摘　　要：对四位一体北方能源生态模式的沼气发酵原料、沼气成分、沼液成分及沼渣成分进行了测试分析。结果表明,12月份测试时系统内温度较低,沼气发酵受到抑制,9月份温度较高,沼气发酵较活跃;沼液、沼渣中含有丰富的营养成分、重金属含量较少,沼液、沼渣是良好的有机肥。该研究为北方能源生态模式的发展提供了参考。Analyses of anaerobic fermentation material, biogas, fermented liquid and fermented residue of northern energy-ecology ecosystem were carried out. Results showed that anaerobic fermentation was restricted in December due to the reasons that the fermentation temperature was low, and that it was promoted in September because of high fermentation temperature. Fermented liquid and residue had a plentiful nutrients and a little heavy metal. They were a good organic fertilizer. The research has provided a reference for the development of northern energy-ecology ecosystem.
