(1) Analytical methodology on allocation of inter-regional material transaction is proposed corresponding to the frame of material flow accounting. Inter-regional material flow was calculated using available statistical data.(2) Recycling systems of plastic waste which are liquefaction, pyrolysis gas combustion process etc. were evaluated from the viewpoint of recycling cost and energy efficiency.(3) Historical issues on timber production, for example low price timber imports and diminution of workers, were analyzed by KJ-method and ISM.(4) Modeling on stock of forest is proposed which simulate timber volume through planting and cutting. Appropriate cutting volume is calculated for sustainable development.(5) The methodology on soundly forest and blighted forest is proposed based on NDVI from Landsat/TM imagery.(6) The volume of timber based on detail specified data by GIS was estimated, and ability of supplying for local domestic energy by generation using wood resources or by stove using wood pellet was calculated.

(1)针对物质流量核算的框架，提出了区域间物质交易分配的分析方法。利用现有统计数据计算区域间物质流。(2)从回收成本和能源效率的角度评估液化、热解气体燃烧过程等塑料废物的回收系统。(3)木材生产的历史问题利用KJ法和ISM对低价木材进口和劳动力减少等问题进行了分析。(4)提出了森林蓄积量模型,通过种植和采伐来模拟木材蓄积量。计算出适合可持续发展的砍伐量。(5)基于Landsat/TM影像的NDVI，提出了健康森林和枯萎森林的方法。(6)根据GIS的详细指定数据估算了木材体积，并确定了森林的能力。计算了使用木材资源发电或使用木屑颗粒炉灶供应当地生活能源的比例。
