This research project focused the changes in sediment flux linking with earth surface changes during recent 200 years in Pacific-rim Gee-systems. Totally 30 papers, four books and more than 10 proceedings concerning with this interest have been presented. Joint research programs with USA, New Zealand, Australia and China were also developed through this research project.The environmental factors such as geomorphologic structure, ecosystem, and landscape changes caused by human activities have studied from the view point of sediment production volume, sediment storage volume and sediment delivery volume expected. The actual observation for this project has been done in Oyabu catchment, Kyushu Island, Tenryu catchment, Nagano, and Saru Catchment, Hokkaido. In terms of comparing Japanese catchments with overseas catchment, Waiapu River basin, New Zealand, has additionally analyzed.Results are as follows.(1)Downstream change in fine particle sediment that reflected from earth surface changes were cleared (Kim et al.,2002 Kim et al.2003)(2)Relationship between catchment-scale geomorphology (catchment area, shape and drainage net) and patch-mosaic ecological tone such as forest and rural area using GIS was related with sediment production, storage and delivery (Ebisu et al.,2003 ; Itou et al., submitted).(3)Propagation and interaction between earth surface environment and sediment production, which has been successfully analyzed using the remote sensing system, were identified (Kikuchi,2003 ; Kunihuro et al.,2003 ; Mitsuda et al.,2003).(3)As a result the model developed in this study was applied to expect the sediment flux succeeding from 200 years changes in sedimentary system of Pacific-rim(Ebisu et al., submitted ; Kasai and Marutani,2004).

本研究主要研究环太平洋地区近200年来沉积物通量的变化与地表变化的关系。共提交了30篇关于这一兴趣的论文、4本书和10多个论文集。该研究项目还与美国、新西兰、澳大利亚和中国开展了联合研究项目，从产沙量、蓄沙量和预期输沙量的角度研究了人类活动引起的地貌结构、生态系统和景观变化等环境因素。该项目的实际观测已经在九州岛的大亚部流域、长野的天龙流域和北海道的Saru流域进行。在比较日本流域和国外流域的基础上，对新西兰怀阿普河流域进行了进一步的分析。结果表明：(1)从地表变化中反映出来的细颗粒泥沙在下游的变化(Kim等人，2002，Kim等人，2003)；(2)基于地理信息系统的流域尺度地貌(流域面积、形状和排水网)与森林和农村等斑块镶嵌生态基调的关系与泥沙的产生、储存和输送有关(EBisu等人，2003；(3)利用遥感系统成功地分析了地球表面环境和沉积物产生之间的传播和相互作用(Kikuchi，2003；Kunihuro等人，2003；Mitsuda等人，2003)。(3)因此，本研究中开发的模型被用于预测太平洋边缘沉积系统200年来变化后的沉积物通量(EBisu等人，提交；Kasai和Marutani，2004年)。
