摘要

High altitudinal soils (Entisols and Ultisols) on different landscapes in Arunachal Pradesh were studied with respect to the role of erosion in soil formation. Soil development and its accumulation is obliterated by severe soil erosion, causing theformation of Entisols which are degraded under the present day conditions. On the other hand, huge clay illuviation in the soils (Ultisols) indicates a relatively stable landscape at lower elevations whereas a higher elevations there is a rapid degradation process indicated by the truncation of the upper soil layers. In the erosion dependent landscape of the northeastern region of India, the series of ridges, valleys, terraces and scarps are the results of differential erosion. A soil study to determinedegradation and landscape stability is recommended.
