文章运用能值理论分析方法,对黑龙江省农垦北安局2001年-2008年农业生态经济系统发展现状进行研究分析。研究结果表明,系统能值投入和产出呈逐年增长的趋势,能值自给率、人口承载力和净能值产出率呈下降趋势,能值投资率、人均能值使用量和能值密度呈增加态势,环境压力逐年增加。根据能值指标分析结果和经济发展现状,提出农业生态系统可持续发展对策。

This paper studied and analyzed the development status of agricultural eco-economic system in Beian Reclamation Bureau,Heilongjiang Province from 2001 to 2008 by applying the theory of emergy analysis.Results show that the emergy input and output of the system grows year by year.The emergy self-sufficiency ratio,the population carrying capacity and the net emergy yield ratio descends.The emergy investment ratio,the emergy per person,the emergy per area,and the pressure on the environment increases.According to these results and present economic development situation of this area,some countermeasures to deal with the sustainable development of agro-ecosystems were proposed.
