森林经营对土壤酶活性影响的研究进展

Research advances for the effects of forest management on soil enzyme activity

为探讨土壤质量酶指标研究的新思路,把有关森林经营对土壤酶活性影响的研究资料进行了归纳总结。结果发现:林地利用方式的改变、人工林的培育模式、森林抚育措施以及林地施肥管理等各种森林生态系统经营过程,都显著改变着土壤酶活性。酶是反映森林土壤质量高低的重要生物学指标,在一定程度上也可反映森林经营措施的实施效果。今后在森林土壤酶的研究中,应重视水解酶的种类、酶指标的敏感性以及酶变化机理的探索。

Research advances about the effects of different forest management methods on soil enzyme activity were summarized in order to find new directons in the field of soil enzyme as indicator of soil quality.Results indicate that various processes of forest ecology management,for instance,different uses of forest land,silvicultural patterns of plantation,method of forest culture and tending and treatment with different fertilizers,can obviously change soil enzyme activity.As an biological indicator of soil quality,to a certain extent,soil enzyme can reflect the effects of different forest management methods.The species of soil hydrolase,the sensitivity of different enzyme indices and the change mechanism of soil enzyme should be noticed in future studies.
