1984 On New Year's Eve, a young man from the northeast quietly threw a New Year's card into the mailbox, and the address was: Beijing CCTV. Soon, this new year card was integrated into more than 5,000 letters from the audience. ...
A few months later, the song "Song of the Yangtze River" came out, and the name "Hu Hongwei" attracted worldwide attention. Hu Hongwei is a youth in Northeast China; He wrote the lyrics of "Yangtze River" on the New Year card.
A year ago, CCTV broadcasted a feature film "The Story of the Yangtze River" for half a year. At that time, every weekend night, thousands of families in Qian Qian finished their housework and homework early, then sat in front of the TV and waited for the familiar opening music to play. ...
The story of the Yangtze River is definitely the boiling point of 1983 China TV. With its playing effect, the opening music has become a familiar melody ... but gradually, people are not satisfied with just following the melody "la la la", hoping to fill in the lyrics and become a song. Therefore, the film crew adopted the suggestion, and on February 25th 1983, they sent out "Inspiration for Collecting Lyrics of Music Stories on the Theme of the Yangtze River" to the whole country. In just three months, more than 5,000 entries from all over the world poured in-Hu Hongwei's Song of the Yangtze River was the best one.
This song avoids the description of the Yangtze River water, but starts with people's true feelings about the Yangtze River and sings the first river in China from the heart.

The Yangtze River is the largest river in China. Originated in the southwest of Gladin Cave Snow Mountain, the main peak of Tanggula Mountain on the Qinghai-Tibet Plateau (33 28' north latitude and 9108' east longitude), the end of the source glacier is more than 5,400 meters above sea level. The main stream flows through Qinghai, Tibet, Sichuan, Yunnan, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Shanghai 10 provinces, municipalities and autonomous regions, and flows into the East China Sea east of Chongming Island. The tributaries also flow through eight provinces, including Gansu, Shaanxi, Guizhou, Henan, Zhejiang, Guangxi, Fujian and Guangdong. The main stream is more than 6,300 kilometers long, ranking third in the world. The drainage area is 6,543,800,000 square kilometers. Most of the river basins are located in the subtropical monsoon climate zone, which is warm and humid. The average annual precipitation is 1 100mm, and the average annual water inflow into the sea is nearly 1 trillion cubic meters, accounting for about 36% of the total river runoff in China. The water volume ranks third in the world, second only to the Amazon River and the Congo River, which is equivalent to 20 times of the Yellow River (see the world river comparison table).
The Yangtze River system is developed, with thousands of tributaries and 49 tributaries, with a drainage area of more than 654.38 million square kilometers, and four tributaries of Jialing River, Hanjiang River, Minjiang River and Yalong River, with a drainage area of more than 654.38 million square kilometers. The middle and lower reaches of the Yangtze River are the most concentrated areas of freshwater lakes in China, including Poyang Lake, Dongting Lake, Great Lake and Chaohu Lake.
The upper reaches of the main stream of the Yangtze River reach Yichang, Hubei Province, with a length of about 4,500 m kilometers and a drainage area of 6,543.8+0,000 square kilometers. Rivers pass through plateaus, mountains and basins, Jinsha River and Three Gorges to reach mountainous valleys, and the current is swift. The climate belongs to Qinghai-Tibet alpine region and subtropical monsoon region. The main tributaries are Yalong River, Minjiang River, Jialing River and Wujiang River.
Yichang-Hukou in Jiangxi is the middle reaches, with a total length of 938 kilometers and a drainage area of 680,000 square kilometers. Among them, the section from Zhicheng to Chenglingfan is called Jingjiang River, which twists and turns and is also known as the "nine-bend ileum". The main tributaries are Qingjiang River, Dongting "Four Waters" (Xiang, Du, Yuan and Li), Hanjiang River and Poyang "Five Waters" (Gan, Fu, Xin, Rao and Xiu).
From Hukou to the Yangtze River estuary, it is downstream, with a length of 835 kilometers and a drainage area of 6,543,800 square kilometers. Below Datong, Anhui Province, affected by tides, the water potential is gentle. Jiangyin, Jiangsu Province to the Yangtze River estuary, with a trumpet-shaped river width extending from 1200m to 9 1km. The main tributaries are Qingge River, Shuiyangjiang River, Chuhe River, Qinhuai River and Huangpu River. Most of the water in the Huaihe River also flows into the Yangtze River through the Beijing-Hangzhou Canal.
The plains and hills on both sides of the middle and lower reaches of the Yangtze River are low in altitude, and the cold and warm air is unimpeded from north to south. East Asian monsoon activity is very obvious, and the climate has four distinct seasons. Rivers are characterized by lotus root nodes, with a central beach and branches exposed in the open reach. There are more than 3 100 kilometers of trunk dikes on both sides of the middle and lower reaches of the Yangtze River. Tens of thousands of kilometers of people's dikes and seawalls have been built, and 40 flood storage areas have been built to alleviate the flood threat. By the end of 1992, 45,000 large, medium and small reservoirs had been built, with a total storage capacity of nearly14 billion cubic meters, which played a comprehensive role in flood control, power generation, irrigation and aquaculture.
The irrigated area of the Yangtze River Basin is 6.5438+0.467 million hectares, accounting for 63.3% of the cultivated land and 30% of the national irrigated area. The Yangtze River basin is rich in hydropower resources, with the exploitable amount reaching 65.438+0.97 billion kilowatts and the annual power generation reaching 654.38+0 trillion kWh, which is second only to Brazil in the world. The installed capacity of the completed Gezhouba Water Control Project is 2710.5 million kilowatts, and the installed capacity of the Three Gorges Water Control Project under construction will be10.82 million kilowatts, ranking first in the world. The Yangtze River Basin is an important economically developed area in China. By the end of 1992, the population was 398 million (accounting for 34% of the country), the cultivated land was 348 million mu (accounting for 24% of the country), the grain output was 654.38+55 million tons (accounting for 35% of the country), and the rice output accounted for 70% of the country. Cotton output accounts for more than 1/3 of the whole country, and agricultural output accounts for 32% of the whole country. Chengdu Plain, Jianghan Plain, Dongting Lake Area, Poyang Lake Area and Taihu Lake Area are important commodity grain bases in China.
There are 185 cities in the Yangtze River valley, and the big cities with non-agricultural population 1 10,000 or more include Shanghai, Nanjing, Wuhan, Chongqing, Chengdu, Kunming, Changsha, Hangzhou, Nanchang and Guiyang.
