为了解决现有研究对生态载体安全状态研究缺失导致的生态安全判断不准确的问题,以临湘市为例,依据生态安全内涵,首先运用改进的生态足迹法,完成资源流动层面安全状态的判断,然后结合能值法的理论和系统学方法,构建生态载体安全等级划分体系,完成了生态载体层面安全状态研究,最终得出生态安全评价结果。结果表明:(1)从整体上看,2005—2017年临湘市在资源流动层面上处于安全状态;生态载体安全等级由Ⅳ-U级到Ⅱ-D级,生态载体安全状态经历了稳定上升又下降的波动过程,区域生态载体整体现状处于安全状态,因此得出临湘市处于生态安全状态。(2)从地类变化看,2005—2017年除化石能源用地外,其他地类均处...

In order to solve the problem of the inaccurate judgment of ecological security caused by the lack of research on the security status of ecological carriers in the existing research,Linxiang City was taken as the example.Based on the generally accepted connotation of ecological security,the improved ecological footprint method was used to complete the judgment of the security status at the level of resource flow,and then the theory of emergy method and systematics method were combined to construct the security classification system of ecologica...
