摘 要:对4年生黎蒴栲工业原料林在不同坡位、不同坡向及不同坡形的生长表现进行调查分析,结果表明:不同坡位对黎蒴栲生长的影响比较大,下坡位的生长最好,中坡位次之,上坡位最差;不同坡向对黎蒴栲生长的影响,呈现出阴坡的生长最好,半阴坡次之,半阳坡和阳坡的生长稍差;坡形对黎蒴栲生长的影响,凹形坡的平均胸径、平均树高和平均冠幅显著好于凸形坡和斜形坡,凸形坡和斜形坡之间的差异不明显。Growth of the 4-year-old plantations at different slope positions,aspects,and shapes were investigated.The results were as follows: Slope position had relatively large effect on the growth of C.fissa.On the whole,The growth of C.fissa was the best in down slope,then in mid slope,the worst in up slope.Slope aspect had relatively large effect on the growth of C.fissa,The growth of C.fissa was the best in shady slope,then in semi-shady slope,relatively poor in semi-sunny slope and sunny slope.The growth of average dgh,height,and crown width of C.fissa in concave slope was significantly better than the other two kinds of slope shape.There was no marked difference of the growth of C.fissa in convex slope and inclined slope.
