摘要:
土地生态安全评价是生态安全评价的的重要组成部分，也是当前土地可持续利用研究的前沿课题，对其进行研究有着极其重要的意义。利用2001-2007年的相关数据，借助于物元模型对鄱阳湖生态经济区的土地生态安全进行研究。结果表明：（1）鄱阳湖生态经济区土地生态安全状况，由2001年较安全状态下降到2005不安全状态。（2）2005-2007年土地生态安全由不安全状态到临界安全状态，状态有所好转。研究也证明了利用物元模型进行区域土地生态安全评价是可行的，这种方法可作为土地生态安全评价研究的新方法。
Abstract:
The land ecological security evaluation is the important component of the ecological security evaluation, is also the current land sustainable use research forefront topic, and it is vitally significant to research. The purpose of this paper is to use relevant data from 2001 to 2007 to study the land ecological security in Poyang Lake ecological economic zone by employing matter-element model. The results show that: (1) the land ecological security state in Poyang Lake ecological economic zone had been dropped from 2001 to 2005; (2) from 2005 to 2007, the land ecological security state had been improved, from the unsafe condition to the critically safe condition. The result of the research has proved that it is feasible to evaluate regional land ecological security by using matter-element model, and this method can be used as land ecological security evaluation research new method.
