摘　　要：土地生态安全评价是当前土地生态安全研究的热点之一,但已有的研究多以行政区划为基本单元,研究尺度涉及省级以及市县级,较少涉及城市圈的土地生态安全问题。以武汉城市圈为研究对象,基于PSR模型框架体系构建了武汉城市圈土地生态安全评价指标体系,并利用熵权灰色关联法分析了该区域2000年—2012年的土地生态安全变化状况。结果表明,武汉城市圈的土地生态安全呈现先恶化后好转的趋势,2009年—2012年处于临界安全状态;研究区土地生态系统对状态子系统和压力子系统的依赖程度较高,在调控时,应该积极关这两个子系统下各因子的变化和作用。Evaluation of land ecological security is one of the research hotspots in ecological safety,but the majority of previous research was based on the administrative division,the research scale involved provincial level and city or county level,and the metropolitan region level was little involved. Taking Wuhan Metropolitan Region as an example,this paper established an evaluation index system of land ecological security of Wuhan Metropolitan Region based on pressure-state-response（ PSR） model framework system,and analyzed the dynamic of and ecological security of Wuhan Metropolitan Region by using entropy-weighted gray correlation model. The results indicated that the land ecological security of Wuhan Metropolitan Region got worse first and then better from 2000 to 2012,and it was still in critical condition in at present. The safety status of general system is highly dependent on the status subsystem and pressure subsystem,so it is essential to regulate selectively the subsystems and the general system.
