坡向、坡位对桉树人工林生长的影响

The Effects of Slope Direction and Slope Position on the Growth of Eucalyptus plantation

为了解坡向、坡位对桉树人工林生长的影响,该研究对不同坡向、坡位的2年生桉树人工林进行了测量分析。结果表明:(1)坡向对桉树树高有显著影响,对胸径无显著影响;(2)阳坡的桉树树高最高、胸径最大;(3)坡位对桉树树高有显著影响,对胸径无显著影响;(4)中坡的桉树树高最高,下坡的桉树胸径最大,但中坡的胸径与之无显著差异。可见考虑到经济效益,在种植桉树时,应尽量种植在阳坡、半阳坡、中坡。

In order to understand the influence of slope direction and slope position on the growth of Eucalyptus plantation.The results of this study showed that:(1)the slope direction had a significant effect on the height of Eucalyptus,but had no significant effect on the DBH;(2)Eucalyptus on the southern slope had the highest height and the largest DBH;(3)Slope position had significant effect on Eucalyptus height,but not on DBH;(4)The height of Eucalyptus on the middle slope was the highest,and the DBH of Eucalyptus on the downhill slope was the largest,but there was no significant difference in DBH of Eucalyptus on the middle slope.Therefore,considering the economic benefits,when planting Eucalyptus,we should try to plant in the east slope,south slope and middle slope.
