摘要
对三峡库区家庭农业生态系统中的各种物质、能量、货币在系统投入与产出的过程中进行了能值分析,对家庭农业生态系统及其亚系统能量的投入与产出进行了能值评价,通过能值指标分析了辅助能投入结构、辅助能投入比例以及家庭农业生态系统、种植亚系统和养殖亚系统的能值产投比,提出了家庭农业生态系统能流的调控措施.
The energy analysis of material, energy and currency with input and output in Three Gorges reservoir area courtyard agro-ecosystem is discussed in this paper.And the energy input and output in agro-ecosystem and subsystem are evaluated. The structure and proportion of auxiliary energy and the ratio of output/input in courtyard agro-ecosystem, planting and breeding subsystem were discussed with emergy indexes. The regulation and control measures of energy flow in courtyard agro-ecosystem are put forward.
