摘  要：
运用探地雷达技术对黄帝陵轩辕庙内19棵古柏的树干空洞和粗根分布规律进行了检测。轩辕庙19棵古柏均有不同程度的空洞情况,其中1、4、12、16、17号相对空洞程度较高,有向重度空洞方向发展的趋势;3、5、8、18号属轻度空洞。粗根在垂直方向上主要分布在0~60cm土层,水平方向上粗根主要分布在4m范围内。经过对比粗根分布规律发现,古柏生长健康状况与粗根分布的健康状况相关:在水平方向上健康和亚健康古柏分布范围>不健康古柏,并且在垂直层次中粗根密度由大到小依次是健康>亚健康>不健康;人为踩踏区域与未踩踏区域相比,粗根密度低于未踩踏区域;经过根系复壮的古柏较未经过根系复壮的古柏粗根密度更大,并且水平分布范围相对较广。

摘  要：
Ground penetrating radar technology was applied to examine the trunk decay situations and the thick root distribution characteristics of the ancient Platycladus orientalis trees occurring in Xuanyuan Temple of the Tomb of Yellow Emperor.Cavities were observed in 19 ancient P.orientalis trees with different degrees,among which trees of No.1,4,12,16,and 17 were more serious,and had a tendency to develop more severe holes.No.3,5,8,and 18 trees presented less serious degrees of trunk cavity.The thick roots mainly distributed vertically in 0-60 cm soil layer and horizontally 4maround the trunk.After comparing the distribution patterns of the thick roots,it was found that the health status of the trees and roots were closely correlated:in the horizontal direction,the distributions of health and sub-health thick roots were greater than unhealty roots,and in the vertical hierarchy thick root density decreased in the order of healthy> sub-health> unhealthy.The thick roots density of the area without trampling was greater than the area with human trampling.After the treatments of root rejuvenation,the thick roots density and horizontal distribution area increased.
