摘要

Based on introducing the general situation of study area, a quantitative analysis of input-output status and sustainable development status of agro-ecosystem in Northern Anhui was conducted by using the method of ecological emergy analysis in this paper. The results show that the sustainable development ability of agro-ecosystem in Northern Anhui was in a middle level compared with its neighboring provinces and cities. Based on the results of emergy analysis, the countermeasures to improve the sustainable development ability of agro-ecosystem in Northern Anhui were put forward correspondingly, including reducing the input of non-renewable resources increasing utilization efficiency of non-renewable resources, developing ecological agriculture and so on.
