| 摘 要： | 本文通过大量的事实和依据论述了结皮形成的物质来源和结皮的形成与土壤性质的关系，表明了粉粒（０．０５－０．０１ｍｍ）含量是结皮形成的关键，并从结皮的发育过程、剖面变化、地理位置和养分含量等方面说明了粉粒的分选和聚积过程，进而论述了粉粒的累积机理、结皮的形成过程及结皮形成－破碎的动态变化。

| Abstract: | This paper analysed the material source of soil crust formation and relation of the soil crust formation to soil properties,showed that silt(0.05-0.01mm)content is key of crust formation,simultaneously, explained process of silt scattering and assemblage from crust development process,soil profile variation,geography distribution and nutrient content etc.,the expounded assemblage mechanism of silt, formation process of soil crust and dynamic variation of formation-break of soil crust. |
