In order to elucidate the enviromnental change mechanism in the Earth system, we carried out this research by combining satellite remote sensing and Earth system models with a focus on the interactions between the biosphere and climate. We developed a simple Earth system model which couples energy and carbon cycles in the atmosphere-ocean interactive system, and found that the oscillation occurs when the partial pressure of carbon dioxide in the deep ocean is smaller than that of the atmosphere. We also developed a meridional one-dimensional Earth system model of a coupled energy and carbon cycles, and investigated the effect of global warming to carbon uptake by the terrestrial biosphere : The global net ecosystem production(NEP)is greatly affected not only by the biosphere carbon dioxide fertilization and temperature dependency of soil decomposition but also by temperature dependency of net primary production(NPP)and soil decomposition rate. We developed a new terrestrial ecosystem model named BEAMS, and analyzed the global NPP variations since 1980's by using satellite observation data as input.We investigated the effect of the Himalaya-Tibetan Plateau(HT)on the onset of Asian monsoon with the coupled ocean-atmosphere General Circulation Model(GCM), and found that the existence of HT is an important condition to form the sub-tropical high atmospheric pressure zone of the northern hemisphere in summer. Interaction between the spatial and temporal variations of terrestrial vegetation and climate since 1980's was studied by using satellite remote sensing. We found that El Nino gives a negative impact to all types of the terrestrial vegetation mainly due to precipitation decrease, and there are time lag between El Nino and the terrestrial vegetation activities.

为了阐明地球系统中的环境变化机制，我们通过将卫星遥感和地球系统模型与生物圈与气候之间的相互作用相结合，进行了这项研究。我们开发了一个简单的地球系统模型，该模型将能量和碳循环融合在大气 - 海洋交互式系统中，并发现当深海中二氧化碳的部分压力小于大气的二氧化碳的部分压力时，振荡就会发生。我们还开发了一个耦合能量和碳周期的子午一维地球系统模型，并研究了陆地生物圈对全球变暖对碳吸收的影响：全球净生态系统生产（NEP）不仅受到生物二氧化物二氧化碳的依赖性和土壤依赖性的生产率的影响，而且还受到了土壤依赖性的生产率和净温度的生产率不仅受到较大的影响。我们开发了一种名为Beams的新的陆地生态系统模型，并通过使用卫星观察数据作为输入来分析自1980年以来的全球NPP变化。我们研究了喜马拉雅 - 藏族高原（HT）对亚洲季风开始的效果，并与couplate sepripitial IS的IS综合循环（gcm）的形式（gcm）的形式（gcm）的形式（gcm）的形式（发现）夏季，北半球的大气压力区。自1980年代以来，陆地植被与气候的空间和时间变化之间的相互作用是通过使用卫星遥感来研究的。我们发现，埃尔尼诺（El Nino）对所有类型的陆地植被产生负面影响，这主要是由于降水量减少，并且El Nino与陆地植被活动之间存在时间滞后。
