红松阔叶混交林不同演替阶段土壤过氧化氢酶活性的研究

Soil Catalase Activity of Broad Leaved Mixed Forest of Pinus koraiensis at Different Succession Stages

红松阔叶混交林是我国东北地区最重要的森林类型之一,对保持生态系统的多样性具有重要意义。采用对比分析的方法研究了红松阔叶混交林不同演替阶段土壤肥力以及土壤过氧化氢酶活性的变化,揭示了红松阔叶混交林不同演替阶段土壤过氧化氢酶活性与土壤养分的相关关系的演变规律。

Broad leaved mixed forest of Pinus koraiensis, which have important significance to keep biodiversity of ecosystem ,is one of the important forest types in north of China. Soil fertility at different succession stages ＆ variation of soil eatalase activity were studied by using comparative analysis ; evolution law of correlation of soll catalase activity ＆ soil nutrient of broad leaved mixed forest of Pinus koraiensis at different succession stages is revealed.
