This paper deals with the study by plot experiments and measurements on the difference of soil fertility change after planting Chinese fir (Cunninghamia lanceolata )and recovering broad-leaved forest on clear cutting blank during three years. The results showed that soil moisture and available water content reduced, water-physical properties became worse, wa-terstable aggregate content turned lower and dispersion ratio of structures raised in the soil under Chinese fir plantation in comparison with those of the soil under broad-leaved forest in three years. In addition,the soil nutrients continuously decreased under Chinese fir plantation and increased under broad-leaved forest.The quantity of soil microbe reduced under Chinese fir plantation and added under broad-leaved forest.Oxidation-reduction enzyme activity of soil was stronger and hydrolase activity of soil was weaker under broad-leaved forest in contrast with those of soil under Chinese fir plantation,activities of two types of enzyme systems of soil tended to be weakened under Chinese fir plantation and be strengthened under broad-leaved forest in three years.The results revealed that soil fertility was deteriorated after planting Chinese fir and was promoted after recovering broad-leaved forest in three years.
