摘要
本文分析了鄂中丘陵地区一个典型农户生态系统的能流途径,人工辅助能的输入结构,各亚系统的能量输入、输出组成和能量流动关系,以及能量转化效率。以70个农户的样本分析研究了投能结构对能效的影响规律。结果表明,当地农户生态系统仍是一种以有机能为主要人工辅助的封闭性较强的能量转化系统;增加人工辅助能,特别是无机能的投入可以增加能量产出。
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.
