The paper studied soil enzyme characteristics of main shelter forest types in the rocky coastal area of the subtropical zone. The results were as follows: Among three kinds of phosphatase, acid phosphatase activity was more than neutral and alkaline phosphatase activity. They had a close relationship with the total phosphatase activity. But the relationship coefficient of alkaline phosphatase was the highest, neutral phosphatase the second, and acid phosphatase the third. From top to bottom of soil profile, the enzyme activity reduced gradually. Soil enzyme activity in different forest types had a significant difference. Soil enzyme activity increased with forest age increasing. Because of artificial disturbance, soil enzyme activity of no timber forest lands was at the middle or low level, which needed reasonable and scientific management.
