Abstract:With the experimental data,the processes and dynamicsof the water,soil and nutrient losses and the effect of the treatments of cultivation and rotation systems were analyzed in hilly red soil regions. T he comprehensively harnessing techniques for eroded red soils were proposed. T he area of land subjected to soil erosion was 21. 5% of the total. The interannual variations of the water loss and soil erosion were largely up to eighteen to twenty-fold,its seasonal changes were mainly influenced by rainfall distribution,vegetation cover and human activity. The application of protected cultivation measures decreased obviously the loss of water,soil and nutrient. The development of the comprehensively harnessing techniques and the establishment of the suitable water and nutrient conditions were the effective measures for the quick rehabilitation of vegetation and soil fertility in eroded soil regions.
