| 摘 要： | 目的]研究坡向对西南桦人工林造林的影响。方法]在造林试验地内海拔约450、550和600m处的阳坡、半阳坡、阴坡和半阴坡设置调查样地，重复3次，进行西南桦人工造林试验以评价坡向对西南桦生长的影响。结果]坡向对西南桦高、径、材积生长均有显著影响。不同坡向平均树高从高到低排序为阴坡、半阴坡、半阳坡、阳坡，平均树高阴坡比阳坡高7．9％；不同坡向平均胸径从高到低排序为阴坡、半阴坡与半阳坡、阳坡，平均胸径阴坡比阳坡大11．1％；不同坡向平均单株材积从高到低排序为阴坡、半阴坡、半阳坡、阳坡，平均单株材积阴坡比阳坡多33．0％。结论]坡向对西南桦的生长影响显著，阴坡西南桦的生长状况优于阳坡。
