摘　　要：利用生态足迹方法对1993—2010年延吉市人均生态足迹和人均生态承载力进行计算和分析,并利用灰色系统对其2011—2014年土地生态承载力状况进行动态预测。结果表明,延吉市处于生态超载、不可持续发展状态,至2014年人均生态赤字将达到1.522hm2/人。因此,需提出优化措施,以期适应延龙图一体化社会经济功能的特点,寻求在资源环境承载力范围内实现延吉市可持续发展的途径和对策。The ecological footprint and ecological capacity of Yanji from 1993 to 2010 was studied,the use of gray system to its ecological footprint for dynamic prediction . The results showed that Yanji City was beyond the capacity of the natural ecological system, which was in unsustainable development status, the average personal ecological deficit of Yanji would be 1. 522 hm2. Based on these,some suggestions were put forward to adapt to the social economy function characteristics integration in construction of Yanji- Longjing-Tumen Central Cities, seeking in resource environmental bearing capacity to realize ways and measures in the sustainable development of Yanji City.
