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.

该研究项目与Monbusho优先领域科学研究项目密切相关，该项目包括GCTE的核心研究特马。结果总结如下。雅库茨克的西伯利亚针叶林）从水循环的角度阐明了植被的特殊分布。ii）在水分胁迫下每月测量光合活性和叶水势的日变化。iii）土壤水分、叶物候、光合特性和水分利用效率的研究表明，在西伯利亚针叶林的植被格局。研究了贝加尔湖和入湖巴尔古津河水体中DOC的含量及其三维荧光特性。有人认为，贝加尔湖有四个水体。对蒙古呼斯果尔湖溶解态N_（22）D_（20）D_（22）D
