This research was organized to establish the monitoring systems and stations in tropical rainforest ecosystems, to contribute to a core-research program "Global change impact on terrestrial ecosystems in Monsoon Asia "(TEMA) of IGBP-GCTE.TEMA monitoring network across East-Asian forest belt is accomplished by the establishment of lowland tropical rainforest sites in Borneo Island. This research was carried out under the collaboration with Indonesian and Malaysian counterparts' full support.One site in Central Kalimantan, Indonesian Borneo, was characterized by regionally nutrient poor systems, i.e.heath forest and peat-swamp forest. We established four permanent plots and one research hut on these ecosystems in Lahei site, 20-km NE from PalangkaRaya, where we carried out tree census and set litter traps and litter bags. Monitoring of the emission of greenhouse gasses was regularly carried out. To examine a lager-area characteristics of terrestrial ecosystems, preliminary land water survey was also conducted.For coastal ecosystems, research station was established in Tabin National Park in Sabah, Malaysian Borneo, and high-altitude forest systems were monitored in Mount Kinabalu National Park in Sabah.One symposium held in Sapporo early in February covered present activities in relation to TEMA,and four members participated in the GCTE-LUCC Conference in Barcelona in mid March, reporting the present activities.

本研究旨在建立热带雨林生态系统的监测系统和监测站，为IGBP-GCTE的核心研究项目“全球变化对亚洲季风区陆地生态系统的影响“（特马）做出贡献。通过在婆罗洲岛建立低地热带雨林监测点，完成了东亚森林带的特马监测网络。这项研究是在印度尼西亚和马来西亚同行的全力支持下进行的。印度尼西亚婆罗洲加里曼丹中部的一个地点具有区域性营养贫乏系统的特点，即石南林和泥炭沼泽林。我们在距离PalangkaRaya东北20公里的Lahei现场建立了四个永久性地块和一个研究小屋，在那里我们进行了树木普查，并设置了垃圾陷阱和垃圾袋。定期对温室气体排放进行监测。为了研究陆地生态系统的大面积特征，还进行了初步的陆地水调查。对于海岸生态系统，在马来西亚婆罗洲沙巴州的塔宾国家公园建立了研究站，并在沙巴的京那巴鲁山国家公园监测了高海拔森林系统。2月初在札幌举行的一次研讨会讨论了与特马有关的目前活动，四名成员参加了3月中旬在巴塞罗那举行的GCTE-LUCC会议，报告了目前的活动。
