Abstract: Study on the effect of different spacing on the typhoon resistance of young Eucalyptus plantation showed that "wide row spacing and narrow tree spacing" is the best planting spacing to resist typhoon. The effect of 4.5 m row spacing is better than that of 3 m line spacing if their narrow tree spacing is the same. The effect of 1 or 1.5 m tree spacing is better than that of 3 or 2.5 m tree spacing if their wide row spacing is the same. Planting spacing of 3 m×3 m is the worse one.
