Mystery of the source of the Yangtze River

The Bulletin on Water Resources in the Yangtze River Basin and the Report on Maintaining a Healthy Yangtze River issued by the Yangtze River Water Resources Commission show that the water quality of the Yangtze River is generally acceptable, but it has shown a deteriorating trend, so it is urgent to strengthen water quality protection.

The Yangtze River basin covers an area of about10.8 million square kilometers, involving Qinghai, Tibet, Yunnan, Sichuan, Chongqing, Guizhou, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Shanghai 12 provinces, autonomous regions and municipalities. According to the monitoring and evaluation of the 37,447 km river length in the Yangtze River Basin by the Yangtze River Hydrographic Bureau in 2004, the water quality of the Yangtze River is generally good, with the first, second and third types of water with good water accounting for 72.5% of the total river length, but the proportion of river length inferior to the third type of water has increased from 22.5% in the previous year to 27.5%, of which the fourth type of water is 26 1638, and the fifth type of river/kloc-. The length of rivers inferior to the fifth category is 5817km, accounting for 15.5%.

The annual net flow of the Yangtze River is about 960 billion cubic meters, accounting for 35% of China's total water resources, but its sewage discharge also accounts for 34% of China's total. In 2004, the total wastewater discharge was 28,865,438+tons (excluding 24,820 million tons of direct cooling water from thermal power plants and mine drainage), an increase of 65,438+48 million tons over the previous year, with a growth rate of 5.4%. Among them, domestic sewage exceeded 8 billion tons (including 2.53 billion tons of tertiary industry and construction industry), accounting for 29.6%, and industrial wastewater exceeded 20.2 billion tons, accounting for 7.04%. At the end of 1970s, the annual wastewater discharge in the Yangtze River Basin was only 9.5 billion tons, and at the end of 1980s, it was 654.38+0.5 billion tons.

The sediment volume of Tuotuo River has increased, which is caused by floods, and may also be caused by natural or man-made destruction of grasslands, but whether Tuotuo River has been destroyed or not is unknown. Due to the influence of global warming and other natural environment, the glaciers in the source area of the Yangtze River are shrinking year by year, especially the ancient glaciers tens of thousands of years ago are shrinking.

1979, China officially confirmed the Jianggendiru Glacier located in the upper reaches of Tuotuo River as the source of the Yangtze River, and released the photos of Jianggendiru Glacier taken by the photographer of the Yangtze River expedition team, such as Mr. Sui Chu, in 1976 to the world for the first time.

In June 2009, Mr. Qu Xiangdong and 28 members of the "Two-time Plan" film crew visited the source of the Three Rivers and successfully photographed the source of the Yellow River and the starry sea. The scattered lakes in the past have become today's Gobi wasteland. Subsequently, the investigation at the source of the Yangtze River became muddy due to the melting of ice and snow. After hundreds of traffic jams, the expedition had to stop at a distance of 0/8 km from Gangenderu Glacier/KLOC-.

March 2065438+00 12 Qu Xiangdong and 20 members of the "Two-degree Plan" team visited Jiangyuan again, and successfully photographed the appearance of Jianggendiru Glacier in the Jacky of the Yangtze River. Glacier shrinkage shocked the world!

On June 5438+February 18, 2009, the Copenhagen Climate Conference made this topic, which has existed for many years in some countries and certain professional fields, instantly become a global topic and a controversial topic. What is the truth about climate change? Is what you saw true? Is the hearing empty? How to interpret the attitude of China government? How will the resulting political and economic environment change? As a China person, is there any chance to stay out of it? How should we react and what should we do?

On March 3rd, 2065438, KLOC-0, Peking University Institute of Strategic Studies and Peking University MBA Alumni Association held a special press conference. The content of the conference is two photos: these two photos were taken in 2009 and 20 1 year respectively. The content of the picture is the source of the Yangtze River and Yellow River, the mother river of the Chinese nation: Xinghai and Jianggendiru Glacier. The photographers of the pictures are Qu Xiangdong, a famous host of CCTV, and Mr. Wang Hairong, the chairman of Singapore RH Energy Company, a teammate of his "Second Plan" scientific research team. They went to the plateau on 20 10 with the photos of the two places taken by famous photographers such as Mr. Sui Chu in the 1970s, and went to the Sanjiangyuan area to look for the location as taken by Mr. Sui Chu. Finally, on March 10 and 15, we successfully reached the Jianggendiru Glacier in the Jacky of the Yangtze River, and completed the purpose of investigation and shooting.

Judging from the pictures they released on the spot, after more than 30 years of vicissitudes, Xinghai at the source of the Yellow River has existed in name only. In the past, the beautiful lake scenery was dotted, and it was obvious that large glaciers retreated and melted.

After reading these two pictures, people can't help but think of the drought in southwest China. What's going on here? Is global warming the direct cause of these phenomena? Is human life and production the real culprit? Scholars and experts attending the meeting, Qu Xiangdong and Wang Hairong of the "Three Rivers Source Scientific Research Team of the Second Plan" have caused more in-depth discussions and even heated debates on these topics. Poachers used guns against anti-poaching law enforcers. Poachers hunt all kinds of precious animals and use mercury chloride. The use of mercury chloride means that the poaching tools used by poaching gangs have changed. Instead of poaching with easily exposed guns, they use anesthetics to kill rare animals, which brings more serious problems to the ecological protection of the Yangtze River.

The scientific research soldier deciphers the adventure: When the song becomes longer, is she the source of the Yangtze River?

Singing children's songs in the thrilling storm of scientific research

Liu Jian, who is both the team leader and the captain of the drifting boat, said that when the drifting team learned that the drifting boat could not go upstream, only 15 packets of instant noodles and a little dry food were left, the team members began to be humble to each other. Some said they didn't like instant noodles, others said they didn't want to eat them because of diarrhea, so they all gave their noodles to their teammates. They cooked the last three boxes of instant noodles for breakfast on the day of their escape. Motor caught a cold, and Feng Chun had loose bowels. Finally stood up, they still wouldn't let the other players recite: "We can walk by ourselves, save some energy!" "

During the three days when I lost contact with the big army, I encountered at least 1 rainstorm and hail every day. At this time, the players will push the power boat ashore and hide under the poncho to sing. "The Red Army is not afraid of expedition difficulties" is the opening song of each "concert", and then children's songs are sung until the rainstorm and hail stop before embarking on a drifting trip. As an old drifter of 1986, Wang Lishi said with emotion: "If you encounter irresistible factors, you must ensure the safety of the players. Twenty years ago, it was passion and adventure. After 20 years, it was more rational and thinking. " The "Reconnaissance Inspector Jiangyuan" expedition drifting team completed the exploration of the source of the Yangtze River in Qujiang, and the news of its return to Chengdu was reported by this newspaper, which attracted readers' attention. Yesterday, Liu Jian, Wang Martyr, Gao Ming and other team members were interviewed by our reporter and exclusively declassified the expedition.

This time, the first task of the expedition team is to measure the accurate data of the length and flow of the Dangqu, so as to prove with data who should be the source of the Yangtze River, Dangqu and Tuotuo. Liu Jian, the leader of the expedition team and the chief reporter of this newspaper, said that the expedition team completed a comprehensive inspection of Dangqu. However, the relevant data cannot be released immediately. Professor Tang Bangxing, the chief scientist of this activity, and other experts have to sort out and demonstrate it before it can be released and submitted to the relevant departments. Liu Jian said: "What can be announced at present is that Dangqu, like Tuotuo River, originated from glaciers, not swamps as previously thought, which shows that Dangqu is more likely to be the source of the Yangtze River."
