文章运用能值分析法对霍林河下游生态经济系统的能值投入产出、净能值产出率与投入率、人均能值用量和环境承载率进行了计算;以净能值产出率与环境承载率的比值作为能值可持续性发展指数(ESI),在建立能值可持续性分级基准的基础上,定量研究了生态经济系统的可持续发展能力。结果表明,研究区生态经济系统的能值总投入为9.15×1021sej,以不可更新的工业辅助能值为主;总产出为10.61×1021sej,以种植业和畜牧业为主。全区平均ESI为0.17处于不可持续范畴,针对该区实际情况和能值分析结果,提出调整能值投入结构、提高农业生态环境承载力等使生态经济系统可持续发展的对策。
In this paper, emergy input-output, net energy yield and input rate, per capita energy consumption and environmental carrying capacity are calculated by using emergy analysis method. The net output value And the ratio of environmental carrying capacity as the sustainability index (ESI) of sustainable development, the sustainable development capability of eco-economic system was quantitatively studied on the basis of establishing the sustainable classification index of sustainable energy. The results show that the total energy emergy input of the eco-economic system in the study area is 9.15 × 1021sej, with non-renewable industrial auxiliary emergy as the main output; the total output is 10.61 × 1021sej, mainly planting and livestock husbandry. According to the actual situation and emergy analysis results of the area, some suggestions are put forward, such as adjusting the structure of emergy input, increasing the bearing capacity of agro-ecological environment and making the eco-economic system sustainable development.
