摘　　要：在介绍研究区域概况的基础上,应用生态能值分析方法对宿州市农业生态系统的投入产出状况、可持续发展状况进行了定量分析。结果表明,与周边省市相比较,宿州市农业生态可持续发展能力居于中游水平。依据能值分析的结果,提出了减少不可更新资源的投入、提高不可更新资源的利用效率、发展生态农业等提高宿州市农业生态系统可持续发展能力的对策。Based on introducing the general situation of study area,a quantitative analysis about input-output conditions and the sustainable development conditions of agricultural ecology in Suzhou City was carried out by using the method of ecological emergy analysis. The results showed that compared with its neighboring provinces and cities,the sustainable development ability of agricultural ecology of Suzhou City is in a middle level. Based on the results of emergy analysis,some countermeasures were put forward,such as reducing non-renewable resources inputs,increasing non-renewable resources use efficiency,developing ecological agriculture and so on.
