摘　　要：选择广西6个江南油杉(Keteleeria fortunei var.cyclolepis)种植点,设置标准地进行林木生长指标测定,以5株优势木生长指标进行方差分析,探讨不同坡向、坡位、坡度对江南油杉人工林生长的影响。结果表明:江南油杉人工林在阳坡的生长优于阴坡;在下坡的生长优于中坡,在上坡的生长为三种坡位中最低;在斜坡的生长水平优于平坡。By selecting 6 plantation sites of Keteleeria fortunei var. cyclolepis in Guangxi, we established the standard plot to investigate the tree growth index, and chose 5 dominant trees with analysis of variance of the tree growth index. The different slope aspects, slope positions, slope gradients, which had influence on theK.fortunei var.cyclolepis plantation, were discussed. The results showed that the plantation in the sunny slope was better than that in the shady slope, the growth of plantation in the downhill was better than that in the middle position, the growth of plantation in the uphill was the lowest of three kinds of slope position, the growth of plantation in the slope was better than that in the flat slope.
