摘　　要：沼气综合利用是农村沼气建设中降低生产成本、提高经济效益的一项综合性技术措施,本文以我国2004年的沼气综合利用情况,分析了沼气综合利用的生态经济效益,在此基础上对中国沼气综合利用潜力进行估算。结果表明,中国沼气综合利用生态经济效益显著,2004年沼气综合利用增加经济效益43.57×108元,保护森林167.1×104hm2,减少CO2排放655.17×104t,减少SO2排放5.94×104t。目前中国沼气发酵产物综合利用程度较低,经济潜力开发率不到1%,生态潜力开发率仅在4%左右,前景广阔。Biogas comprehensive utilization is significant to improving the rural ecological environment, raising farmer＇s income and realizing sustainable development. This article introduced the current situation of biogas comprehensive utilization in China, analyzed the economic and ecological benefits, and estimated the potentiality of biogas comprehensive utilization. The results showed that the biogas comprehensive utilization has remarkable economic and ecological benefits in China. It increased income by 4.36 billion yuan（RMB） in 2004, protected 1.67 million hectares forest, and reduced 6. 55 million tons of CO2 and 59.4 thousand tons of SO2. However, the application rate of anaerobic fermentation of rural waste is still low. The exploiture rate of biogas economic potential is less than 1% and that of ecological potentiality is about 4%, the prospect of biogas comprehensive utilization in China is bread.
