| Research Abstract |
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 .
