Establishment of Approach to Archaeology and History by Analyzing the Data of Tree-ring Pattern

在1985年开始的重大研究中，我们已经实现了最初提出的目标。(2)我们利用一棵日本柏树（hinoki）建立了一个公元前317年的索引主年表。与此索引主年表进行交叉匹配，使我们能够建立日本，雪松和伞松的主年表。我们有一个日本雪松的年轮图案，时间跨度从公元1285年到405年，还有一个是在1986年到1779年之间用一棵现代树木建造的。我们还确认了一棵伞形树的年轮图案，时间跨度从公元741年到公元186年。我们还有一些“浮动年表”需要交叉确定时间。由于通过匹配年轮模式来建立一个主要的年代学是树木年代学研究的基础，我们仍然继续努力追溯到更早的过去。我们还探索了将其应用于其他领域的可能性。比如考古学。历史，建筑史，艺术史，以及自然灾害的历史，在每一个案例中，我们都有一个很好的未来成功的前景。此外，我们在树木气候学方面也取得了进展。(4)我们成功地对旧石器时代样品的环状图案进行了交叉匹配，这是极不寻常的。这表明我们将来有可能将索引主年表扩展到旧石器时代。(5)这些结果表明，我们已经牢固地建立了利用树木年代学资料进行历史和考古研究的方法。

(1) In our major study launched in 1985, we have achieved the goals we had originally proposed. (2) We have built an index master chronology up to 317, B.C. utilizing a Japanese cypress (hinoki). Cross-matching with this index master chronology enabled us to build master chronologies of a Japanese, cedar and an umbrella pine. we have a ring pattern of a Japanese cedar spanning from 1285 to 405 A.D., besides one between 1986 and 1779 built utilizing a modern tree. We also confirmed a ring pattern of an umbrella tree covering the period 741 to 186, A.D. We still have some "floating chronologies" to be cross-dated. Since building a master chronology by matching ring patterns is the basis of dendrochronological research, we still continue our effort to date back further in the past. (3) We have also explored the possibilities of the applications to other fields. such as archaeology. history, architectural history, art history, as well as the history of natural disasters, and in every case, we have a good prospect for future success. Further, we have made progress in dendroclimatology. (4) We are successful in cross-matching of ring patterns of Palaeolithic samples, which is extremely unusual. This indicates a future possibility that we extend our index master chronology to the Palaeolithic Period. (5) These results show that we have firmly established the approaches to history and archaeology by utilizing dendrochronological data.
