For me, the earliest cognition of the desert came from ancient poetry. The most famous of these was Wang Wei’s phrase “solitary smoke in the desert and the river flowing down to the Japanese yen.†The corresponding impression was rough and desolate. .
In recent years, more and more people have chosen to go hiking in the desert and experience different scenery in the desert, so the image of the desert in the mind gradually becomes clear and the image.
According to the reasons for formation, desert landforms are varied. The shape of the Yadan landform formed by wind erosion rills is peculiar, and the wind erosion lake formed by wind erosion and water accumulation can always surprise people. Looking around, there is only sand, or high or low sand dunes, the lizards crawling under the feet, the lake that suddenly appeared in the sky and the earth. This visual impact and spiritual pleasure have inexplicable appeal and satisfy curiosity. It is full of joy.
Deserts are mostly border areas. There are many traces of cultural exchanges and collisions. Some historical sites and diverse cultural and ethnic characteristics also have great charm. The crisp beard ringing sounds as if we are telling us about the magic of dust in the sand.
Is there only sand in the desert?
We all know that the desert is vast and boundless, but it is seldom realized that the desert accounts for nearly one-third of the earth's land area, and it is still expanding.
The desert is the land of sandy desertification. The surface is covered with sand. The living environment is poor, the vegetation and organisms are scarce, the high temperature is dry, and the precipitation is also low.
However, the desert is not only sand. Perhaps it is because the yellow sand in the desert is lost. So the creatures and oasis that appeared by chance appear to be precious. Animals in the desert mostly hide in caves during the day, avoid high temperatures, go out at night, and some animals and plants live mostly in oasis or semi-desert areas around the desert.
The deserts of our country are mainly distributed in the northwest, the northern part of North China and the western part of northeast, and there are eight deserts and four sands. The combined area exceeds one-tenth of the national land area.
Eight deserts: Taklamakan Desert, Gurbantonggut Desert, Badan Jaran Desert, Tengger Desert, Ulan Buh Desert, Kubuqi Desert, Desert in Qaidam Basin, and Kumutag Desert; four major sands Land: Horqin Sandy Land, Mu Us Sandy Land, Hunshandake Sandy Land, Hulun Buir Sandy Land.

Is it dangerous to walk in the desert?
As more and more people enter the desert, and the safety awareness of desert walking is also on the agenda, how dangerous is desert walking?
In the desert, one can't see the edge. When the wind rises, the traces that have passed will soon be buried in the sand. It will be difficult to find water and food supplies. It will also be subject to high temperatures, large temperature differences between day and night, etc. It will be dangerous just to think about it. .
However, compared to high-altitude mountain climbing and unmanned area trekking, it seems that there will be fewer accidents in desert walking. It is true that there are not many people walking through the desert. Most of them are experienced walking, but they are still not allowed to walk.
In May 2006, a female donkey friend from Beijing fell into a coma after crossing the Kubuqi Desert and died after being rescued. Unfortunately, she was killed.
In May 2015, two university students lost their lives when crossing the Badain Jaran Desert. On the 12th day of their journey, the rescue team found them and died.
Do not walk into the desert with gentleness.
Disorientation and lack of water are the greatest risks in the desert, which may lead to a series of problems such as excessive energy consumption, heat stroke, and hallucinations.
get lost
If it is a commercial team, then the team leader will lead the way, do not need to consider the line problem. If you play yourself, if you do not plan well in advance and navigation equipment is not in place, you are likely to get lost. The navigation device can be a GPS, a map compass, or even a line track downloaded by a mobile phone, but only if you have to use it.
If you are lost, you must calm down and stop to assess the current situation. Do not sit or lie on the ground. Because the sun will shine directly and the surface temperature will be higher, try to remember your last accurate position. Before deciding on the next step, It's best to stay in the same place waiting for help.
If you feel that you can find a way to go back, start immediately. Once you leave, you need to make a mark or leave a note at the starting point. If possible, it is best to find a place with high ground and observe it carefully.
When you need to be rescued, be sure to save your physical fitness as much as possible, and set a distress signal: You can take off the clothes with the brightest colors and hold them in high places. Of course, the most effective is the “daytime smoke, nighttime light†used in ancient times. Until you may not find other tools, then carry a daylight signal mirror, the glass has a long light emitting distance, and it is more eye-catching.
Water shortage
Water shortage is a taboo in the desert, and it is very dangerous to cause dehydration at high temperatures. To solve this problem, we can consider two aspects. One is reasonable water supply, and the other is how to eliminate water. Find water under.
Reduce sweating, wear clothing and hats, which helps to slow down sweat evaporation and keep your pace. When you drink water, keep in mind the principle of “a small number of timesâ€. First, solve the problem that the body is not short of water and then talk about the need to quench your thirst. In the evening, after the camp, boil the small cup of tea slowly and drink until the urine is in full. In this case, the body's moisture will not be lost.
