【摘要】：乔灌木根系对岩土类文物古迹的影响是近年来文物保护工作关注的热点问题,科学监测遗址附近植物根系的空间分布、根径等参数是土遗址风化和机械损害机理研究的任务之一。本文运用探地雷达技术研究了北庭故城遗址周边榆树根系的空间分布特征,探讨了榆树根系对城墙遗址的影响。结果表明:北庭故城4个探测点榆树根系信号所体现的根径信息与树龄吻合,探测区域树木根径范围50~400mm,多数在100~250mm。树龄是影响地下根径及空间分布的关键因素。综合考虑树龄、根径比例、大根径走向、树木与遗址位置关系等因素,认为榆树根系对北庭城墙的威胁等级为Ⅲ号探测点(外城南墙中段)Ⅳ号探测点(外城西墙北段中)Ⅰ号探测点(外城西墙北段南)Ⅱ号探测点(外城西北角)。探地雷达技术能够在不损害土遗址本体的前期下,实现对遗址及其周边树木根系的无损监测,在开展植物根系对文物本体安全影响的科学评估中具有较高的应用价值。
[Abstract]:The influence of the roots of trees and shrubs on geotechnical cultural relics and monuments is a hot issue in the protection of cultural relics in recent years. The spatial distribution of plant roots in the vicinity of the sites is monitored scientifically. Root diameter and other parameters are one of the tasks in the study of weathering and mechanical damage mechanism of earth sites. In this paper, the spatial distribution characteristics of elm root system around Beiting ancient city site are studied by using ground penetrating radar technology, and the influence of elm root system on city wall site is discussed. The results showed that the root diameter information reflected by the root signals of elm trees at four detection sites in Beiting City coincided with the age of trees. The root diameter range of trees in the detection area was 50 ~ 400 mm, and most of them were in 100 ~ 250 mm ~ (- 1) 脳 10 ~ (- 1) mm. Tree age is the key factor affecting underground root diameter and spatial distribution. Comprehensive consideration of tree age, root diameter ratio, large root diameter direction, the relationship between trees and site location, and so on. It is considered that the threat level of elm root to Beiting wall is the detection point 鈪，
