The sixth grade text "A willow tree in Qinghai Plateau"

A willow tree on the Qinghai Plateau is the text of Unit 5 in the first volume of Grade 6. This is a warm introduction to a stout willow tree growing on the Qinghai Plateau. Although this willow is an extremely ordinary willow, it is also a formidable willow with tenacious spirit and magical power, telling people not to complain about their fate when facing the hardships of life, but to fight against the living environment with tenacious perseverance and tenacity. Firstly, this paper points out the magic of a willow tree with two natural segments on Qinghai Plateau. Secondly, from the harsh growth environment of Qinghai Plateau and the towering support of this willow tree, it shows its strong vitality. Then guess and imagine the survival and robust growth process of the willow tree, which further embodies the tenacious perseverance of a willow tree in Qinghai Plateau. Then, I wrote about the easy growth of a willow tree in Bahe, my hometown, which shows that a willow tree in Qinghai Plateau dares to fight against its fate. Finally, it is pointed out in shocking words that this willow tree did not complain about its fate, but survived with unimaginable perseverance and tenacity, thus revealing the philosophy of life. Qinghai Province, referred to as Qinghai for short, is located in the northern part of Qinghai-Tibet Plateau in China. The province covers an area of more than 720,000 square kilometers with a population of 565,438+800,000. Xining, the provincial capital.

Qinghai and Tibet live together on the Qinghai-Tibet Plateau. The main mountain ranges are Kunlun Mountain, Tanggula Mountain and Altun Mountain. There are many basins in the mountains. The source of the Yangtze River and Yellow River dries up in this province, with Qinghai Tide, the largest lake in China. The province belongs to a typical continental plateau climate, with abundant sunshine, cool Leng Xia in winter and little rain.

The province's industries include mining, chemical industry, electric power, leather, wool spinning and other departments. Animal husbandry mainly focuses on raising sheep, yaks and horses. Agricultural production of wheat, highland barley, etc. The fishery scale of Chaohe Lake and Zhaling Lake in Qinghai is small.

Qinghai is a multi-ethnic province with Tibetan, Hui and Mongolian nationalities. The whole plateau is vast and the rivers are winding. Ethnic customs and plateau scenery make Qinghai tourism promising.

Qinghai Lake is connected with the sky, and the scenery is magnificent. Bird Island in the lake is an important habitat and transit point for migratory birds. The grassland along the lake is vast and the ethnic customs are colorful.

Xining, the provincial capital, is a plateau city with beautiful scenery. The green hills around the city are undulating, and the Huangshui River in the city is like a belt. Several mosques are the main attractions in the city, and Zhengri Mountain is where Princess Wencheng of the Tang Dynasty entered Tibet. It is bounded by Ri Ri Mountain, with agricultural areas in the east and pastoral areas in the west. The Ta 'er Temple in the southwest of Xining is extremely large. Butter carving, pile embroidery and mural painting are called "three wonders".

Golmud is the second largest city in Qinghai and an important transportation hub on the Qinghai-Tibet line. The spectacular "Zhang Wan Salt Bridge" in the suburbs is unique in the world.

There are many ice peaks and snow-capped mountains in the hinterland of Qinghai Province, which originated from the Yangtze River and the Yellow River that nurtured Chinese civilization. The natural ecology of the source areas of rivers and lakes has high scientific research value. However, in recent years, the environment in this area has been affected by human beings, which has a deteriorating trend and urgently needs attention and protection.

Tibetan knives, carpets and Cordyceps sinensis are the main local products. Xining and Golmud are the main transportation hubs.

