摘　　要：运用能值理论分析贵州民族自治地区农业生态经济系统的发展现状,选取环境负荷率、基于能值分析的可持续发展指数等9项评价指标构建能值分析指标体系,综合分析系统现状特征。结果表明:(1)农业生态经济系统能值主要来自于劳动力的可更新有机能,表明农业系统主要依赖的是大量劳动力的劳务输入;(2)农业生产过程中能值的转换效率较低,系统总的能值产出率及单位从业人员的能值生产率也远低于全国平均水平;(3)系统处于一个低水平的持续发展状态,需要提高农村劳动力的综合素质,对系统进行有意识的反馈,才能提高系统自组织能力,实现系统在一个较高水平上富有活力和健康的发展。Based on emergy analysis,this study carried out a detailed analysis for agricultural ecological-economic development of Guizhou ethnic autonomous areas, the indicators,such as environmental loading ratio, and emergy-based for sustainable index and so on were gotten.The results showed that：（1） Emergy of agricultural ecological-economic system could be updated from the renewable organic energy, that showed the agricultural system is mainly dependent on a large number of labor inputting. （2） The emergy conversion efficiency was low in the agricultural production process, and the emergy yield ratio and emergy productivity of the unit employees was far below the national average, too. （3） The system was in a low sustainable development level, which needed to improve the overall quality of the rural labor force in order to feedback to system, improving system self-organization ability to achieve a high level that full of vitality and health.
