摘　　要：本文利用能值分析理论,定量分析了河南省农业生态经济系统可持续性的运行特征。研究结果表明:河南省农业生态系统能值产投效率相对较高,具有较强农业发展优势,环境承受能力和可持续发展能力较强,整体运营状况较好。目前,河南省农业农业生产模式无法摆脱石油农业的限制,且随着农业现代化建设的不断推进,不可更新工业辅助能投入急剧增加,必将对其农业发展可持续性产生较大的压力。This paper analyzes the operating characteristics and sustainability of agroecosystem in Henan Province by structuring index system based on energy analysis.The results by quantitative calculation show that the agroecosystem in Henan Province has higher efficiency of energy output,strong market competition capacity,powerful environmental carrying capacity and sustainable development capacity,and operates well as a whole.However,the unrenewable industrial energy in Henan agroecosystem rising at a big range and its agricultural produce model couldn't break away from the limit of petroleum agriculture,which leads to its sustainability trend decreasing at a certain degree and great pressure on its ecological environment.
