Combined heat and power (CHP) generation can meet winter heating demands. Therefore, biomass CHP plants are more suitable for the development of biomass energy in village and town systems in cold regions. Transportation cost is one of the factors that determine operating costs. In this study, potential biomass energy is estimated based on the distribution of various types of crops. The locations and service areas of biomass CHP plants are determined using geographic information system analysis tools based on population distribution and energy demand data. Equations that contain multiple interference factors are used to calculate the raw material supply area and transportation cost for a biomass CHP plant to generate an optimal transportation route within a region. The analysis results show that biomass CHP plants are only suitable for village and town systems with a relatively low population density (PD). The curve of the supply area versus the PD of the village and town system (PD) has an inverse-S shape. The transportation cost increases exponentially as the PD increases. Biomass CHP plants can achieve higher efficiency in transportation costs when built in areas with a PD ≤ 65 people/km.
热电联产（CHP）可以满足冬季供暖需求。因此，生物质 CHP 工厂更适合在寒冷地区的村镇系统中发展生物质能源。运输成本是决定运营成本的因素之一。在本研究中，根据各种作物的分布估算了潜在的生物质能。基于人口分布和能源需求数据，使用地理信息系统分析工具确定生物质 CHP 工厂的位置和服务区。使用包含多个干扰因素的方程来计算生物质 CHP 厂的原料供应区域和运输成本，以在区域内生成最佳运输路线。分析结果表明，生物质 CHP 工厂仅适用于人口密度（PD）相对较低的村镇系统。供应区域与村镇系统 PD 的关系曲线呈反 S 形。随着 PD 的增加，运输成本呈指数级增长。当 PD≤65 人/km 时，生物质 CHP 厂在运输成本方面可以实现更高的效率。
