摘要/Abstract

摘要： 为探讨一定收割年限后芦苇湿地土壤酶活性的变化，以苏州太湖旅游度假区湖滨湿地人工恢复的芦苇群落为研究对象，采用野外控制实验方法，研究了芦苇收割移出和自然保留两种处理下湖滨湿地土壤脲酶、过氧化氢酶、碱性磷酸酶和蔗糖酶的活性变化。结果表明：土壤蔗糖酶活性对芦苇收割最为敏感，碱性磷酸酶次之，脲酶和过氧化氢酶活性在两种处理下没有表现出显著的差异；土壤有效磷在两种处理对应土层的差异性都较为显著，而其他土壤养分含量在两种处理下差异不显著。相关分析表明：土壤脲酶、碱性磷酸酶和蔗糖酶活性与有机质、全氮和有效磷极显著相关。说明芦苇收割导致土壤养分含量变化可能是土壤酶活发生变化的主要原因之一。

Abstract: In order to explore the effect of reed cutting on soil enzyme activities after a certain number of years,the field control experiments were adopted to determinate the activities of soil enzymes (including urease, catalase, alkaline phosphatase and invertase) taking reed community of artificial restoration in Taihu Lake National Tourism Resort, Suzhou City, as the object. The results indicated that: soil invertase activity was the most sensitive under the reed cutting,followed by alkaline phosphatase. Further, it did not exist significantly in urease and catalase activity of two treatments. Soil chemical proporties were no significant differences except available phosphorus in two treatments. The correlation analysis showed that: it was a very positive correlation significantly among soil urease, alkaline phosphatase and invertase activity and organic matter, and the total nitrogen and phosphorus. It was indicated that the changes of soil nutrients due to reed cutting were the principal reason to soil enzyme activities.
