摘要: 运用能值分析的理论和方法,通过构建能值分析指标体系,对桂林市2014—2019年农业生态经济系统的能值投入产出情况、环境承载情况以及可持续发展状况进行分析评价。结果表明,2014—2019年,桂林市农业生态经济系统总能值投入波动不大,辅助能值投入呈现先上升后下降趋势,在可更新辅助能值投入中,劳动力能值占94.46%。能值产出中,种植业所占比重最高,其次为畜牧业和林业。能值投资率持续处在较低水平;净能值产出率在2014—2017年逐年递增,2018年开始递减,维持在较高水平;环境负载率较低,环境压力小,系统富有活力和发展潜力。

Abstract: Based on the theory and method of emergy analysis, the emergy input-output, environmental carrying capacity and sustainable development of agricultural eco-economic system in Guilin city were analyzed and evaluated by constructing emergy analysis index system. The results showed that the total emergy input of agricultural eco-economic system fluctuated little in Guilin city from 2014 to 2019, and the auxiliary emergy input showed a downward trend after rising. In the renewable auxiliary emergy input, the labor emergy accounted for 94.46%. In emergy output, planting industry accounted for the highest proportion, followed by animal husbandry and forestry. Emergy investment rate remained at a low level; The net emergy output rate increased year by year from 2014 to 2017, and began to decrease in 2018, which remained at a high level; The environmental load rate was low, the environmental pressure was small, and the system was full of vitality and development potential.

Key words: emergy analysis, agricultural eco-economic system, sustainable development, Guilin city, environmental resources
