摘要

对宁夏南部丘陵区不同植被自然恢复阶段土壤脲酶、碱性磷酸酶、蔗糖酶、脱氢酶和过氧化氢酶活性的变化特征进行了研究。结果表明：土壤脲酶、碱性磷酸酶、蔗糖酶和脱氢酶基本上随着植被封育年限的增加而增大

过氧化氢酶活性对于植被恢复年限的响应不明显。植被封育的前23年中

土壤脲酶、碱性磷酸酶、蔗糖酶和脱氢酶的活性增加明显

23年后基本趋于稳定

增加不明显。封育78年的大针茅群落下的土壤脲酶和蔗糖酶（转化酶）活性最强

其土壤中碳素和氮素营养循环强度最大。脲酶与蔗糖酶、碱性磷酸酶和脱氢酶的活性极显著相关

表明土壤酶在促进土壤有机物转化中存在共性关系。这几种酶能够在一定程度上反映植被群落的演替和植被的恢复程度

自然封育对提高土壤生物学质量有重要的作用。

Abstract

The activity of soil urease

invertase

alkaline phosphatase

dehydrogenase and catalase were studied during the process of natural vegetation succession on the Yunwu mountain area. The result showed that. The activity of soil invertase

urease

alkaline phosphatase and dehydrogenase are all increase along with the vegetation rehabilitation ages. But soil catalase has no obvious increasing with it. In the plant community which was enclosed 23 years

soil sucrase

urease

neutral phosphatase

dehydrogenase enhanced significant

especially soil sub-layer. In the plant community which was enclosed 78 years

Soil sucrase

urease are highest which showed that the turnover of soil C and N are very active. Soil urease and invertase

alkaline phosphatase

dehydrogenase are positive relative

and the activity of these enzymes can reflect the vegetation rehabilitation in the certain extent

also natural revegetation play an important role in enhancing soil biological quality.
