Abstract: ObjectiveIn present study, afforestation effects and economic benefit of Parashorea chinensis-Eucalyptus mixed plantation were analyzed in order to provide reference for promotion of the mixed palantation model. MethodFixed quadrate method was adopted to measure the growth of P. chinensis -Eucalyptus mixed plantation for three consecutive years. Meanwhile, afforestation costs and benefits were analyzed using net present value method. ResultIn five-year-old P. chinensis-Eucalyptus mixed plantation, average tree height of P. chinensis was 3.31 m, average annual growth of tree height was 0.66 m; average diameter at breast height(DBH) was 3.04 cm, and average annual growth of DBH was 0.61 cm. In terms of Eucalyptus, average annual growth of DBH was 15.63 cm,that of tree height was 17.79 m and that of volume was 99.00 m3/ha. In the 5th year of investment, financial net present value was 630.00 yuan/ha, financial internal rate of return 12.57%,average annual profit 3774.00 yuan/ha and annual average profit rate 10.61%. ConclusionP. chi-nensis-Eucalyptus mixed plantation is an ideal afforestation mode considering it afforestation effects and economic benefits.
