This paper deals mainly with the soil forming process and genetic properties of the allitic soils in China.(1)Investigation has shown that the genesis of the allitic soils in China is closely related with the environmental factors in tropical and subtropical regions.Allitic soils in China are developed under the interaction of the allitic and biological processes.The former is the main process of soil formation,while the latter is the premise for development of soil fertility.In addition to the geological factors,the current biological conditions,i.e.contemporary soil forming process also plays important roles on the development of the allitic soils.
