摘  要:
通过实地调查,对坡垒随地形因子(海拔、坡向、坡度)的分布规律进行了分析。结果表明,坡垒分布主要集中在中低海拔600~900 m,先随海拔增高而增加,海拔700~800m时候达到最高值,随后随海拔升高而减少;不同坡向对坡垒数量分布影响为:北坡>西南坡>东北坡>南坡>西北坡>西坡>东南坡>东坡,阴坡上分布的坡垒数显著高于阳坡上的分布数量;坡垒集中分布在坡度20~25°范围内。可见坡垒的分布格局与海拔、坡向及坡度密切相关。

摘  要:
The distribution law of Hopea with topographic factors(altitude,slope of aspect,slope) were studied by investigation method. The results showed that the number of Hopea with the increase of altitude first increased and then decreased.The number of Hopea in different slope of aspects was north aspect>southwest aspect>northeast aspect>south aspect>northwest aspect>west aspect>southeast aspect>east aspect,and the number in sunny slope of aspect was significantly Less than in shady slope of aspect.The number was the most in the range of grade slope 20~25°.The distribution pattern of Hopea was closely related to altitude, slope of aspect and slope.
