山区农村沼气发展中核心问题调查与研究

为了全面了解山区农村沼气发展现状及存在的突出问题，对商洛市2003—2010年建设的户用沼气、小型沼气工程、大中型沼气工程、服务网点的建设情况、使用情况、项目效益进行了调查。结果表明，户用沼气使用率为67.73%，其中以粪便为主要原料的占91.67%；沼肥施用率为78.52%，73.1%建池农户对沼气综合评价为好；养殖小区和联户沼气正常使用率为67.5%，大型沼气工程投入使用率83.33%，沼渣、沼液有效利用的占50%；乡村服务网点基本无运营收入。通过分析得出，山区沼气建设中存在的主要问题是户用沼气使用率低、小型沼气工程建设不规范集中供气难度大、大型养殖场沼气工程问题突出、后续服务跟不上网点难以运行、“三沼”的利用效率低，提出了加大宣传力度、加大资金投入、加强体系建设、规范养殖场沼气项目建设、强化政策保障五条促进沼气事业健康发展的对策。

Investigation and Study of Rural Biogas Development in Core

For a comprehensive understanding of rural biogas development status and issues, our household biogas for 2003-2010 in Shangluo construction, small-scale biogas projects, large and middle scale biogas engineering, construction, usage of the service network, project efficiency was investigated. Results showed that household biogas utilization as a 67.73%, to faeces as the main raw materials and 91.67%; defends 78.52%,73.1% pool farmer biogas fertilizer rates on comprehensive evaluation of biogas as well; farming community biogas normal usage for 67.5% and lianhu, large investment in biogas engineering usage 83.33%, biogas residue, effective utilization of biogas; 50% rural service network basic non-operating income. Through analysis came, mountain biogas construction in the exists of main is households with biogas using rate low, and small biogas engineering construction not specification concentrated gas supply difficulty large, and large farm biogas engineering problem highlight, and follow-up service with not Shang dot difficult to run, and "three biogas" of using efficiency low, made has increased publicity intensity, and increased funds inputs, and strengthening system construction, and specification farm biogas project construction, and strengthening policy protection five article promote biogas career health development of countermeasures.
