Where is the Kubuqi Desert?

Kubuqi Desert is located in the northern part of the ridge line of Ordos Plateau, and in some areas of Hanggin Banner, Dalat Banner and Zhungeer Banner in Ordos City, Inner Mongolia Autonomous Region.

Kubuqi Desert is the seventh largest desert in China. It is located in the south bank of the Yellow River (some people call it Hetao Desert) at the zigzag bend of the Yellow River in the Hetao Plain, and the Langshan area in the Shanxi section of Yinshan Mountain is in the north. "Kubuqi" is Mongolian, which means the string on the bow, because it is under the Yellow River like a string hanging on the Yellow River. In ancient times, it was called "Kujesha" and "Broken Shana", also known as "Punasha".

Kubuqi Desert is the nearest desert to Beijing. The total area is about 1.39 million square kilometers, and mobile sand dunes account for about 6 1%. They are 400 kilometers long and 50 kilometers wide, and the sand dunes are 10 ~ 60 meters high, like a yellow dragon lying across the three banners in Inner Mongolia in the northern part of Ordos Plateau. The landform is dominated by sand dune chains and lattice sand dunes.

On July 28th, 20 15, China's seventh largest desert 1\3 was awarded the 20 15 Land Life Award by the United Nations, and China's vigorous development of desert economic governance model gained the significance of world specimens. China Yili Resources Group and Egyptian SEKEM were awarded the 20 15 Land Life Award by the United Nations Convention to Combat Desertification tonight. Establish Kubuqi International Desert Forum.

I. Geographical environment

The eastern Kubuqi desert has good water conditions and belongs to semi-arid areas. There is little precipitation in the west and it has entered an arid area. The desert area has good light, heat and water conditions, which is suitable for the growth of food crops and cash crops. The eastern, central and western parts of the desert have their own characteristics, with more rainfall in the central and eastern parts and sufficient heat in the western part.

There are about 10 seasonal valley rivers in central and eastern China, which originate from the north side of the plateau ridge and flow longitudinally between them, with the characteristics of long valley, dry Xia Dong and high sediment concentration. There are often valley terraces with different areas on both sides of the gully flowing through the desert. The buried depth of groundwater is 1~3 meters, and the soil fertility is also high, with scattered oasis landscape, forming superior microclimate conditions.

There is little surface water and water resources in the west. Only the Shalimolin River disappeared in the northwest desert. The groundwater in the western end and northern part of the desert is affected by the Yellow River, with a buried depth of 1~3 meters, and the water quality is good, which is also within the scope of the Yellow River Diversion Irrigation Area.

Second, the terrain.

Kubuqi desert is flat, mostly floodplain and yellow river terrace, which is suitable for developing food crops and cash crops; Where the conditions in the central and western regions are poor, trees can be planted, sand sealed and grass planted, and small livestock can be developed. The northern part of the desert and the east and west ends are close to the Yellow River, and the conditions are superior. The height difference between the first terrace and the floodplain is very small, and the water level of the Yellow River in some areas is about 10 meter higher than the ground.

In the past 50 years, the region has built a 250-kilometer main canal of the South Yellow River, which is irrigated by the Yellow River and has become one of the key grain production bases in Inner Mongolia. Conditions in the eastern desert are very good. At present, it is necessary to prevent quicksand from invading south, expanding north and moving east. In the future, we should give priority to forests, combine trees, irrigation and grass, and give priority to irrigation. The combination of belt and net is mainly belt; Planting grass in the open space; In semi-fixed sandy land, we can use aerial seeding of pasture to reduce the flow range of sand dunes.

Animal husbandry production should focus on small livestock, strictly control the number of livestock, do a good job in natural grassland protection, rational utilization, key construction, and improve grassland yield and quality. Closing sand to facilitate afforestation, planting grass and improving vegetation coverage rate are the long-term development direction and construction ways of this area.

For areas with runoff on the northern slope of the southern margin, it is necessary to comprehensively and reasonably arrange water diversion into the sand, prevent and control sand, and ditch water diversion across the sand belt to enter the northern open plain. The following measures should be taken in the utilization of gully water resources: (1) Pay attention to the upstream soil and water conservation; Midstream interception and flood diversion; Downstream flood diversion irrigation.

Third, climate.

The climate type of Kubuqi Desert belongs to the arid and semi-arid area in the middle temperate zone, with high temperature, large temperature difference between day and night and dry climate, with 25-35 windy days every year. The eastern part belongs to semi-arid area, with relatively more rainfall; The west is an arid area with abundant heat.

There are more than ten seasonal gullies originating from the north side of the plateau ridge in the central and eastern parts, and the soil fertility along the coast is high; There is almost no surface water and water in the west, only the inland river Shalimolin River disappears into the desert in the northwest.
