Water system composition

Buha River is the largest river in the Qinghai Lake Basin. It originates from the namujimuling mountain of shaguolin in Tianjun county and flows from south to East. It gradually turns from narizong in Tianjun county to Southeast and flows through Tianjun county and into Qinghai Lake near bird island. The main stream gradually widens and bifurcates below narizong, and there are 8 to 10 bifurcations near the estuary. The major tributaries flowing down from the source of the river are: iregai River, higerqu River, xiaergqu River, JUNHE River and jilmen river. Buha River has a catchment area of 14484 square kilometers, a length of 286.2 kilometers, an average annual discharge of 25.9 cubic meters per second, and an average annual sediment concentration of 0.64 kg per cubic meter.

JUNHE river is also called Jianghe, once called Junzi river. It originated from Datong mountain and caomandong mountain in Tianjun county. It flows through zhouqun Township and Jianghe township of Tianjun County, 8.4km below dajianghe township. RIHA River on the left bank flows into Buha River from northwest to Southeast. The JUNHE river has a catchment area of 3 073 square kilometers, 124.9 kilometers in length and an average annual discharge of 11.1 cubic meters per second.

The Gilman river is also called the gilmon river. It originated from Gongma mountain, GuLun County, Gangcha county. It flows from south to South and West, turns to Southeast and east near juerma, Tianjun County, and flows into Buha River through jilmeng Township, Gangcha county. Jilmen river has a catchment area of 1092 square kilometers, a length of 112.2 kilometers, and an average annual flow of 1.44 cubic meters per second.

survey

Buha River (buhaguole in Mongolian) is an inland river, located in the northwest of Qinghai Lake Basin in Qinghai Province, China. It originates from the north foot of mantan rigeng peak in the south of Shule mountain, a branch of Qilian Mountains. The source is 4600 meters above sea level. It flows from northwest to Southeast and flows into Qinghai Lake, the largest saline lake in China, in Quanji Township, Gangcha county. Buha River, with a total length of more than 300 kilometers and a drainage area of more than 16000 square kilometers, is the largest and longest river flowing into Qinghai Lake. The Buha River Estuary forms a 13 km Delta in the lake basin.

Natural characteristics

Buha River is just like a green silk ribbon, falling on the desert grassland. On the afternoon of lunch in Tianjun County, we were lucky to witness its beauty. Soon after leaving Tianjun County, the car arrived on a concrete bridge in about a quarter. The bridge is about 40 meters long, with smooth pavement and guardrails on both sides. Standing at the end of the bridge, we can see that on the flat wasteland, there are many shrubs and grasses, such as Salix, Salix, Salix, which are very prosperous and spread on the river beach. There are many pools of water, just like silver foil sticking between sand and pebbles, which are dazzling. There were white sheep and black Yaks in the bush. Occasionally, they saw one or two camels. Their yellowish fur was also shining in the green bush. They felt a little fresh. They stretched their necks and looked at us for a while, hissed twice, and then raised the smooth hump and gnawed grass.

The Buha River under the concrete bridge, like a quiet lady, sings in a low voice and laughs all the way. It flows from the distant wasteland to the nearby. Several streams of running water rush to the road and soon disappear in the dense bush. The current in the river is not very fast, but it is quite fast. The river is full of cobblestones. The big and the small are leaning against each other. They are horns of each other, just like brothers and sisters with deep friendship. The stones at the bottom of the river bed, square, round and flat, were different and colorful. At that time, the sun was shining and the light cut the bottom of the water, radiating golden light. Some water plants, hairless, just like the beauty of the bird's hair in the wind, wave after wave can not stop. Deep in the pool, the water is sparkling, reflecting the sand and stone under the water. A patch of rotten color, like a children's color painting, and like a landscape painting, is placed in front of your eyes, which makes people appreciate.

legend

It is said that a long time ago, the area to the west of Riyue mountain was a vast grassland. There were no mountains, no lakes, and no rivers on the grassland. There was only a clear, sweet, deep and bottomless spring. There was a big and heavy stone cover on the spring. No one could remove it. One year, a monk who went to the west to learn Buddhist scriptures passed by with his disciples. The apprentice was thirsty and wanted to find water to drink, but he couldn't find water everywhere. The monk told his apprentice: there is a spring in the middle of the grassland. There is a stone slab on the spring. If you open the stone slab, water will come out. After drinking water, be sure to cover the stone well. The apprentice went to drink water. The monk went first. After drinking the water, the apprentice was afraid that the master would go far away, so he got up in a hurry to catch up and forgot to cover the stone. He didn't go far, only to see the water rolling in behind him, and hurried back to cover, but it was too late. The monk didn't see his apprentice coming. Knowing that something was wrong, he rushed back. But it's too late, the grassland has become a vast ocean, and the water is still pouring up. The monk is in a hurry. A sword will cut off a nearby mountain. It was thrown into the water and held down the spring. As a result, a large lake is left here, and the half point on the spring comes out of the water, which is Haixin mountain in Qinghai Lake.

