密云库北林木废弃物生物质气化站资源量分析及收集半径计量

摘要:本文针对北京水源地密云库北区域生物质能源利用的原料供应问题，采用实地调研、模型核算及投资项目投资估算的方法，以西庄子生物质气化站为典型案例，核算了该生物质气化站以果园林木废弃物为原料的平均资源收集半径为5.6公里，以及考虑收集费用等经济约束条件下合理资源收集半径为6.4，并据此，提出库北三镇的应建设林木废弃物生物质气化站的合理数量，为政府部门提供决策服务。

Resources Analysis of biomass stations in the North of Miyun Reservoir and Measurment of the collecting Radium

Forest biomass energy is important in Beijing suburb,especially in Miyun water protection areas.This article was to solve the material problems of forest biomass station in the north of Miyun Reservoir.Method of field survey,modeling accounting and estimating for investment were adopted and used the Xizhuangzi biomass station as a case study.The result showed that the average resource collecting semidiameter of this biomass station was 1.13 km by the resources of all the eco-forests,and 5.6 km by the resources of all the orchards.At the same time,the average rational collecting semidiameter was 6.4 km if considering the collecting expenses.According to this conclusion,3 biomass stations should be constructed in the north part of Miyun water protection areas.
