This paper reported severe degradation of soil organic matter and nutrient pool under CF (artificial Chinese fir forest). Remarkable drop of litter matter and its nutrients under CF were observed compared with those under BF (natural broadleaped forest) and MF (artificial mixed forest of Chinese fir and broad-leaved forest).And similar drop trends of soil OM content and total N and hydrolyzed N in soil profile distribution were also found. The degradations of litter layer and nutrient pool under CF were abruptly as the conventional reforestation was implemented. In addition,an unitary composition of standing forest with less litter and nutrients returned to soil is another factor inducing the degradation of organic nutrient pool. It is suggested that the degradation of soil organic matter and nutrient pool could be control by improving forest regeneration technique and forest component.
