Dendrcchronologcal Research on The Gigantic Eruption of Changbai Mt, and Bo Hai Quo in China

长白落叶松活体年表：在开展本研究前，利用长白山西麓采集的岩心标本，将长白落叶松的平均年表(1836-1992年)扩展到1804年。。我们认为，不可能将这一年代学扩大到更古老的年代，因为我们无法从古代建筑中获得任何样本。1.长白落叶松木炭年表的制作：在实验研究过程中，我们用木炭制作了379年的平均年表。在这项研究中，我们计划从长白山火山碎屑流的沉积物中采集更多的木炭样品。。但我们无法获得足够的样本，因为如果大洪水和中国与朝鲜交界处的政治问题。长白山落叶松发生的树轮格局，以及长白山水杉的年轮格局。来自青森前的岛下半岛，彼此通信。当我们可以做出公元700年的主年表时。Dhujopsis delabrata var.我们可以查一查木炭的树轮图案。因此，我们可以将年龄扩大到公元814年。在渤海现状的考古研究中，我们必须了解位于长白山脚下的广塔、宝马遗址、黑龙江胜金龙泉府遗址与日本同期遗址和发掘的结构之间的密切关系。

Making a master chronology using living Larix olgensis : Before starting this research , we could expand the average pattern (1836 - 1992 ) of Larix olgensis , which was made during the experimental research , to the age of 1804 using the core samples collected at the west foot of Changbai Mt. . We think that it will be impossible to expand this chronology to much older ages because we can't get any sample from the ancient architecture. .Making a master chronology using charcoal of larix olgensis : We made the average pattern of 379 years using charcoal during experimental research . Under this research we were palnning to collect much more samples of charcoal from the sediment of the pyroclastic flow in Changbai Mt. . But we couldn't get enough samples because if the big flood and the polotical problems at the boundary lines of China and North Korea.The tree ring pattern of Larix ogensis of Chang bai Mt, and that of Thujopsis dolabrata var. from Shimokita Peninsula of Aomori Pre, were corresponded each other . When we can make the master chronology of the age of 700 AD. Of Thujopsis delabrata var. we can check it up wish the tree ring patterns of charcoal . As the result we could expand the age 814 AD. , we must do continuous research collecting more samples .On archaeological research of Bo hai Quo we must know the close relations between Guang ta , Bao ma oid site which is located in the foot of Chang bai Mt., Hei long jiang sheng jin long quan fu site and the structure of the ruins and excavations at the same period in Japan .
