摘　　要：构建基于可持续发展三维度框架的城市土地生态安全综合评价指标体系,运用灰色关联投影模型和障碍度模型,对2004、2009和2014年武汉市土地生态安全动态变化特征及主要障碍因子进行分析。结果表明:(1)2004—2014年武汉市土地生态安全总水平缓慢提升,但安全层次不高,安全等级较低,土地生态安全系统的内部协调性逐渐降低;(2)土地生态安全单项水平中,环境子系统始终处于缓慢提升阶段,经济子系统由快速提升跌入缓慢提升阶段,社会子系统则从缓慢退化跃升至缓慢提升阶段;(3)武汉市土地生态安全水平的障碍因子类别、障碍度及因子排序始终处于动态变化之中,障碍因子经历了从经济类因素向资源环境类因素的转变过程。This paper has conducted an analysis of the dynamic change of land ecological security and main obstacle factors of Wuhan in the year of2004,2009and2014,through building urban land assessment index system based on reliance for the three-dimensional framework of sustainable development,as well as by using gray relation projection model and obstacle model.The results showed as follows.First,the land ecological security was improved slowly,while internal coordination of land ecological security system was lowered gradually with low security grade.Second,in the land ecological security system,environment subsystem remained slowly improving all the time,economic sub-system fell into slowly from improving sharply and fast,and social subsystems jumped from slowly lowering to slow improvement.Third,obstacle factor category,obstacle degree and ordering of factors with regard to land ecological security of Wuhan were in dynamic change,the obstacle factors experienced the transition from economic to resource and environment factors.
