摘　　要：通过实测林木树高与地径以探讨地形对其生长的影响,为伯乐树造林地选择提供参考依据。在不同坡位和坡向设置标准地,对标准地数据进行分析,不同坡位和坡向对树高和地径生长均有显著影响。结果表明:不同坡位平均树高和平均地径顺序大小依次为下坡位>中坡位>上坡位;不同坡向平均树高和平均地径顺序大小依次为北坡向>东坡向>西坡向>南坡向。下坡位平均树高达2.45 m,平均地径达4.38 cm;北坡向平均树高达2.69 m,平均地径达4.84 cm。可见,伯乐树造林地最宜选择下坡位的北坡向。The influence of terrain on the growth of Bretschneidera sinensis was discussed by measuring the tree height and ground diameter,which provided reference for the selection of B.sinensis land.The standard site was set in different slope position and slope direction,and the standard site data was analyzed.Different slope position and slope direction had significant effects on tree height and ground diameter growth.The results showed that order of average tree height and average diameter of different slope positions was descending position>middle slope position>ascending slope position.The order of average tree height and average diameter in different slope orientations was north slope,east slope,west slope and south slope.The average height and diameter of trees on the lower slope were 2.45 m and 4.38 cm respectively,and those on the north slope were 2.69 m and 4.84 cm respectively.the north slope of downslope is the best choice for B.sinensis Plantation.