Of course, can not drink too much water, can easily lead to hyponatremia, that is, water intoxication, so when a lot of water and no urine when the quote must tell the partner around.
How to find water in the desert depends on the desert. The desert terrain in the country is affected by the surrounding address environment. The groundwater level is different. Take Tengger Desert as an example, the groundwater level is high, and there are more than 400 lakes. There are also more than 100 water sources, and groundwater is commonly found in water sources.
No matter how you find the source of the water, keep in mind that drinking must be preceded by clarification and filtration before you can refer to it, otherwise it is easy to drink parasites and cause other problems. Boiling and disinfection with iodine tablets are the most commonly used methods, and there are also instruments for purifying water.
Following the trajectories of plants and animals is also a good way to find water sources, Figure / wikihow
Heat loss
Walking at high temperatures for a long time can easily cause sunburn, heat shock, or even heat stroke. The main symptoms of general sunburn are skin redness and pain, severe swelling, blisters, and even fever and headaches. Heat shock can lead to excessive sweating, trembling, and even vomiting and fainting. It requires cooling and electrolyte supplements. Heat stroke should be regarded as a serious disease. Drugs should be taken as soon as possible and cool down. Otherwise, there is a risk of fatality. .
The heatstroke in the desert may be well understood. Many people will also be fully prepared. However, in the desert, the people considered will be much less. When it was clear in 2016, the Tengger Desert suffered heavy snowfall. Many people lost temperature due to insufficient preparation.
The temperature difference between day and night in the desert itself is large, especially in winter, the possibility of loss of temperature is higher, therefore, must be optimistic about the weather before departure, make adequate preparations, and develop habits with rescue blankets.
Will desert sandstorms be encountered in the desert?
I believe that friends living in the North are not unfamiliar with sandstorms. What would the sandstorms in the desert look like? In simple terms, dust storms in the desert are divided into four levels: "dust, dust, dust storms, and black storms." When the worst black storm occurs, there is only 3 or 5 meters of visibility in the daytime.
The probability of sandstorms is very low, and mainly dust, basically will not affect normal walking. What needs to be done is to wear windbreakers, masks, headscarves and other sand prevention measures.
When there are dust storms, the general temperature will also decrease. If sandstorms are encountered in the process of traveling, business clubs generally gather logistics vehicles together on the side of the incoming wind. The backpacks are hidden under the chassis of the vehicle, and people hide behind the vehicle. If you catch up in the camp, reinforce the tent and put all your personal belongings in the tent and sit inside until the dust storm subsides.
In addition, long-distance trekking in the desert may have the possibility of physical exhaustion, hallucinations, or even biting by poisonous insects at night.
Accurately and objectively assess your physical fitness when you travel and choose the route that matches it.
Desert Hiking Tips

Since it is on foot, some common techniques are also suitable in the desert, such as adjusting the rhythm and breathing, adjusting the backpack carrying system, timely replenishment of water, energy and electrolytes, pay attention to rest.
Of course, the desert as a special terrain has special requirements for skills.
Clothing: Do a good job of sun protection, wind protection, sand treatment. Wear high state hiking shoes, penetrate the air-drying long sleeves, wear sunglasses (goggles), masks, and reduce the skin's exposure. Wear a hat to protect the head and a scarf to protect the neck.
Line: Choose to walk on the windward side near the upper part of Shaliang. Wind is an important factor in shaping the desert's landforms. The deserts in the northwest region are popular with northwest winds, and sand dunes generally form a southeast trend.
The northwest side of the dune is facing the wind, with a small slope and hard sand. It will be much easier to walk. The bunker on the lee side is relatively soft and it is more troublesome to walk. When encountering obstacles, you should choose to walk around rather than over. When you encounter a steep slope, do not go straight up or down. Take the word line to prevent over-consumption of energy and try to walk along canyons and ditches.
Travel: Bring trekking poles and snow trays to reduce the impact on the sand surface, reduce the burden on the knees, and increase the efficiency of travel. Avoid activities during the hottest hours of the day (10 am to 4 pm).
Keep dry: try to make yourself less sweaty, take off your shoes and socks in the shade, and keep your feet dry.
Desert hiking equipment precautions:
1. Footwear uppers require full leather mesh, with sand cover (cross-country running sand cover);
2. For the purpose of sun protection, the fisherman's hat or devil cap with quick-drying and sweating is of vital importance.
3. Check the "five items": shelters (tents, rescue blankets), water, fire (magnesium sticks or flints), signals (whistle or a mirror) and first-aid kits;
4, flashlights, gloves and other hiking equipment.
