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

(1)提出了与物流核算框架相对应的区际物资交易分配分析方法。利用现有统计数据计算了区域间物质流动。(2)从回收成本和能源效率的角度对液化法、热解气燃烧法等废旧塑料回收系统进行了评价。(3)运用KJ方法和ISM分析了木材生产的历史问题，如低价进口木材和工人减少。(4)建立了森林蓄积量模型，模拟了人工造林和采伐的蓄积量。计算出适宜的采伐量，以保证可持续发展。(5)提出了基于Landsat/TM影像的NDVI的森林完好林和枯损林的分类方法。(6)利用GIS技术，以详细的数据为基础，估算了木材的蓄积量，并计算了利用木材资源发电和利用木屑颗粒炉灶对当地生活能源的供应能力。

(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.
