In this area, it is difficult for cars to pass, and the means of transportation for the expedition are horses and yaks.

A horse is equivalent to a "passenger car" and a yak is a "wagon".

The dozens of yaks came from different families and were not familiar with each other, and under the arrangement of the township leaders, these yaks temporarily formed a transport team.

After being frightened, the yaks are wild, and they fight in groups with their families as combat units.

Click!

This is the sound of horns colliding with horns, resounding across the plateau.

Shen Qi, Xu Zhou and other scientists from the low-altitude areas of the capital had never seen the chaotic scene of the yak herd's chaos, and they were at a loss for a while.

Yaks are an irreplaceable means of transportation on the plateau, and if a few yaks are killed or injured due to fighting, it will cause irreparable huge losses to China's scientific research work.

At this critical moment, only a clear whistle was heard, and a rider came out.

The rider was a majestic man, wearing a felt hat on his head, a leather jacket, a shotgun on his shoulder, and a leather whip in his hand, dressed as a Tibetan hunter.

Smack!

The rider slammed the ground and whistled a few more rhythmic whistles.

"Ahh

One thing descends one thing.

After such a combo by the riders, the yaks were quiet, and the chaos was brought under control.

Shen Qi and Xu Zhou joined forces, and this scientific expedition team was mainly composed of personnel from Yan University, and the University also sent scientific expedition personnel from related specialties.

The Tibetan boy who bravely tamed the yak was called Ngawang, the caretaker of the Ngoling-Zhaling Lake Reserve and the guide of the expedition.

"Brother Awang, good skills. Shen Qi was full of praise for the Tibetan guide and asked for tips on taming yaks.

Ngawang taught Shen Qi the bullwhip method and related formulas, and Shen Qi memorized it in his heart.

The expedition team rode horses and cattle all the way west, and when it was late, they set up tents and rested overnight.

The joint scientific research team of Yan University and Earth University came with a mission, and scientists from various specialties talked around the bonfire at night, and the starry sky on the plateau was incomparably bright.

The group of scientists agree that global warming is exacerbating the drought and lack of water in northwest China.

The irrational intervention of human beings in the ecological environment is an important reason for the rapid deterioration of the environment in the Sanjiangyuan region in recent decades.

"Man-made disasters require the government to strengthen management. Natural disasters require the joint efforts of those of us who are scholars. "Shen Qi takes yak dung and puts it in the bonfire, and the best energy source here is yak dung.

"Yes, if we don't make up our minds to improve the ecological environment, humanity will be doomed. Xu Zhou wrapped his jacket tightly, it is the height of summer in July, but the night on the plateau is unusually cold.

Scientists from the capital talked about science, but Ngawang didn't understand the professional knowledge, so he patrolled with a shotgun and acted as both a guide and a bodyguard.

"Brother Ngawang, come and sit down. Shen Qi waved at Ngawang.

Ngawang walked to the campfire, looking a little restrained, and he was the least educated of the group.

"Brother Ngawang, you are most familiar with the plateau, tell us the story of this place. Shen Qi said.

"Digging for gold, digging up Cordyceps, digging us rich and poor. Ngawang spoke half-baked Chinese, telling the past of Sanjiangyuan in simple language, supplemented by a Han cadre in Maduo County.

Gold and Cordyceps are abundant in the Sanjiangyuan region, two precious resources that have not only brought wealth to the Sanjiangyuan region, but also caused great damage to the ecological environment here.

During the reign of Ma Bufang, large-scale gold mining began here.

Although the productivity at that time was extremely low, the gold that was put into Ma Bufang's private treasury was more than 40,000 taels every year.

Ma Bufang's gold mining troops had dug up a huge gold nugget weighing 23 kilograms in Maduo County, Ma Bufang was overjoyed, thinking that the sky was auspicious, and immediately ordered someone to make a very delicate large mirror frame and display the gold nuggets.

This gold nugget has a peculiar shape, like a fierce dog roaring in the sky, the bright golden light is dazzling, and everyone who sees it is amazed.

How much gold Ma Bufang took with him when he fled is still a mystery.

I heard that when Ma Bufang was in exile, he indirectly crushed the plane due to carrying too much gold, so he had to temporarily change his escape plan.

"Too much gold is dug up, it's not good, it destroys the environment, the water turns yellow, and there is a lot of sand. With his simple words, Ngawang expressed a strong desire to protect the environment of the source of the three rivers.

"Ma Bufang's period was basically destructive mining, and after so many years of mining, it can be seen that the gold reserves here are extremely amazing. However, the price we pay is also enormous. The Maduo County cadre shook his head and sighed.

Compared with gold digging, non-professional digging of Cordyceps causes deeper damage to the Sanjiangyuan area.

In the 90s, a large number of outsiders poured into Sanjiangyuan, they had no experience in identifying Cordyceps and digging Cordyceps, so they took the way of plowing the ground to find Cordyceps, often busy for several days, not a single Cordyceps was found, but the excellent grassland was turned over by them.

After digging up Cordyceps, the outsiders slapped their butts and left, and the local aborigines had nowhere to go, and all kinds of evil consequences were borne by local residents and cadres.

The vegetation in the headwaters of the Yellow River has been severely damaged, creating large areas of sandy land, which has also affected the middle and lower reaches. In recent years, landslides and debris flows have emerged one after another, and the state invests astronomical amounts of manpower, material and financial resources in emergency rescue and disaster relief every year.

So Ngawang stopped herding sheep, and he realized that only by protecting the environment in his hometown could they survive.

After dawn, the expedition team continued on its way.

Going deep into the Yellow River headwaters nature reserve, there are more and more wetland swamps.

In a small area, there are countless water pools and seas of different sizes and shapes, among which the large ones are several thousand square meters and the small ones are only a few square meters.

Shuibo and Haizi are like mirrors inlaid on jade-like jade plates in the summer sun, and they are connected together like peacocks, and the Tibetan compatriots in history called this section of the Yellow River the Peacock River.

"Fortunately, the ecological environment near the source remains in good condition. The expedition team stopped and collected scientific data on the climate, hydrology, geology and other aspects of the area.

Suddenly, a crisp cry sounded in the sky, and everyone looked up, all excited: "Look, black-necked crane!"

A flock of large birds hovering in the air, with white wings and black necks, is particularly beautiful.

When Ngawang saw this bird, he bowed his head and muttered this, reciting the scriptures.

The Tibetan people believe in Buddhism and are very fond of the black-necked crane, calling it "fairy crane", "sacred bird" and "auspicious bird".

The black-necked crane is a frequently endangered species, and the scientific expedition team can meet the wild black-necked crane here, which everyone thinks is a symbol of auspiciousness.

Shen Qi picked up the camera and clicked at the sky, and he brought a high-performance camera to take pictures of this group of wild black-necked cranes.

Just with the photos of these wild black-necked cranes, plus a simple text description, back to the capital to sort them out a little, you can form a zoological paper express.
