摘要/Abstract

摘要： 运用典范相关分析研究了桉树人工林地土壤酶活性和土壤微量元素含量关系.结果表明,Zn和Mn对土壤蛋白酶活性的促进作用最大.Zn在一定程度上对脲酶和过氧化氢酶有抑制作用;而Mn对脲酶和过氧化氢酶有促进作用.结合林地生物的生长特征等因子,“综合土壤酶因子”可作为土壤肥力评价的一个指标,对桉树林地土种的划分有一定意义.

Abstract: Canonical correlation analysis on soil enzyme activities and trace element contents in Eucalyptus plantation soil showed that among the test elements, only Zn and Mn affected enzyme activity. Both Zn and Mn increased soil proteinase activity. Zn decreased the activities of soil urease and peroxidase, while Mn promoted them. "Integral soil enzyme factor" could be used as an index of soil fertility. Together with other growth factors, this index should be considered when evaluating soil fertility of Eucalyptus forest sites. It also had a definite significance on the division of Eucalyptus soil families.

Key words: Eucalyptus plantation soil, Soil enzyme, Soil trace element, Canonical correlation analysis, community structure, environmental factor, diversity, contributor., zooplankton
