Where is the smallest desert in China?

As of March 20 18, the smallest desert in China is Mo Tian, with an area of only 200 mu.

"Mo Tian" is located in Longbaoshan, southwest of Xiaonan Xinbao Town, Huailai County, 90 kilometers away from Beijing. It is connected with Badaling Great Wall and Kangxi Grassland, and consists of mountains, Gobi, deserts and lakes. It is the nearest desert to Beijing, with an area of only 200 mu. It is the smallest desert in the world, so it is also called pocket desert. The scenery in Mo Tian is very strange. Here, you will see a golden sand dune, which stretches for dozens of miles. Mountains, deserts, next doors, lakes and other natural landscapes form a unique landscape.

Every year in the windy season, Beijing suffers from severe sandstorms. To this end, the government dispatched armed police to plant trees near Mo Tian, and built an 8-kilometer-long, 20,000-mu windbreak and sand-fixing forest belt. So far, the ecological environment in Mo Tian has been significantly improved, and more and more tourists come to visit.

Tianmu Mountain is not only charming in natural scenery, but also has many interesting activities. To visit here, you only need to spend 20 yuan to enjoy a series of tours such as sand skiing and sand throwing. If you want to ride a camel, you can ride it for an hour at a cost of 100 yuan. If you are going to road trip, you only need to spend 30 yuan money to drive around the desert. When you are tired of playing, you can also eat local food, such as fresh river water from local reservoirs and pure local products. In addition, there are stewed pig's feet, stewed tofu, stewed carp in vinegar, fried shrimp and so on.

A typical feature of the sky desert is "well-defined". Around the desert in the sky, there is a clearly identifiable contour line. Even if you leave this contour line, it will be ordinary farmland immediately. In addition, in the east of Mo Tian, some sand has been transported away, and there is a clear dividing line between the bare ground and the accumulated sand. The ground is composed of purple-black coarse gravel, which is quite different from the accumulated sand in Mo Tian. This shows that the sand in the desert is not piled up from the ground and is not integrated with the land below. There is no sand source within hundreds of kilometers around Mo Tian, and there are many versions of its causes, such as electromagnetic cause theory, wind-blown sand formation theory, weathering cause theory and in-situ sand blowing theory. About the formation of sandstorm, there is a saying that it is formed by the strong northwest airflow carrying dust from Inner Mongolia Plateau and being blocked by Du Jun. However, the exact cause is not conclusive, and the cause of desert is still a mystery.
