Located at the head of the front set of the Yellow River, Xiangshan in the south, Tengger Desert in the north, and alluvial plain in the middle of the Yellow River, the land area is 4599.3 km, which is one of the 20 key desert control areas in China.

Geology and geomorphology

The terrain of the reserve is high in the northwest and low in the southeast, inclining from the northwest to the southeast. Sand dunes are vertical and horizontal, with ups and downs. They cover the red sandstone, flood terrace and alluvial plain of the Second or Tertiary. The desert in the protected area is formed by the forward accumulation of the Tengger desert. The thickness of the sand layer is generally 20-30 m, and the thickest is up to 50 m. Most of them are ridge dunes, crescent dune chains, crescent dunes and lattice crescent dunes, which constitute typical aeolian landforms.

climate

The Nature Reserve belongs to the temperate continental climate, and belongs to the temperate arid climate zone in the National Natural regionalization. It has the characteristics of drought, less rain, strong evaporation, large temperature difference between cold and hot, abundant light, strong wind and sand, long winter, short summer heat, late spring and warm, early autumn and more meteorological disasters. The annual average solar radiation is 6.2 *10J/m, the sunshine hours are 2776.72 hours, and the annual average temperature is 9.6 C. The lowest temperature in January is -25.1 C. The highest temperature in July was 38.1 C, with an annual difference of 63.2 C, accumulated temperature of 3017 C (> 10 C), and frost-free period of 179 days (> 0 C). The annual average precipitation is 186.6 mm and the annual evaporation is 3000 mm. It is 16 times the annual average precipitation, 2.4 degree of dryness, more than 900 hours of wind-blown sand, 2.8 m/s average annual wind speed, sand days in March to June, the maximum wind power can reach grade 8. Strong winds are often accompanied by sandstorms, with an average of 5 to 19 days a year. The wind direction is mostly northwest. The main disastrous weather is drought, frost, gale, rainstorm, hail, hot and dry wind, cold damage and so on.

hydrology

The surface water in the reserve mainly includes the transit water of the Yellow River, the meteorological runoff and the spring lakes. The runoff of the Yellow River varies greatly during the flood season and the dry season. The natural ratio of water surface decreases to about 1/1300, the flow velocity in the flood season is 2.2-4.0m/s, the normal season is 1.7-3.0m/s, and the dry season is 0.77-2.0m/s. The average water depth is 1.8-8.7 m in flood period, 1.7-5.2 m in normal period and 1.6-3.7 m in dry period. The average flow rate is 1038 m/s. Controlled by the base structure, some closed inland lake basins were formed. Inland lakes, such as alkali lake, small lake, Gaodun lake, Machang lake and barren grass lake, have a total area of 721 hectares. They are habitats of various vertebrate fauna in the region.

soil

The soil types in Shapotou Nature Reserve are relatively complex, with six soil types distributed. The total area of soil is 13262.6 hectares, mainly sandy soil. In addition, there are lime-calcareous soil, tidal soil, newly accumulated soil, irrigated and silted soil and saline soil. The area of aeolian sandy soil is 10 610 hectares, accounting for about 80% of the total soil area of the reserve; the area of lime-calcareous soil is 1127 hectares, accounting for 8.5% of the total soil area of the reserve; the area of tidal soil is 1 326 hectares, accounting for 10% of the total soil area of the reserve; and the total area of newly accumulated soil, irrigation-silt soil and saline soil is only 199.6 hectares, accounting for 1.5%
