| Abstract: | The stationary observation on soil and water for three years in young forest of Chinese fir showed that the lost amount of soil and water and nutrient was lowered down greatly after tending and piling up soil around the level terrace and decreased with the increase of time. The yearly lost amount of soil was almost the same as the natural soil erosion amount.Lost amount of soil water and nutrient in non forested land obviously decreased with time. The nutrient concentration of the soil and water decreased with time. Lost amount of soil of non forest land is 1.72 times as that of the young forest land. The factors of effect on losses of soil and water from young forest land were analysed through applying model I of mixed quantification,and the prediction equations of lost amount of soil and water were established. |
