This paper deals mainly with the soil forming process and genetic properties of the allitic soils in China.(1)Based on the data of the macro and micro-morphological characteristics,the fertility properties and other synthetic indicative features,various diagnostic horizons and their structural patterns relating to the different soil categories have preliminarily been established and distinguished. (2)By using of the results mentioned above,the new genetic and morphological classification principles for the allitic soils were suggested.The principles include three main aspects,i.e.the geographical genesis factors,the soil properties and morphological features, the soil forming process and its conditions,which provide the basis for the systematic and automatic classification for the allitic soils in China.
