本文基于能值生态足迹法(Emergy Ecological Footprint,EEF)对日照市单位面积耕地的利用的可持续性进行研究。结果表明:在研究时段内,日照市单位面积耕地的能值生态承载力一直处于较低水平,且变化不大;能值生态足迹总体增长;生态赤字总体增大,但近两年有下降趋势;对可持续发展指数变化的研究结果表明,日照市耕地利用的可持续性先降低,近年来又有所升高。为了实现日照市耕地可持续发展,应进一步保护耕地资源,提高耕地质量,加强农业基础设施建设,优化农业生态环境,合理控制人口增长,提高单位面积粮食产量。
本文基于能值生態足跡法(Emergy Ecological Footprint,EEF)對日照市單位麵積耕地的利用的可持續性進行研究。結果錶明:在研究時段內,日照市單位麵積耕地的能值生態承載力一直處于較低水平,且變化不大;能值生態足跡總體增長;生態赤字總體增大,但近兩年有下降趨勢;對可持續髮展指數變化的研究結果錶明,日照市耕地利用的可持續性先降低,近年來又有所升高。為瞭實現日照市耕地可持續髮展,應進一步保護耕地資源,提高耕地質量,加彊農業基礎設施建設,優化農業生態環境,閤理控製人口增長,提高單位麵積糧食產量。

Based on emergy ecological footprint,the farmland use sustainability of Rizhao City was stud-ied.The results showed that,during the study period,the farmland emergy carrying capacity per unit area had been in a low level with no obvious changes;the farmland emergy ecological footprint generally increased;the ecological deficit generally increased but showed decreasing trend in recent two years.The analysis of sustain-ability index showed that the farmland use sustainability decreased at first but increased in recent years. Therefore,in order to achieve the farmland sustainable development in Rizhao City,the farmland resources should be further protected,the farmland quality,infrastructure construction,agroecological environment and grain yield per area should be improved and the population increase should be rationally controlled.
