Soil in Qingdao:
According to the land classification system of the second national soil survey, Qingdao's soils mainly include brown soil, Jiang Sha black soil, fluvo-aquic soil, cinnamon soil and saline soil. Brown soil covers an area of 493,700 hectares, accounting for 59.8% of the total soil area. It is the most widely distributed soil type in Qingdao, mainly distributed in mountainous hills and piedmont plains.
The degree of soil development is affected by the topographic position, and it can be divided into three soil genera from high to low: brown soil, brown soil and moist brown soil. Brown soil is mainly used in forestry and animal husbandry because of its high topographic position, large slope, thin soil layer, heavy erosion and low fertility. Brown soil and moist brown soil are the main crops in Qingdao.
The area of black soil in Jiang Sha is 654.38 076.9 thousand hectares, accounting for 265.438 0.42% of the total soil area. It is mainly distributed in shallow depressions in the south of Laixi, southwest of Pingdu, northwest of Jimo and north of Jiaozhou. This kind of soil has deep soil layer, high viscosity, light to heavy topsoil, poor physical properties, uncoordinated hydrothermal conditions and low available nutrients.
The fluvo-aquic soil area is144,900 hectares, accounting for 17.55% of the total soil area. Mainly distributed in the plains of the lower reaches of Dagu River, Guwu River and Jiaolai River. Because of the different distance from the river, the soil texture and soil configuration are quite different. Coastal areas are often influenced by sea salt to form salinized fluvo-aquic soil, and soil fertility and utilization direction are quite different.
The cinnamon soil covers an area of 6,333.33 hectares, accounting for 0.77% of the total soil area, distributed in the middle and upper parts of limestone residual hills in Pingdu, Laixi and Jiaonan, and the saline soil covers an area of 3,666.67 hectares, accounting for 0.44% of the total soil area, distributed in coastal lowlands and coastal beaches.
