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, and higher accuracy, being able to provide another approach for regional land ecological safety evaluation.
