| 摘 要： | 本文详细分析了康集生态农场建设初期的能流结构及生态效率。结果表明，经过５年的开发，康集生态农场已初步建成具有较复杂的网络式能流系统。系统的能量利用与转化效率逐年提高，其中种植业和家畜家禽饲养业的能量利用率较高，而养鱼业的能量转化率低，在能量利用上潜力极大。第二性生产的绝大部分人工辅助能依靠系统外输入。据此提出了提高康集生态农场能量利用效率的调控措施。

| Abstract: | Detailed analysis of the energy-flow structure and ecological efficiency was conducted based on the energy input and output in Kangji Ecological Farm, Chengwu County of Shandong Province. The results show that the farm has established a complex energy-flow network system within five years. Within the system, the conversion efficiency of energy have increased year by year. The output and input ratios of artificial supplementary energy in plantation, poultry and stock-raising are higher than that in fishery. In the secondary production, the great quantity of artificial supplementary energy depends on external input. Based on the potentials of energy utilization and the state of energy flow, measures for raising energy conversion efficiency have been put forward. |
