中文摘要：

农田生物质能具有能源密度低,不确定性程度大,分布分散的特点。以广东省为例,利用生物量模型对区域农田生物质能进行栅格尺度的估算,并结合实地调查数据,分析了区域农田生物质可集约利用为能源的各类影响因素,建立了农田生物质能的理论蕴藏量、可获得量、可集约利用量的决策模型。利用邻域分析法和移动窗口法对区域生物质能优势带分布和二级收集区进行分析,结果表明,广东农田生物质能分布优势带主要集中在雷州半岛地区、粤西南丘陵地区、潮汕平原区、粤东沿海丘陵台地等地区。广东省发展直接燃烧供热发电项目,原料供应有一定风险。可以采用固化燃料或气化、醇化成燃料乙醇等方式发展生物质能项目。

英文摘要：

Farmland biomass energy has some features such as low energy density,large uncertainty,and disperse distribution.Taking Guangdong Province as an example,this paper estimated farmland biomass energy quantity at grid scale by using the biomass model.Combining with field survey data,it analyzed the various factors that affect regional farmland biomass used for energy,and established the decision-making model used for estimating biomass energy theoretical potential,available quantities,and the amount of intensive use.Neighborhood analysis and moving window method were used to study the advantages of regional biomass distribution and two-level collection area.The results showed that the advantage zone of farmland biomass energy in Guangdong distributed in Leizhou Peninsula,southwest hilly region,Chaoshan Plains,eastern coastal hilly plateau etc.But there was a certain risk of supplying raw materials for direct combustion power generation in Guangdong province.Adopting curing fuel,gasification,purify fuel ethanol may be acceptable for the development of biomass energy intensively use.
