 note = {Although paleoenvironmental studies have been actively carried out all over the world, little has been known about the climatic and environmental changes especially in Eurasian continental interior relative to oceans and the land areas close to sea. In this context, we have been attempting to obtain such a paleoenvironmental information for the past 300,000 yrs recorded in a sediment core from Lake Baikal located in the interior, using various organic molecules. From results so far, it was revealed that the flora and precipitation around Lake Baikal and the primary production of the lake during the past 30,000 yrs changed with the following features : 1) Basically, the flora was tundra or desert grass in cold periods and taiga in warm periods. But, it was indicated that such a glass and taiga prevail for certain time period even during so-called warm and cold periods, respectively. 2) In general, precipitation is low in so-called cold periods, while it is high in warm periods. It was evident, however, that precipitation was sometimes considerably high in a cold period, whereas in a warm period, it was sometimes a little bit low. Despite such conditions, a high relationship was found between the changes of precipitation and flora around Lake Baikal, indicating that one of the major factors controlling the land flora is precipitation. 3) Based on the vertical distribution of plankton-derived sterol in the sediment core, the primary production of the lake was low in cold periods and high in warm periods. A high correlation between the primary production and precipitation was strongly suggested that precipitation determines the primary production of Lake Baikal through a transportation of nutrients from land., 第16回名古屋大学タンデトロン加速器質量分析計シンポジウム(平成15年(2003年度)報告 Proceedings of the 16th Symposium on Researches Using the Tandetron AMS System at Nagoya University in 2003 日時:平成16(2004)年1月22日(木)､23日(金) 会場:名古屋大学シンポジオン Date:January 22nd and 23rd,2004 Place:Nagoya University Symposion Hall},
