随着木质生物质的国际市场的出现，丹麦日益增长的能源木片消费导致进口增加。由于竞争力的提高和毫无疑问的环境效益，国内木片供应是可取的，但必须采取措施，使供应链更具成本效益。运输是木片交付成本的主要因素之一，这在很大程度上取决于森林和能源工厂的地理位置。本文提出了一种基于栅格地理信息系统（GIS）的连续成本曲面映射方法。全国木片资源已经绘制，并为选定的生物能源工厂的运输成本，每年的燃料需求已建模使用成本距离函数，供应曲线和敏感性分析。因此，建立了累积木片资源与其平均成本的地理决定关系。研究结果可用于社会经济合理的资源分配，最佳的植物燃料组合，规划未来的能源工厂。
While international markets for woody biomass emerge, growing consumption of wood chips for energy in Denmark is leading to increasing import. With improved competitiveness and unquestionable environmental benefits, domestic wood chip supply is preferable, but measures must be taken to make the supply chain more cost efficient. One of the major contributors to the delivered costs of wood chips is transportation, which is highly determined by the geographical location of forests and energy plants. This paper presents a method based on continuous cost surface mapping using raster-based geographical information systems (GISs). The national wood chip resources have been mapped and for selected bioenergy plants the costs of transporting the annual fuel demand have been modelled using cost distance functions, supply curves and sensitivity analysis. Hence a geographically determined relation of cumulative wood chip resources and their average costs was established. The results may be used for socio-economically sound resource allocation, optimal plant fuel mix, and planning of future energy plants.
