摘    要:基于2001-2007年的相关数据,借助物元模型对鄱阳湖生态经济区的土地生态安全状况进行研究.结果表明:2001年鄱阳湖生态经济区土地生态安全状况为较安全状态,2002—2004年处于临界安全状态,2005年下降为不安全状态,2006年后土地生态安全状况有所好转,处于临界安全状态.表明利用物元模型进行区域土地生态安全评价是可行的,具有计算简便、意义明确、评价精度高等优点,为土地生态安全评价提供了另一种途径.

关 键 词:物元模型  生态安全  鄱阳湖生态经济区

Abstract:Base on the 2001-2007 related statistical data, and by means of matter-element model, an evaluation was conducted on the land ecological safety in Poyang Lake Eco-economic Zone. The land safety in the Eco-economic Zone was relatively fine in 2001, decreased to critical level in 2002-2004, and degraded to unsafe in 2005. From 2006, the safety level returned to critical, indicating a better safety status. This study showed that matter-element model had the advantages of simple calculation, clear indication, a...
Keywords:matter-element model  ecological safety  Poyang Lake Eco-economic Zone
