摘　　要：为探究郓城县种植业生产系统的可持续发展水平,采用能值分析法,分析了郓城县1978—2019年种植业生产系统可持续发展指数的变化趋势,并具体分析了可持续发展指数对能值投入的敏感性以及单位面积上不同作物的可持续发展指数。结果表明:1978—2019年,郓城县种植业生产系统可持续发展指数呈现先上升后下降趋势,其中,2002年可持续发展指数最低,为1.21;2019年可持续发展指数为1.29,接近指数1的警戒线。在投入敏感性方面,不可更新工业辅助能对可持续发展指数影响最为显著,不可更新工业辅助能每增加15%,可持续发展指数平均下降约7%。从单位面积上不同作物的可持续发展指数来看,大豆单位面积的可持续发展指数最高。基于以上结果,建议通过减少化肥的不合理使用、改善耕作措施、升级农机装备、加强种植基础设施建设、合理调整种植结构来提高郓城县种植业的可持续发展水平。In order to explore the sustainable development level of the planting production system in Yuncheng County,the emergy analysis method was used to analyze the change trend of the sustainable development index of the planting production system in Yuncheng County from 1978 to 2019,and the sensitivity of the sustainable index to the energy input and the sustainable index of different crops in unit area were specifically analyzed.The results showed that from 1978 to 2019,the sustainable development index of the planting production system in Yuncheng County showed a trend of first rising and then declining.The sustainable index in 2002 was the lowest,with a value of 1.21.The sustainable index in 2019 was 1.29,which was close to the warning line of index 1.In terms of input sensitivity,non renewable industrial auxiliary energy has the most significant impact on the sustainable development index.The non renewable industrial auxiliary energy increases by 15%,and the sustainable index decreases by about 7%on average.From the perspective of sustainability index of different crops per unit area,the sustainability index of soybean per unit area is the highest.Based on the above results,it is suggested to improve the sustainable development level of planting industry in Yuncheng County by reducing the unreasonable use of chemical fertilizer,improving farming measures,upgrading agricultural machinery and equipment,strengthening the construction of planting infrastructure,and reasonably adjusting the planting structure.
