| 摘 要： | 应用地形5个因子在2个水平下的正交试验设计方法,系统分析了闽东高海拔山地14年生杉木人工林生长的变化规律,结果表明:影响杉木人工林胸径、树高的各地形因子的重要程度依次为:坡形>坡位>坡向>海拔>坡度,影响杉木人工林冠幅的各地形因子的重要程度依次为:坡形>坡位>坡向>坡度>海拔,影响杉木人工林枝下高的各地形因子的重要程度依次为:坡形>坡位>海拔>坡向>坡度。坡形对杉木人工林胸径、树高和枝下高影响显著,坡位对杉木人工林树高影响显著。影响杉木人工林生长的最重要地形因子是坡形,其次是坡位,坡向、海拔和坡度(在45°以内)对杉木人工林生长影响不显著。

| Abstract: | The orthogonal design with five terrain factors under two levels was performed to systematically analyze the variation rules on growth of 14-year-old plantation Chinese fir.The results of each terrain factor affecting diameter and height of the plantation Chinese were obtained.The affecting intensity was slope shape>site>direction>altitude>gradient.The affecting intensity on its crown width was slope shape>site>direction>gradient>altitude.The affecting intensity on its height under branches was slope shape>site>direction>altitude>gradient.Slope shape was the most important factor which affected diameter,height and height under branch of plantation Chinese fir.Slope site was the second important factor which only affected height of plantation Chinese fir.The first affection factor affecting on the growth of plantation Chinese fir was slope shape,then slope site.Slope direction,altitude and gradient(<45°) were not the significant factors affecting plantation Chinese fir. |
