| 摘 要： | 应用系统能量学和热力学方法对户用能源生态工程北方模式的能量转化进行试验研究，通过系统模拟技术建立构成该模式的3个子系统的能量平衡方程。研究表明，日光温室种植子系统、畜圈饲养子系统和沼气池厌氧发酵子系统能量输出分别占总能量输出的21％，47％和32％，能量转化率分别达到1．37％、64％和84％，辅助能转化率为65％。该系统能量转化机制合理，是适合在中国北方农村地区推广的生态工程。

| Abstract: | The energy transition mechanism of the system was studied by system emergetics and thunnodynamics. The rural ecological engineering system consisted of 3 subsystems, of which were greenhouse, livestock barn and biogas digester. Energy balance equations for each of the subsystems were established according to systemic simulation technique. The results showed that the percentages of energy output from subsystems of ouse, livestock barn and biogas digester were 21%, 47% and 32%, and the rates of energy transition were 1.37%, 64% and 84%, respectively. The auxiliary energy transition rate was up to 65 %. The mechanism of energy transition in the ecological engineering was reasonable and should be extended in rural area of north of China. |