He has been a teacher of Jiangcun Primary School of Maoxi Commune in Anjiao, a teacher and secretary of the League branch of Maoxi Commune Agricultural Middle School, a deputy director of the Commune Revolutionary Committee and deputy secretary of the Party Committee, a deputy director of Anjiao Cultural Center, a deputy director of the Municipal Baqiao District Cultural Bureau, a deputy director of Tongcheng Cultural Center, a vice chairman and chairman of Shaanxi Writers Association, a professional writer, and a first-class literary creation. Representative of the 13th and 14th National Congress of the Communist Party of China, alternate member of the 7th and 8th Shaanxi Provincial Committee of the Communist Party of China, fifth member of the Chinese Writers Association, vice chairman of the Chinese Writers Association, honorary director of academic committee of xi Youshi University, and director of China Modern Literature Research Center of Xi Youshi University. It can be explained that most of the Qinghai-Tibet Plateau is in Qinghai and Tibet, which is a whole, just like the Yunnan-Guizhou Plateau.

There is no such thing as Qinghai Plateau in China's geography, but only a part of it talks about the lack of geographical knowledge in the west, so it has two meanings, one refers to the Qinghai-Tibet Plateau, and the other refers to a part of the Qinghai-Tibet Plateau.

Qinghai-Tibet Plateau is the largest plateau in China and the highest plateau in the world, so it is called "the roof of the world".

Formation of Qinghai-Tibet Plateau

The geological history of the Qinghai-Tibet Plateau with definite evidence can be traced back to the Ordovician period 400-500 million years ago. Since then, there have been different data of crustal rise and fall in different parts of the Qinghai-Tibet region, either submerged by seawater or on land. By 280 million years ago (early Permian in geological age), the Qinghai-Tibet Plateau was now a rough Wang Yang. This sea area spans the southern part of Eurasia and communicates with the waters of North Africa, South Europe, West Asia and Southeast Asia. It is called "Tethys Sea" or "Ancient Mediterranean". At that time, the Tethys Sea had a warm climate, which made it a prosperous area for marine animals and plants. Its north and south sides are divided primitive ancient land (also called Pangu land), and its south side is called Gondwana land, including South America, Africa, Australia, Antarctica and the South subcontinent. The northern continent is called Eurasia, also known as Lauea, including Europe, Asia and North America.

240 million years ago, due to plate movement, the separated Indian plate moved northward and squeezed at a relatively fast speed, and strong folds, faults and uplifts appeared in the north, which promoted the Kunlun Mountain and Hoh Xil area to grow into land. As the Indian plate continues to insert northward under the ancient ocean crust, it pushes the ocean crust to break continuously. About 265.438 billion years ago, the North Tethys Sea once again entered the tectonic active period, the North Qiangtang area and the Karakorum area. By 80 million years ago, the Indian plate continued to drift northward, causing strong tectonic movement again. The Gangdise Mountains and Nyainqentanglha Mountains have risen sharply, and parts of northern and southern Tibet have also left the sea and become land. The whole terrain is broad and gentle, with rivers and lakes, vast plains, humid climate and lush jungle. The landscape pattern of the plateau has basically taken shape. Geologically, this tectonic movement of plateau uplift is called Himalayan movement. The uplift process of the Qinghai-Tibet Plateau is not a uniform movement, not a one-time skyrocketing, but has gone through several different stages. Every uplift makes the plateau landform evolve. Ten thousand years ago, the plateau rose faster, with an average annual increase of 7 cm, becoming the "roof of the world" on the earth today.

geography

There are many mountains around the Qinghai-Tibet Plateau, most of which extend from northwest to southeast. Compared with the ground outside the plateau, they suddenly rise, much higher. Among them, many peaks in the southern Himalayas rank among the top ten in the world, especially Mount Everest, which is the highest peak in the world. At the same time, there are many peaks in the plateau besides the plain, and the heights vary greatly. There are many glaciers, alpine lakes and alpine swamps on the plateau. The source of many major rivers in Asia is here.

Glaciers in the middle and low latitudes of the earth are mainly concentrated on the plateau. The glacier area in the Qinghai-Tibet Plateau is about 47,000 square kilometers, accounting for more than 80% of the total glacier area in China.
