土壤是地球上岩石圈、大气圈、水圈和生物圈交界面上的一个独立的历史自然体。是人类赖以生存的重要资源,也是人类和陆地生物栖息和繁衍的基地。土壤的发生、发育和演变过程,既是自然界物质循环和能量转换过程的组成部分,又是人类生存环境变化的具体反映。土壤学与环境科学、地学、生物学及农学等的关系至为密切,并与这些学科交叉发展。因此
Soil is an independent historical natural body on the Earth’s interface between lithosphere, atmosphere, hydrosphere and biosphere. It is an important resource for mankind to survive and a base for the habitat and reproduction of mankind and terrestrial creatures. The process of the occurrence, development and evolution of soil is not only an integral part of the process of material circulation and energy conversion in nature, but also a concrete reflection of the changes of human living environment. The relationship between soil science and environmental science, geosciences, biology and agronomy is closely related and develops with these disciplines. therefore
