摘要
为摸清大兴区沼气资源、因地制宜地发展沼气业,根据大兴区2006年畜禽养殖的相关统计数据以及畜禽粪便产气系数获取各行政村的沼气潜能,结合G IS实现沼气潜能空间分布的可视化表达。在此基础上,结合国家发展新能源的相关政策以及当地的城乡规划方针,借助G IS强大的空间分析能力,进行了大中小型沼气工程以及小型粪污治理工程建设及具体的选址研究,并给出合适的备选区域。结果表明:以产气规模分析,大兴区有128个行政村适合建设大中型沼气工程,199个行政村适合建设小型沼气工程,204个行政村适合建设小型粪污治理工程;以最佳区域分析,大兴区共有36处区域最适合大中小型沼气工程及小型粪污治理工程建设。
In order to develop the local biogas industry, biogas resources and gas production potential were investigated for Daxing county. And the statistic results was realized visual expression of biogas distribution by GIS system( geographic information system) based on the animal data in Daxing colmty in 2006. And the location selection of biogas project was also studied with the aid of spatial analyzing ability of GIS system. The GIS graphs showed the suitable candidate regions for large and medium, or small biogas project. The results indicated 128 administrative villages suitable for the large and medium biogas project, and 199 suitable for small biagas project.
