Abstract
This paper studied on the growth performance of Eucalyptus plantations at different previous plantations site types,and analyzed soil fertilities after planting Eucalyptus plantation. The results indicated that the 4. 5-year-old Eucalyptus plantation had the highest survival rate( 92. 4%),diameter at breast height( 13. 5 cm), height( 18. 4 m) and per hectares wood volume( 153. 6 m3),when planting at the site type of Acacia as the previous plantation. Both the site types of Acacia and Eucalyptus as previous plantation were appropriate for several generation management of Eucalyptus plantation,and nurture management after planting were necessary for higher volume.
