title: [Relationship between soil enzyme activities and trace element contents in Eucalyptus plantation soil].
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.
