreign Affairs and the Ministry of Construction of China jointly issued a document agreeing that "three rivers flow side by side" would become the only declared project of World Heritage in China and be officially submitted to the UNESCO World Heritage Center.
From October 8 to 20, 2002, experts from the International Union for the Conservation of Nature (IUCN) made a field trip to the "three rivers parallel" area in Yunnan Province. In June 2003, the alliance recommended to the United Nations World Heritage Committee that "three rivers flow side by side" be included in the World Heritage List according to the four criteria of meeting all the World Natural Heritage Sites.
Scenic spot protection
In July 2018, the People's Government of Yunnan Province promulgated "Several Provisions on Strengthening the Protection and Management of World Natural Heritage Sites with Three Rivers in Parallel Flow in Yunnan Province", which will accelerate the ecological environment protection of the World Natural Heritage Sites with Three Rivers in Parallel Flow. The people's governments of the prefectures, cities, counties and districts where the three rivers are located should strictly control the intensity of development within the heritage sites and prevent In the heritage sites with three parallel rivers, construction of other engineering facilities is strictly prohibited except for the necessary protection facilities and public service facilities.
