Abstract

Abstract: The growth of mixed stand of Eucalyptus urophylla and Acacia mangium with different mixed proportion were investigated in 3 year-old forest.The results showed that in the density of 1727·hm^-2,the average DBH,height and single-tree volume were 9.27cm,14.50m,0.0514m³ respectively.And the mixed stand of Eucalyptus urophylla and Acacia mangium has the mixed proportion at 1∶1.6 and the above indexes were 13.50cm,15.97m and 0.1098m³,which increased 45.6%,10.1%,113.6% higher than that of Eucalyptus urophylla pure stand.The mixed stand with 98.00m³/hm² forest volume was 10.3% higher than the pure stand with 88.83m³/hm² forest volume.The different mixed treatments have significant difference in the average DBH,height,tree volume and ratio of diameter to height.

Key words: mixed stands, Eucalyptus urophylla, Acacia mangium
