| 摘 要： | 以河流为主线,以流域为单元,根据生态系统内部诸因子的相关性以及绿洲与荒漠两大生态系统间的耦合机理,对交错带生态环境通过利用层次分析法对指标进行定量分析确定其权重,得出了该带生态环境的危险程度定量结果.层次分析法对于田绿洲生态环境安全评价指标权重的确定结果基本符合实际,可以为解决生态安全评价中分配各个评价因子的权重提供行之有效的技术方法,同时为生态安全综合评价和推广提供一种有效的判断依据.

| Abstract: | In this paper the ecological environment in oasis-desert crisscross region and evaluation index of environment security were analyzed,based on the correlation of all the factors in ecosystem and coupling mechanism between the two great ecosystems,such as oasis and desert.The quantitative result of danger extent in ecological environment zone was obtained.The analytical hierarchy process(AHP)was of meaning for the index of security evaluation of oasis ecological environment.It could provide the technical effective method for solving the weight of evaluation factors in the ecological security evaluation.It also could provide the effective basis for the comprehensive evaluation of ecological security. |
