Abstract: In this paper, studies were made of the optimal technologies about the basic materials of the pure eucalyptus wood, pure polar wood and eucalyptus-polar composite flooring through orthogonal method, and then different assembly forms of eucalyptus and polar were designed to research the performance of the eucalyptus wood, polar wood and eucalyptus-polar composite flooring. The experimental results showed that the eucalyptus and polar combination to produce parquet was feasible, and the comprehensive performance of the fifth form, which had three poplar veneers placed in the middle, and then symmetrically placed four eucalyptus veneers, was better than the pure eucalyptus, pure polar and other forms.
