土壤是由气候、生物、地形、母质及时间五个成土因素综合作用下发生发展的。在不同的地区,土壤形成的条件不同,所以在不同地域范围内就有不同的土壤类型发生和分布而表现出土壤的地域性。土壤地域性又有地带性与地方性的表现。一般把土壤的形成和分布与大气候、生物带的一致性称土壤地带性,在陆地表面呈带状分布,所以又称地带 Soil is a combination of climate, biology, topography, parent material and time under the combined effect of five factors developed. In different regions, the conditions for the formation of soils differ. Therefore, different soil types occur and are distributed in different regions to show the geographical features of the soil. Soil regional and regional and local performance. Generally the formation and distribution of the soil and the climate, the consistency of the biological zone called the soil zonation, was banded in the surface of the land distribution, also known as the zone
