Abstract: The study was made in, 1982—1985 for pure stand of 8 years old Chinese fir (A), pure stand of Homana (B), mixed stands C(A:B=8:2) and D (A:B=5:5). 1. The total accumulation of nutrient in tree layer were estimated to be 852.4, 624.2, 971.6 and 782.4kg/ha, and the total annual accumulation were 113.3, 93.5, 184.5,and 95.8kg/ha respectively. 2. The mean annual amount of litterfall shows B>D>C>A. 3. By returning the litters of Homana to the soil,the content of soil organic matter was increased, and the soil fertility and nutrient cycling were improved. Ratio of annual return to annual uptake of pure Homana or mixed stands were higher than that of pure Chinese fir stand.
