慈利白公城遗址出土木材种属的鉴定研究

慈利白公城遗址历史悠久,具有重要的考古价值。该遗址出土了大量木质井壁及少量其他木质文物,为了解这些木材的特点,以及为木材保护提供相关的参考,通过徒手切片,并利用光学显微镜对该遗址出土的10件木质样品进行鉴定。结果表明其中1件为无患子(Sapindus. mukorossi Gaertn.),1件为冷杉(Abies fabri(Mast.)Craib),2件为湖南杨桐(Adinandra. acutifolia Hand.-Mazz.),2件为香椿(Toona sinensis A. Juss.),4件为润楠(Machilus pingii Cheng ex Yang)。通过实验结果,初步推测井壁的制作在当时是比较重要的工作,此时已经在选择性地使用木质井壁原料。从树种适宜生长的环境上看,同时期该遗址附近可能是以阔叶材为主的针阔叶混交林,气候温暖湿润。

Identification of ancient wooden cultural relics from Baigongcheng Site in Cili County

The Site of Baigongcheng in Cili County has a long history and important archaeological value. A large number of wooden walls were unearthed from the ancient well and a few wooden cultural relics were unearthed from ash pits. This study was carried out in order to comprehend the characteristics and development of the ancient well and materials of daily use in this area, as well as means of wood protection in ancient times. The micro-character of 10 samples from the site was observed by means of optical microscope. It was found that one was Sapindus. mukorossi Gaertn, one, Abies fabri (Mast.) Craib, two were A. acutifolia Hand.-Mazz., two were Toona sinensis A. Juss. and four Machilus pingii Cheng ex Yang. It is preliminarily inferred that the making of well wall was an important work and the wood of well wall was conscientiously used at that time. It also indicates that this area was a mixed coniferous and broad-leaved forest composed mainly of broad-leaved wood that grew in the warm and humid climate in ancient times. The results also provide corresponding information for the protection of wooden relics unearthed in this site.
