摘 要:以生态足迹模型为基础,引用了“国家公顷”生态足迹模型的概念,结合吉安市2009—2018年的耕地生态主要农作物和经济作物的年产量,占地面积和年均产量等指标,计算得出吉安市2009—2018年的10 a间人均耕地生态足迹增长了10.2%,人均耕地生态承载力仅增长不到1.4%,2013年后吉安市人均耕地生态赤字速度明显加快,其耕地可持续发展指数由弱可持续向弱不可持续发展,基于计算结果吉安市未来土地利用规划中需加强耕地保护,合理调整土地结构,减少耕地压力,实现耕地的可持续发展。Based on the ecological footprint model and the concept of"National Hectare"ecological footprint model,combined with the annual output,floor area and average annual output of cultivated land ecological main crops and cash crops in Ji'an City from 2009 to 2018,it is calculated that the per capita cultivated land ecological footprint in Ji'an city increased by 10.2%and the per capita cultivated land ecological carrying capacity increased by less than 1.4%in the 10 years from 2009 to 2018,After 2013,the ecological deficit of per capita cultivated land in Ji'an City has significantly accelerated,and its sustainable development index of cultivated land has changed from weak sustainability to weak unsustainability.Based on the calculation results,Ji'an city needs to strengthen cultivated land protection,reasonably adjust land structure,reduce cultivated land pressure and realize the sustainable development of cultivated land in its future land use planning.
