能值分析是指通过能值相关理论及原理的分析得出一系列反映农业生态经济系统的能值指标体系,借此可深入分析系统的环境容纳能力、能值效率、生态经济效益,系统结构功能特征及可持续发展能力,对更好的发展农村解决有重要意义.文章通过对相关文献的梳理和归纳,从可持续发展角度探讨国内农村生态系统能值发展状况,研究我国农业生态系统的能值投入,针对国内农业生态经济进步的现状客观评价该系统可持续发展状况.结果表明:当前农业生态发展迅速,但就农业生态经济系统的能值研究方面,在资料收集、理论不足等方面依然需要改进.并提出严控人口数量、科学开发后续土地资源、改善土地运用构成、增强可更新环境资源运用效率等对策与建议,以期能为政府决策提供科学依据,助力于社会经济的全方位进步及农业的有效转型.%The emergy analysis refersa series of agricultural eco economic system emergy index system,which can reflect the environmental capacity,energy efficiency,ecological and economic benefits,the structure and function of system features and the ability of sustainable development.Using theemergy analysis theory,based on the literature review,this paper analyzed the agricultural ecological system in China and the current domestic agricultural eco -economic progress,and evaluated the sustainable development status.It concluded that the current agricultural ecological development was rapid,but it still needed to be improved in the aspects of data collection and theoretical issues of the agricultural eco-economic system.Finally,the article put forward the corresponding countermeasures and suggestions to provide a scientific basis for government decision-making and help the all-round progress of the social economy and the effective transformation of agriculture.
