| 摘 要： | 研究了我国亚热带基岩海岩主要防护林类型土壤酶活性持征，指出在3种磷酸酶中，酸性磷酸酶活性大于碱性，中性磷酸酶活性。3种磷酸酶与总磷酸酶活性密切相关，但以碱性磷酸酶相关性最高，中性磷酸酶次之，酸性磷酸酸最小。4类土壤酶活性自上而下均逐渐减少。不同森林类型土壤酶活性差异显，林龄越大活性越高，经济林受人为干扰，土壤酶活性居中低水,应采用合理的经营管理措施。

| Abstract: | 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. |
