Abstract: The household ecosystem in the Anlu City of Hubei Province was Studied in the paper. The ways of energy flow, structure of auxiliary energy input, composition of the input and output enefgy for different sub-systems, and the relation of energy flow in different sub-systems and energy transform efficiency are analyzed in a typical household ecosystem. And the effect of auxiliary energy input composition on energy transformation efficiency was studied. The results show that household ecosystem in the hilly of the central Hubei Province is still a blockaded energy transformation system with organic energy as main auxiliary energy. The input of auxiliary energy, especially inorganic energy, can greatly increase energy transformation efficiency. 

Key words: household ecosystem, energy flow, auxiliary energy, organic energy, inorganic energy
