摘　　要：中国的城市化进程正处于高速发展期,部分区域为了解决村庄人口外流造成的农业衰落问题而执行了村庄合并规划。在村庄合并规划环节中重新审视生物质热电厂的规模与数量问题,有利于展开对生物质热电厂投资成本与能源利用效率的研究,进而优化能源消费结构,推进可持续发展进程。通过预测城市化比例确定撤销村庄,将撤销村庄人口重新分配至保留村庄内,同时在人口稀少的区域新建镇分流部分人口。通过对比村庄合并规划前分散建设15座生物质热电厂与村庄合并规划后集中建设1座生物质热电厂两种情况下的分析数据得出结论:生物质热电厂采用集中建设模式比分散建设模式的投资成本低6.29亿元,且每年可节约秸秆87930.31吨,折价为2198.26万元。China s urbanization process is rapidly developing.Thus,it is imperative to implement the village merger plan to address the decline in agriculture caused by the outflow of village populations.Re-evaluating the scale and quantity of biomass combined with heat and power(CHP)plants in the village merger planning process is beneficial for analyzing the investment costs and energy utilization ratios of biomass CHP plants and optimizing the energy consumption structure and promoting sustainable development processes.Predicting the extent of urbanization is useful in determining the abandonment of villages,where the populations are redistributed to other villages,while new towns are simultaneously built in sparsely populated northwestern areas for relocated portions of the population.By comparing the analyzed data of the construction of 15 biomass CHP plants before the village merger plan and the centralized construction of a biomass CHP plant after the village merger plan,the investment cost of a biomass CHP plant that adopts a centralized construction mode is determined to save 629 million RMB Yuan,compared with a plant adopting a decentralized construction mode.Additionally,87,930.31 tons of straw can be saved annually,which is equivalent to 21.92260 million Yuan.