Beautiful legends leave people endless reverie. The magnificent Qinghai Lake is certainly not the "masterpiece" of the immortal family. It is the natural work of nature. The surging Buha River is the real "God of creation" of Qinghai Lake. Buha River is a mother river. It gave birth to the vast expanse of Qinghai Lake. The source of Buha River is shulenan mountain, with a total length of 228 kilometers, winding and winding. The annual water supply of Qinghai Lake is 4 billion cubic meters. Nearly half of them come from the Buha River. "Ask where the canal is so clear, only the source of water." (Zhu Xi's feeling of reading books).

basin

Buha River nourishes the grassland with green grass. The broad and gentle Buha River stretches its body quietly, with a drainage area of nearly 14000 square kilometers, accounting for almost half of the total area of Tianjun county. Many tributaries are generally distributed. The dew like river moistens the vast land and feeds Tianjun grassland, the largest natural pasture in Haixi area. "Wild flowers are charming, grass has no feet.". The vast Tianjun grassland is a paradise for Tibetan herdsmen to survive and multiply for generations.

whole story

Buha River originates from shulenan mountain, where there are snow capped peaks all the year round. The river valley stretches for more than 200 Li. At the foot of the mountain, there is a saltwater lake, called Hala lake, which is the size of two Kunming lakes. Buha River is not connected with it. It lies beside Hala lake, in the grass beach Valley, zigzagging three times to Yangkang, just like a slightly curved ribbon, straight Floating in Qinghai Lake. The water source of Qinghai Lake is mainly supplied by Buha River, which should be the lifeline of Qinghai Lake. I think that once the lifeline is interrupted, the world-famous Qinghai Lake may be in danger. If governments at all levels in Qinghai want to harness and protect the Qinghai Lake, I'm afraid they must first protect this lifeline.

trunk stream

According to the draft of Qing Dynasty history, "the hasixina river originates from the Kunan mountain of amunier in Northwest Qinghai, and the lower part is called Buha River.". Buha River is 218km long in Tianjun County, flows through Yangkang Township, kuairima Township and Tianpeng Township, and flows into Gonghe County and Qinghai Lake in tiebujia area of Tianpeng township. Its birthplace is 4350 meters above sea level, and its exit is 3260 meters above sea level, with a drop of 1090 meters. The beach is densely covered with shrubs, mainly black thorns, and the width of the riverbed is 0. 5-1 km. At the bottom of the river are large and small pebbles and mudstones.

Buha River and Qinghai Lake

brief introduction

Qinghai Lake is also known as "kukunor", which means "blue sea" in Mongolian. Located in the Qinghai Lake Basin in the northeast of Qinghai Province, it is not only the largest inland lake in China, but also the largest saline lake in China. It is 105 km long and 63 km wide, with a maximum depth of 38 meters. The lake has a catchment area of about 29661 square kilometers and an altitude of 3196 meters. It is nearly 450 square kilometers larger than Poyang Lake, the largest freshwater lake in China. The source of lake water mainly depends on surface runoff and lake precipitation. There are more than 40 rivers entering the lake, including Buha River, bagowulan River, and biantang River, among which Buha River is the largest.

Geology and geomorphology

From the perspective of Geology and geomorphology, Qinghai Lake is a fault depression lake formed by fault block collapse in Meso Cenozoic (about 40 million years ago), which is a large Intermountain basin in Qilian Mountains. According to research, Qinghai Lake was an outflow fresh water lake connected with the Yellow River hundreds of thousands of years ago. Later, due to the dry climate and the rise of surrounding mountains, the connection between Qinghai Lake and the Yellow River was cut off, and the salt content of the lake water that could not be discharged gradually increased, so it became such a closed inland salt lake. At the front of Buha River Delta on the West Bank of the lake is the famous National Bird Island Nature Reserve. Every spring and summer, more than 100000 Brown headed gulls, spotted headed geese, cormorants, fish gulls, red ducks, swans, black necked cranes and other birds gather here to incubate their eggs and brood. Many of them not only come from the south of China, but also from the south of China,
