土壤物理学在土壤学中是一门重要的基础学科分支。专门研究土壤固、液、气三相体系的物理现象、特性和状况,其中包括土壤颗粒、结构、水分、空气、热学特性、机械物理性质、电、磁和放射性等,及其相互间的关系。土壤物理性质对植物生长发育的影响等,也在研究之列。迄今,它的研究内容仍在继续发展,土壤物理学中的水、热、气等物质与能量的转移和运动已成
Soil physics is an important branch of science in soil science. It specializes in the physical phenomena, characteristics and conditions of soil solid, liquid and gas three-phase systems, including soil particles, structure, moisture, air, thermal properties, mechanical and physical properties, electricity, magnetism and radioactivity, and their mutual relations . Soil physical properties of plant growth and development, etc., are also studied. So far, its research is still continuing to develop. The transfer and movement of matter and energy such as water, heat and gas in soil physics have become
