The Application and Model Construction Analysis on Constitutive Resistance of Three Eucalyptus Species
Chang Ming-shan · Anhui nongye kexue · 2012
The constitutive resistance of three species of Eucalyptus was evaluated by principal component analysis,and then a comprehensive evaluation model was built up.Three principal components and the formula of principal component were pointed out.The analysis indicated that the comprehensive value of constitutive resistance of three leaf ages decreased in the order of old leaves mature leaves tender leaves,illustrating that the constitutive resistance of old leaves was better than that of tender leaves and mature leaves;the constitutive resistance of mature leaves in three species of Eucalyptus was shown as Eucalyptus robusta Eucalyptus urophyllaEucalyptus exserta,indicating that the constitutive resistance of Eucalyptus robusta were better than that of Eucalyptus urophylla and Eucalyptus exserta.
