Inter-regional material flow accounting and simulation model of timber production ability towards industrial ecology

(1)根据物流会计的框架，提出了区域间物资交易分配的分析方法。利用现有的统计数据计算区域间的物质流动。(2)从回收成本和能源效率的角度对塑料废弃物的液化、热解气燃烧等回收系统进行了评价。(3)采用kj法和ISM分析了木材生产的历史问题，如木材进口价格低、工人减少等。(4)提出了森林蓄积量模型，模拟了植树和采伐的木材量。为可持续发展计算合适的切削量。(5)提出了基于Landsat/TM影像NDVI的健全林和枯萎林的方法。(6)在GIS详细数据的基础上估算了当地木材的体积，并计算了利用木材资源发电或利用木屑颗粒的炉子为当地居民提供能源的能力。

(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.
