Soil type for each climatic zone

Soil can be divided into three types: sandy soil, clayey soil, and loam.

The main types of soil occurrence in China can be summarized into red soil, brown soil, brown soil, black soil, chestnut lime soil, desert soil, fluvial soil (including sand ginger black soil), irrigation and silt soil, paddy soil, wet soil (meadow, swamp soil), saline-alkali soil, lithologic soil and alpine soil.

According to the soil texture, the soil is generally divided into three categories: sandy soil, clayey soil, and loam.

The properties of sandy soil: high sand content, coarse particles, fast water seepage, poor water retention performance, and good aeration performance.

The properties of clayey soil: low sand content, fine particles, slow water seepage, good water retention performance, poor aeration performance.

The nature of loam: general sand content, general particles, general water seepage rate, general water retention performance, general ventilation performance.

Differentiation and assemblage of soil species on the Earth's land surface. It is closely related to the comprehensive change of physical geographical conditions.

1. The types of soil occurrence in China can be summarized into red soil, brown soil, brown soil, black soil, chestnut lime soil, desert soil, fluvial soil (including sand ginger black soil), irrigation and silt soil, paddy soil, wet soil (meadow, swamp soil), saline-alkali soil, lithologic soil and alpine soil.

2. Black soil: Daxing'an Mountains.

The east and west sides of the mountains in the central and southern sections, the central part of the Songnen Plain in the northeast and the Songhua River.

The watershed area of the Liao River. Temperate semi-humid continental climate. The average annual temperature is minus 3 degrees Celsius.

3 degrees Celsius, annual precipitation 350 500 mm. The vegetation is temperate grassland and meadow grassland with the highest grass yield. The humus content is the most abundant, the thickness of the humus layer is large, the soil color is mainly black, showing a neutral to slightly alkaline reaction, calcium, magnesium, potassium, sodium and other inorganic nutrients are also more, and the soil fertility is high.

3. Brick red soil: Hainan Island, Leizhou Peninsula.

Xishuangbanna and Taiwan Island.

South, roughly located south of 22 degrees north latitude. Tropical monsoon climate. The average annual temperature is 23 26 degrees Celsius and the average annual precipitation is 1600 2000 mm.

The vegetation is tropical monsoon forest. The weathering leaching effect is strong, the soluble inorganic nutrients are lost in large quantities, and the iron and aluminum remain in the soil, and the color is red. The soil layer is deep, the texture is sticky, the fertility is poor, and it is acidic to strong. Acidity.

Soil type refers to the comprehensive performance of soil composition, texture, structure, color, moisture and nutrients. Knowing the soil type of an area can be obtained by querying on a specialized data platform.

Soil types are distinguished by the granularity of the constituent minerals:

0.Non-terrestrial locations.

1.Sandy soil (stout).

2.Muddy and sandy soil (medium).

3.Sandy loam soil (medium-fine).

4.Loam (fine).

5.Loamy silt (very fine).

6.Organic soils (e.g. peat or peat).

7.Historical soils (tropical organic matter soils).

Step 1: Confirm the geographic location information (you can choose single-point data or regional average data), the data source (you can choose Xihe Data Source, European Medium-Range Meteorological Center, and NASA for historical data), and the required query time (within 40 years of history and the next 7 days).

<>Step 3: Select Soil Type in the Soil section of the attribute list

The types of vertical distribution of soil temperature are:Radiation, radiation, early morning transition.

1. Sunlight type.

The type in which the temperature of the soil decreases with increasing depth is called the solar type. The radiation type generally occurs during the day or in summer, and it is mainly caused by the first heat on the soil surface, which is the multiplied distribution of the soil temperature at 12 noon on a day and in July of the year.

2. Radiation type.

The type in which the temperature in the soil rises with increasing depth is called the radiant type. The radiant type generally occurs at night and in winter, and it is caused by the first cooling of the soil surface.

3. Transitional.

The type of both the radiation type and the radiation type is called the hybrid type. The mixed type is generally in the transition period between day and night and winter and summer.

There are 4 types: Sunlight type, radiation type, early morning transition type, and evening transition type.
