GIS在生物质能源研究中的应用

生物质资源分布广阔而分散，且与环境、气候、土壤、土地利用等关系密切.地理信息系统(geographic information systems,GIS)具有空间数据分析功能以及易于与其他应用模型和算法相结合等特性，使其在生物质能源研究中具有优势.本文系统总结了国内外学者在生物质能源GIS应用方面的研究，着重讨论了GIS在生物质能开发可行性、生物质资源量及分布评估、生物质开发利用布局、生物质燃烧气体排放评估以及生物质能源信息系统等方面的应用，进而提出了GIS在生物质能源方面应用的3个趋势，即丰富数据源、提升数据处理和决策支持能力以及方案在线生成.

Applications of GIS in biomass energy source research

Biomass resources have the characteristics of widespread and dispersed distribution, which have close relations to the environment, climate, soil, and land use, etc. Geographic information system (GIS) has the functions of spatial analysis and the flexibility of integrating with other application models and algorithms, being of predominance to the biomass energy source research. This paper summarized the researches on the GIS applications in biomass energy source research, with the focus in the feasibility study of bioenergy development, assessment of biomass resources amount and distribution, layout of biomass exploitation and utilization, evaluation of gaseous emission from biomass burning, and biomass energy information system. Three perspectives of GIS applications in biomass energy source research were proposed, i.e., to enrich the data source, to improve the capacity on data processing and decision-support, and to generate the online proposal.
