%X The red paleosol is widespread on river terraces in South China. It is an important resource. From the research work in the area of the middle and lower reaches of the Qiantang River the author found that:1.The distribution regularity of the red paleosol is decided by the uplift and subsidence range of neotectonics or by fault movement;2.From the upper reaches to the lower reaches, the depth of the soil profile of the red paleosol increases gradually (Fig. 3);3.On the upper terraces, the laterization often becomes stronger. This is shown by the lower SiO2/Al2O3 ratio of clay, the weaker iron activity (Fe0/Fed) the lower clay content and the lower pH value.The red paluosol can be divided into two types-Q2 and Q3. Soils derived from them aredifferent in properties. Therefore the crop choice and the land resource exploitation are also different. Besides, statistic data reveal that the area ratio of Q2/Q3 in different places changes with the characteristics of the neotectonic movement.
