Abstract: The mixed planting of Eucalyptus grandis × E. urophylla and Castanopsis fissa was studied for exploring new ecological and economic model. The results showed that: (1) E. grandis× E. urophylla grew faster than C. fissa, and the mixed stand of E. grandis × E. urophylla and C. fissa grew faster than the pure forest; (2) the soil physical and chemical properties of the mixed planting was obviously better than that of the pure forest with the same density, the physical properties of the high density mixed stand was better than that of the pure forest, the chemical properties of the mixed planting was similar to that of the pure forest; (3) the mixed ratio of 1:1 and the density of 2500 plants/hm2 was adaptive, if the density was reduced, more E. grandis× E. urophylla should be planted than C. fissa
