Response of land ecosystem to global environmental changes

本研究项目是在蒙布usho项目与TEMA（包括TEMA）的优先领域的科学研究密切联系的基础上进行的，GCTE的核心研究。结果汇总如下：西伯利亚泰加在Yakutski）真菌的特殊分布在水循环条件下. ii）光电合成活动和树叶水潜能在每个月内都被测量了水压力条件下的重要性. iii）土壤水分、树叶生理学的重要性。光合成特性和水的使用效率被证明是关于西伯利亚泰加森林的迁移模式的。DOC及其三个dimensional fluorescent property （EEM）在贝加尔湖和在巴尔古津河下进行了调查。这是我建议的，因为四个水的身体在贝加尔湖上都被发现了。The relative concentration of allochthonous DOC to total DOC was calculated for the lake waters。Lake Hovsgol in Mongoliai） Some biological and chemical Management teristics were measured and summarizedii） Recent rise in water level is found。NイD22イD2OIntramolecular distributions ofイD115イD1N andイD118イD1O were measured for dissolved NイD22イD2O in Lake Baikal and Bang Nara River in Tropical Thailand。

This research project is conducted in close connection to the Monbusho project for Scientific Research of Priority Areas that comprises TEMA, core research of GCTE. Results are summarized as follows.Siberian Taiga at Yakutski) Special distribution of vegetation was clarified in terms of water circulation.ii) Diurnal changes in photosynthetic activity and leaf water potential were measured every month in terms of water stress.iii) The importance of soil moisture, leafing phenslogy, photosynthetic characteristics and water use efficiency was demonstrated on the vegetation pattern of Siberian Taiga forest.Lake BaikalConcentration of DOC and its three-dimensional fluorescent property (EEM) were investigated in Lake Baikal and inflowing Barguzin River. It was suggested that four water bodies were distinguished in Lake Baikal. The relative concentration of allochthonous DOC to total DOC was calculated for the lake waters.Lake Hovsgol in Mongoliai) Some biological and chemical characteristics were measured and summarizedii) Recent rise in water level is found.NィイD22ィエD2OIntramolecular distributions of ィイD115ィエD1N and ィイD118ィエD1O were measured for dissolved NィイD22ィエD2O in Lake Baikal and Bang Nara River in Tropical Thailand.
