Soil Degradation of Eucalyptus Plantation and Cause Analysis
HUANG Yu-mei.Soil Degradation of Eucalyptus Plantation and Cause Analysis[J].Journal of West China Forestry Science,2004,33(4):21-26.
Authors:HUANG Yu-mei
Abstract:The soil degradation of Eucalyptus plantation was evaluated from water status, nutrition status and the integrated effect of plantation on water and fertility. Using biodiversity as the key factor, the biodiversity characteristics of both above ground and soil parts of Eucalyptus plantation were analyzed, the reasons for low biodiversity of Eucalyptus plantation were explored as well. Three measures for preventing soil degradation of Eucalyptus plantation were proposed.
Keywords:Eucalyptus  plantation  soil degradation  cause  biodiversity
