The evaporation capacity is large, and the annual evaporation capacity is 2000mm-3000mm.
Ordos City is located in the southwest of Inner Mongolia Autonomous Region and the hinterland of Ordos Plateau. It borders Shanxi, Shaanxi and Ningxia in the east, south and west, and faces Baotou, the grassland steel city, and Hohhot, the capital of the autonomous region, across the river in the north and northeast. It is about 400 kilometers long from east to west and 340 kilometers wide from north to south, with a total area of 86,752 square kilometers.
Ordos' natural geographical environment is characterized by undulating terrain, high northwest and low southeast, and complex terrain. The northeast and west are surrounded by the Yellow River, and the south is connected with the Loess Plateau. There are all kinds of landforms here, from beautiful grasslands to open undulating plateaus. There are five types of landforms in the city. The plain accounts for 4.33% of the total land area, the hills account for 18.9 1%, the undulating plateau accounts for 28.8 1%, the Mu Us sandy land accounts for 28.78%, and the Kubuqi desert accounts for 19.
Northern Yellow River alluvial plain area
The total area of this area is about 5,000 square kilometers, accounting for 6% of the city's total land area. It is distributed in Hangjinqi, Dalat, Zhungeer Banner, 23 towns along the Yellow River and Sumu. The genesis and geological structure are the same as the whole Hetao plain, belonging to a long and narrow subsidence graben basin. Modern landforms are mainly formed by flood and sediment deposition in the sediment belt carried by the Yellow River. ? Altitude 1000- 1 100 meters, flat terrain and superior hydrothermal conditions. The soil types in this area can be divided into meadow soil, meadow soil and meadow soil. There are four types: swamp soil, saline-alkali soil and aeolian sand soil, among which meadow soil is the main one. Meadow soil is the soil with good texture and high productivity in this area. It is the basic soil for cultivating stable and high-yield farmland. In the whole alluvial plain of the Yellow River, the soil organic matter content is about 65438 0%, the total nitrogen content is 0.05%, the available phosphorus content is 65438±02 PPM, and the available potassium content is 228 PPM. At present, the area of cultivated land in this area has reached 6.5438+0.3 million mu, including 800,000 mu of irrigation area, and the grain output of 6.5438+0.989 years has reached 200 million Jin. The development prospect of this area is quite optimistic and has great potential. First, there are still 6.5438+0 million mu of cultivated land in this area. Dalat Banner alone has 750,000 mu of arable land for development. Second, the development project is simple and low-cost, as long as wells can be drilled and power can be supplied. Do a good job in field management, and the investment per mu is less than 100 yuan. At that time, it was fertile land, and the grain yield per mu was 200-250 kg; Third, the water source conditions are good, whether it is yellow irrigation or well irrigation, there is sufficient water source protection; Fourth, on the basis of water and fertilizer security, applying and popularizing advanced and applicable science and technology can increase grain production by 30%-50%; Fifth, local people have the experience and energy to develop land and improve production conditions; Sixth, relying on the conditions provided by agriculture, we can fully develop various economies such as pig, cattle, sheep and other aquaculture and processing industries. At present, the local people and the masses lack financial resources, and the development work cannot be carried out quickly. We warmly welcome all individuals and groups interested in planting to invest in land development and develop food production here. Carry out diversified operations.
Eastern hilly and gully region
This area is located in the south of Ejinhoro Banner, Zhungeer Banner and Dalat Banner in Ordos City, with an altitude of 1300- 1500m and an area of about 26,000 square kilometers, accounting for the total land area of the city? 30%. This area belongs to the middle of Ordos subsidence tectonic basin, with strong surface erosion, developed gullies, serious soil erosion, and exposed bedrock in some areas. It is a typical hilly and gully area. Chestnut soil is the main soil type, and most of it is not suitable for farming. It belongs to the area suitable for forest and grazing, and is especially suitable for developing high-value economic forests such as pine and cypress. For fruit production, this area has superior conditions, abundant sunshine and abundant water resources, and is less affected by sandstorms. In this part of the region, there are also many wetlands and artificial silts along the river ditch, which is a good place to develop grain production. The way out for this area lies in developing forestry and animal husbandry, restoring ecological environment, comprehensively developing and utilizing local building materials and coal resources, and taking the road of forestry and animal husbandry first and industrial prosperity.
Central Kubuqi and Mu Us Sandy Land
Kubuqi and Mu Us Desert are located in the middle of Ordos City. Kubuqi Desert is adjacent to the Yellow River Plain in the north, and it is distributed in an east-west belt. Mu Us Desert is located in the hinterland of Ordos City. It is distributed in Otog Banner, Otog Qianqi, Ejinhoro Banner and Uxin Banner. The total area of the two sand areas is about 35,000 square kilometers, accounting for about 40% of the city's total area, including Kubuqi Desert with an area of 1 10,000 square kilometers and Mu Us Desert with an area of 25,000 square kilometers. Dunes in this area are mostly fixed and semi-fixed, and there are few moving crescent dunes and dune chains. Kubuqi is mostly medium-fine sand, and Mu Us is mainly medium-coarse sand, with good groundwater occurrence conditions and broad prospects for developing forestry and animal husbandry. In the future, the land transfer certificate will be implemented in this area of Ordos City. Who will govern and who will benefit? In order to promote vegetation construction, improve the ecological environment and accelerate the development of animal husbandry production.
Western slope plateau area
This area is located in the west of Ordos City, including most areas of Otog Banner and some areas of Otog Banner and Jinhang Banner, with a total area of about 2 1000 square kilometers, accounting for more than 24% of the city's total area. The area is flat with little fluctuation, with an altitude of1300-1500m. The climate here is relatively dry, with little rainfall, and the average annual rainfall is about 200 mm, which is a typical semi-desert grassland. The soil composition is mainly calcareous soil, and there is also a lot of aeolian sand in some areas. The vegetation is mainly wild plants, which is the place to develop grassland animal husbandry. At present, the people of the whole city are confidently developing vegetation construction with drought-tolerant trees, shrubs, forests and grasses as the mainstay, and exploring a new way to engage in ecological animal husbandry and efficient animal husbandry in semi-desert grasslands.
