煤炭资源型城市土地生态安全测度评价——以平顶山市为例

Analysis of Land Eco-Security in Coal Resource-Typed City:Taking Pingdingshan as an Example

运用生态足迹方法分析平顶山市2003～2007年的生态足迹构成及土地生态安全,初步探讨平顶山市土地生态系统安全状况。结果表明,平顶山市对资源的利用效率较低,土地生态系统处于超负荷的危险状态。

By the ecological footprint model, the composition and the dynamic change of ecological footprint in Pingdingshan City 2006-2007 are analyzed, and the land ecological security of Pingdingshan City is studiedl The results indicated that the land resource of Pingdingshan City was almost in the ecology over burden condition, suggesting that the land ecological environment is at risk.
