Combined heat and power (CHP) plants fueled by biomass can collect and utilize waste straw resources in a productive way. This paper considers the impact of regional factors on biomass energy potential and the energy needs of the population, so as to study the differences in construction of biomass CHP plants and the collection scope of raw materials, and proposes evaluating suitability for biomass energy development based on scope of resource collection. Taking five counties in China as its study areas, this paper assesses biomass energy potential. A topology system of biomass CHP plants has been reasonably established in different counties through ArcGIS, the required installed capacity has been calculated according to the number of persons served by such plants. Finally, the collection length and corresponding value range of raw materials of CHP plants along roads has been obtained based on biomass energy potential and energy demand. The result shows that the differences in area, straw yield and biomass fuelization rate depending on regions have a great impact on biomass energy potential, while the residue-to-product ratio of straw and biomass calorific value have less of an impact. When the biomass energy per capita of a region reaches 9.75GJ/person, it is suitable for biomass energy development. The installed capacity in the biomass CHP plant system of each study area is mostly within the scope of 3-59 MW, and the collection length of corresponding biomass resources of such plants along roads is mostly within the scope of 5.09-25.23 km.
生物质联合热电联产（CHP）厂可以以生产的方式收集和利用废秸秆资源。本文考虑了区域因素对生物质能源潜力和人口能源需求的影响，以研究生物质 CHP 厂建设和原材料收集范围的差异，并提出了基于资源收集范围评估生物质能源开发适宜性的方法。本文以中国的五个县为研究区域，评估了生物质能源潜力。通过 ArcGIS 合理建立了不同县生物质 CHP 厂的拓扑系统，根据这些厂服务的人数计算了所需的装机容量。最后，根据生物质能源潜力和能源需求，得到了 CHP 厂沿路原材料的收集长度和相应的价值范围。结果表明，地区差异、秸秆产量和生物质燃料化率对生物质能源潜力有很大影响，而秸秆的残物-产品比和生物质热值的影响较小。当一个地区的人均生物质能源达到 9.75GJ/人时，就适合生物质能源开发。每个研究区域生物质 CHP 厂系统的装机容量大多在 3-59MW 范围内，相应的生物质资源的收集长度大多在 5.09-25.23km 范围内。
