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.
Key words: ecological farm, energy-flow, artificial supplementary energy, ecological efficiency
