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.

该研究项目是与Monbusho项目密切相关的，用于构成Tema的优先领域的科学研究，包括GCTE的核心研究。结果汇总如下。雅库茨基的西伯利亚taiga在水流通方面进行了特殊分布。II）光合作用活性和叶水潜力的昼夜变化每月都在水压力下衡量。IIII）在水分压力上。在贝加尔湖和流入的Barguzin河中研究了DOC及其三维荧光特性（EEM）的贝卡尔浓度。有人建议在贝加尔湖区分开四个水体。计算了针对湖水的相对浓度与总DOC的相对浓度。 NII D22 O在泰国热带泰国湖和Bang Nara河中。
