A Study of the Timber Selection of Wood Coffins in the Kofun Period

本研究以古坟时期的古墓为研究对象，对出土的木棺材料进行了研究，尝试以考古学的遗迹学理论为基础进行研究。本研究的主要内容如下：进行了木棺的树种鉴定，并积累了调查实例。同时建立了全国范围内出土棺材树种调查实例数据库，并在此基础上分析了各时期出土棺材树种的区域性/层次性特征及其变化。收集了165个样本的木材树种鉴定数据。裸子植物（针叶树）和被子植物（阔叶树）的比例为91%：9%。特别是，日本伞松（Sciadopitys verticillata）的使用占整体的51%，我们可以看到日本伞松棺材的分布明显倾向于限制在近畿地区和周边地区。与其他树种一样，有少量的日本木材， ...更多信息 dars（Cryptomeria japonica）和日本扁柏（Chamaaparis obtusa），但日本伞松所看到的明显的使用选择性在这些中没有被认识到。在近畿及其周边地区，古坟时代早期和中期，日本伞松的比率接近90%。然而，这一比率在古坟时代后期和公元世纪有所下降。D.不再观察到选择性。认为造成这种状况的因素是大量消耗日本伞松木材造成的资源短缺。由于日本伞松林的选择性使用区域的框架在古坟时代没有改变，因此假设存在一定的木材供应系统，供应日本伞松林。此外，在公元6- 7世纪，为百济皇陵提供日本伞松木棺材。D..这是一个有趣的事实，表明它参与了日本帝国主权体系。少

In this research, we examined the materials for wood coffins excavated from tumuli in the Kofun Period, as making trial of a research based on the theory of archaeological remains study. The outline of this research is as follows; We carried out wood species identifications of wood coffins, and accumulated investigation examples. Simultaneously we made a nationwide database of investigated examples of the wood species of excavated coffins, and based on them, analyzed regionality/hierarchy characteristics and some changes for the each stages. The identified wood species data of 165 examples has becollected. The ratio of Gymnospermae (needle-leaf trees) and Angiospermae( broadleaf trees) is 91%: 9%. Especially, use of Japanese umbrella pine( Sciadopitys verticillata) form 51% of the whole, and we can see a clear tendency for a distribution of Japanese umbrella pine coffins to be restricted to the area of Kinki district and the periphery. As other wood species, there are a little Japan ce … More dars (Cryptomeria japonica) and Japanese cypresses (Chamaecyparis obtusa), but the clear selectivity of use which is seen by the Japanese umbrella pines is not recognized in these. In the area of Kinki and the periphery the rate of Japanese umbrella pines is near 90% at the early and mid Kofun Period. However, this rate decreased in the late Kofun Period, and in the 7th century A. D. the selectivity no longer was seen. It is thought that the factor of this situation was lack of the resources by mass consumption of Japanese umbrella pine woods. Since the framework of the selective use area of Japanese umbrella pine woods did not change through the Kofun Period, the existence of a certain timbers supply system which supplied Japanese umbrella pine woods is assumed. Moreover, supplying with Japanese umbrella pine timbers for coffins to the Baekjae Imperial mausoleums was performed in the 6-7th century A. D.. This is interesting as a fact which suggests a participation in the system of the Japanese Imperial sovereignty. Less
