[World Control and treatment desertification and drought day] Lu Qi: Primitive desert is the beauty of natural gifts

June 17, 2022 is the 28th World Prevention and Drought Day. The theme of our country is to "work together to prevent desertification and build a community of destiny."

Lu Qi:

Researcher at the Institute of Desertification of the Chinese Academy of Forestry

Desert is a valuable gift for nature to see research, not governance. What needs to be governed is desertification

Brothers who are side by side for ten years

I am glad to have the opportunity to share with you some of our experience and feelings in the desert science examination in the past decade, those day and night in the Kumtag Desert.

This is some of the members who have chosen some of the players we have participated in the ten -year scientific research. In fact, we have done this desert for ten years. Our team members have exceeded two hundred. We have gone through ten. There are more than 300,000 distances of tens of thousands of kilometers. There are more than 360 days we accumulated, so my longest time record is to stay in it for 14 days. My story today was told in 2007 ten years ago.

Kumtag's reputation rises

My current unit is called the Institute of Desertification of the Chinese Academy of Forestry, and our team is from all over the country. First of all, I would like to thank the Ministry of Science and Technology, the national science and technology basic work of this project, and support our perseverance. In addition, I also thank my team and comrades, I am the captain of the first issue.

Where is Kumtag? Let me take a look at it first: Kumtag came from the famous door, the east side was Dunhuang, and the west fingers were Lop Nur. Lop Nur is too famous, the south is Alkin, and the north is the arid Gobi. These four are more famous than it. But since 2007 we stepped into this deserted area and traveled through this hot land, this one has since become famous. Let's look at its full picture. The big ears on the left are Lop Nur, the oasis on the right are Dunhuang, our world -renowned city. The gray part of the south is Alkin, which is the full picture of Kumtag, the small picture in the lower right corner, and the small piece displayed in the middle is where Kumtag is located.

Kumtagi's natural scenery

When Kumtagi said that the desert, the eyes were full of yellow sand. Some of the small maps I showed here were some beautiful scenery in the area of ​​Kumtag. In the future, I have the opportunity to take everyone to enjoy it.

This is the Alkina on the south. Finally, I saw the white snow. It was the snowy mountains of the Alkina. The highest place was more than 4,500 meters.

This is the flood fan in front of the Alkina. When the flood comes, there is a place that is flat, mixed with a large amount of stone grains. This is an exit when the Alfen Mountain flood broke out. We called Karatasha. It means Blackstone Mountain, this is a Victoria. This is the mountain mouth of the vertical fan.

This is the deepest canyon encountered by our Kumtag Desert, and we are named Kumtag Grand Canyon. The depth of more than 120 meters.

The most famous here. The ancient book is called Mo He Yanzhang. In fact, now the map is called Gushun Gobi, and we can see that the mirage like the ocean. This was the 800 -mile dry sea that was passing by Xuanzang Western Regions at that time.

This is the hardest salt shell of Lop Nur. We describe the sharp sword like a stone. Don't wear ordinary leather shoes. We'd better put on the one that can't be kicked, and then we can pass it there.

This is the feather -shaped sand dunes we were looking for. We walked into this desert for this sand dunes. To show you, this is our drone aircraft.

This was as soon as I entered that year, I gave us a horse, and encountered sandstorms. Of course, we came back well.

Ten Years Examination Road

In the past ten years, all these yellow routes are the footprints under us. We use this GPS to point it down and upload it to the map, which basically traveled all aspects and corners of all deserts.

What are the weapons for scientific research, of course, there are also powerful and not powerful, the simplest two hands, this bare -handed therapy, we call the pits and soil with bare hands, the simplest is iron pupae, the highest major radar, grounding ground, grounding ground, grounding ground, grounding ground, grounding ground, grounding ground, grounding ground, grounding ground, grounding ground, grounding ground, grounding ground. Radar, infrared cameras, and large excavators, we all drove in.

New interpretation of "feather -like sand dunes"

Now I will introduce the three things we have discovered: the first is the latest interpretation of "feather -like sand dunes". In the past, our older desert scientists found that this area was only a feather -like sand dunes in this area, which was displayed in the lower right corner. This photo looked like a bird's last feather. In the past ten years, we have given it three interpretations: the first is like the large film in the lower left corner. The fan is the same. The picture on the right is the image of the feather -shaped dunes taken in the air in the air.

We say that the sand dunes should have a high -end part, that is, the part of the high and low part is called the hill. There are sand dunes accumulated in the sand. After we go in, we find that there is actually no hill. This is our most doubtful part. In the picture below, you can also see this ups and downs. In fact, after the scene, the measurement is very small, because the off -road vehicles we drive to 120 kilometers inside without bumps. Therefore, there are three interpretations of the feather dunes now. In fact, this is still uncertain. This is the first form.

How to form the second one? Our preliminary judgment is that the new moon -shaped sand dunes of the past are connected in series. That is, every sand dunes are hand -held, and finally it is seen on the film below.

The feather -shaped sand dunes we saw found that it was connected in parallel. Each crescent dunes were stringed in parallel. On the schematic diagram on the left, I signaled that a corner was blown by a strong wind. Connect together, and finally strings together to become a feather dune chain. These are the two evidences we currently get.

The first inference is formed by the floating landform. There is a floating landform first. Like the picture on the right, there is a gravel pile in it into a fish scale, and then the flowing sand is covered. Landform said.

