| 摘 要： | 区域生态安全评价需通过评价模型实现。而此类模型的构建则要克服理论、技术、方法、数据等方面的巨大障碍。文章根据生态环境系统的本质特征，对层次分析方法、灰色系统方法、模糊数学方法、变权方法等常用区域生态安全评价模型进行优化的复合，以期获得更加贴近实际情况的评价结论。在此基础上，构建层次分析-变权-模糊-灰色关联复合模型，作为区域生态安全综合评价的评价模型。 |

| Abstract: | Regional ecological security assessment can be attained by assessing model, the establishment of which has to overcome theoretical, technological, methodological, data difficulties. According to the essential characteristics of ecosystem, the paper optimally compounds the comprehensive models of regional ecological security assessment such as hierarchical analysis, gray system, fuzzy mathematics, variable weight, etc. , thus a-chieving the assessing conclusions which closely reflects the real situations. In this paper, the composite models of hierarchical analysis-variable weight-fuzzy-gray correlation are constructed and used as the assessing model for regional ecological security. The case study here shows that this model is the relative best one for regional ecological security assessment at the current stage and conditions. |
| Keywords: | regional ecological security comprehensive assessment model construction model optimization hierarchical analysis-variable weight-fuzzy-gray correlation composite models |
