| 摘 要： | 利用生态足迹和生态系统稳定性评价模型,在分析区域内土地利用特征的基础上,测度区域土地资源生态安全态势及生态系统稳定性,揭示了宝鸡市及其各分区土地资源生态安全度的差异,为进一步研究土地生态安全格局下的土地利用优化配置及发展生态友好型土地利用模式提供参考依据。结果显示：2006年,中部川塬区土地资源生态安全度为2.451,处于不安全状态;南部中高山地区为0.541,处于较安全状态;北部山地丘陵区为0.837,处于临界安全状态;宝鸡市土地资源生态安全度总体为1.778,处于不安全状态。

| Abstract: | The evaluation model of eco-footprint and eco-system stability was used in 2006 to measure the eco-security and eco-stability of land resources in Baoji City,based on regional land-use characteristics,and the different results of the eco-security of land resources between Baoji and its sub-regions were revealed.It is shown that the eco-security of the plateau region situated in the middle area of the city is 2.451 and in a state of insecurity;the southern alpine area is 0.541 and in a less security status;t... |