Another kind of image we caught in an instant. Let's take a look. The photo on the right is a photo taken in the wild one day that day. Our imagination was that the wind stopped in an instant, and it was like a photo on the left, and the left was an empirical evidence. This is our style of style. But the wind blows and can't find it anymore, so this is the most doubtful place we are, and it is also the most meaningful part of science.

First of all, the "gravel" landform that is found and named

Second, we found an important thing, that is, in the past natural geography textbooks, there was no record of a landform. We first discovered and named it gravel.

Why do we say that it is a unique geomorphic form, because we have never seen it in the past. There are few such forms in the desert. Either all gravel covers is called Gobi or all the flowing sand covers the desert. In the desert of the quicksand, it is found that a gravel covers is found, and it is a stacked object of a mixture, so we are named the gravel.

Everyone sees this black one, and there are other colors with very dark ones, but its form has various forms. There are this hill -like, tapered, and pile. It can be seen that this is a embankment. We initially infer that it should be piled up by the floods and the glaciers of the past ancient times. Those small pictures below can see that there are still circles, and how it was formed in the young age. This is our second accident on this regional landform.

Everyone inferred that the rock will crack after the weathering. Everyone was holding the rocks and thought of cracking. After you arrive at the Kumtag Desert, you find that the ground is full of cracking rocks. We call it weather. After the weathering, it was pressed to the desert, the wind blows, the sand can't go, and the surrounding area collapses automatically, forming a parallel process.

Another kind, you can see that I made a small image in the middle and show it to everyone. In the future, it will also change from one stone to two pieces, two pieces to four pieces, and four pieces of eight pieces. It will crack. After the cracking, it covers a small area, and then cover the sand. This is speculation. And assumptions, I hope friends who are aspiring will continue to explore.

This shows how the stone becomes sand, the bottom photo, this is the closer to Gobi, the right side, the front and back have become quicksand, that is, weathered little by little.

Gorgeous Yadan landform

Third, this area just saw the brightest name of Yadan, and Yadan was the abbreviation of Yaldan in Uyghur.

We see that the picture on the left is Yadan, which has just formed. On the right is middle -aged, basically like mine, and then we take a look at the old age.

Older people are now available for ordinary tourists, named Yadan World Geopark. We see this thousand ships, like warships, Wan Ship Qi Qi this is the most classic.

The diverse presentation of Kumtagri water

The least in the desert is water, but fortunately, this time, in the Kumtag Desert, we found a variety of forms of water.

Damper lake

Let's take a look at the dammed lake. The 5.12 Wenchuan earthquake in 2008 shocked a dammed lake in Kumtage. After two years of persistence, when we went again in 2010, the dammed lake was gone, so if you are not afraid that you can’t find it, you will not find it, so you will not find it. I was afraid that you couldn't catch it, and it was very coincidentally. We encountered the best time.

Tail lake

This is Tailing Lake. The most common, the rivers in the desert generally penetrated when passing through the desert, and the last thing that stayed was a small lake. It is seasonal, and sometimes there is no, and when we go, there are two lakes with water. There are spring water and floods in the desert

This is the spring water under Alkina. With the spring water, there is life. This is the La Fuquan spring.

This is the flood, which is the most difficult to see. One of the shortest and widest floods was taken in 2009.

Waterfall, Sand Waterfall in Kumtagri

This is a waterfall.

Why is it a water waterfall? Everyone thinks that there must be another waterfall, that is, sand waterfalls. This is more than 30 meters high, and the wind is like water. It is also a spectacular scene.

Kumtagri's vitality

With water, the desert has life and plants with life, which is a necessary primary productive forces. Then there is an animal,

The most classic of animals, the most cherished national first -level protection animals, wild twin peak wild camels. This is the other wild animals we took with infrared cameras. The middle is the Tibetan wild donkey, living in the Qinghai -Tibet Plateau, but we are fortunate to take the Tibetan wild donkey in this area.

This is another more precious snow leopard. We only took one in ten years, but at least it proved that it visited us in this place, so a very precious photo.

This is the Shuangfeng wild camel. This is the normal population we have taken. The largest population we currently get is 80 peaks, which is a large row. Because those photos are unclear, they did not show you. This is a very interesting thing. The camel on the left is a social animal, which is very disciplined. This is a scene we took when we took the camel in line to drink water. We moved it for it. On the right is a peak we took, that is, the white -lip wild camel. We wanted to make a species of identification. Unfortunately, I did not catch it, but I just took a image. Is it a variant or a new species.

Proposal establishment of "Kumtag National Park"

This hot land has a beautiful scenery, a charming animal, and a precious plant, so do we want to protect it?

We can see that we have proposed this one, and I can see that I have made it highlighting it. This is about 240,000 square kilometers, which involves three provinces and regions, Xinjiang Gansu and Qinghai. The largest in the ten national parks can be ranked third in this area around the world. This one is also the most abundant landscape.

Are you ready? Let's walk into Kumtag together

In a national park, you can see the towering snow mountains, the Gobi, the lake, the desert, and the oasis.

Students or colleagues who want to see, prepare in advance, I will introduce to you how to prepare and prepare, so I will sign up. For seven days, do not brush your teeth or wash your face at home. Do not sleep on the bed. You can practice or eat instant noodles. You can also eat some food of the Marine Corps. They are all self -heating, that is, there is no tool for cooking. After seven days of practice, you still live well and ask me to sign up. We will have an appointment together next year. In May next year, we will go to Kumtag together and enter the desert. With your company, we sing all the way. Camtag saw.
