摘要
通过对哈尔滨市山河实验林场野生黄波椤生长立地因子的调查,对黄波椤的最适生长环境进行了总结。结果表明:黄波椤在幼龄林时期,郁闭度对黄波椤单位面积蓄积的影响最大,需要一定程度的遮阴;在中林龄时期,坡向和坡位对黄波椤单位面积蓄积的影响最大,且阳坡及低坡位适宜其生长;在近熟林时期,坡向对黄波椤单位面积蓄积的影响最大,且阳坡适宜其生长。
Through research on the site factors of wild Phellodendron amurense in Shanhe Experimental Forest Farm of Harbin City,the growth environment for Phellodendron amurense were summarized,the canopy density has the greatest influence on the accumulation of Phellodendron amurense per hectare,needed a certain degree of shading;in the period of half-mature forest,the slope aspect and slope position are the dominant factors,and the sunny slope and low slope are suitable for its growth;in the period of near-mature forest period,the slope aspect is the dominant factor,and the sunny slope is suitable for its growth.
