【摘要】：喬灌木根系對(duì)巖土類(lèi)文物古跡的影響是近年來(lái)文物保護(hù)工作關(guān)注的熱點(diǎn)問(wèn)題,科學(xué)監(jiān)測(cè)遺址附近植物根系的空間分布、根徑等參數(shù)是土遺址風(fēng)化和機(jī)械損害機(jī)理研究的任務(wù)之一。本文運(yùn)用探地雷達(dá)技術(shù)研究了北庭故城遺址周邊榆樹(shù)根系的空間分布特征,探討了榆樹(shù)根系對(duì)城墻遺址的影響。結(jié)果表明:北庭故城4個(gè)探測(cè)點(diǎn)榆樹(shù)根系信號(hào)所體現(xiàn)的根徑信息與樹(shù)齡吻合,探測(cè)區(qū)域樹(shù)木根徑范圍50~400mm,多數(shù)在100~250mm。樹(shù)齡是影響地下根徑及空間分布的關(guān)鍵因素。綜合考慮樹(shù)齡、根徑比例、大根徑走向、樹(shù)木與遺址位置關(guān)系等因素,認(rèn)為榆樹(shù)根系對(duì)北庭城墻的威脅等級(jí)為Ⅲ號(hào)探測(cè)點(diǎn)(外城南墻中段)Ⅳ號(hào)探測(cè)點(diǎn)(外城西墻北段中)Ⅰ號(hào)探測(cè)點(diǎn)(外城西墻北段南)Ⅱ號(hào)探測(cè)點(diǎn)(外城西北角)。探地雷達(dá)技術(shù)能夠在不損害土遺址本體的前期下,實(shí)現(xiàn)對(duì)遺址及其周邊樹(shù)木根系的無(wú)損監(jiān)測(cè),在開(kāi)展植物根系對(duì)文物本體安全影響的科學(xué)評(píng)估中具有較高的應(yīng)用價(jià)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，
