| 通过E E S模型选择评价指标，而后选用模糊物元法建立评价体系，使用熵值法和层次分析法相结合的方式计算评价指标的权重;并对评价体系进行欧氏贴近度的计算，寻求主导城市生态系统安全的指标因子.以福建省为例，根据福建省近十年来的数据，对福建省的城市生态系统进行计算与评价.结果表明:福建省生态安全水平呈整体上升趋势，由临界安全转变为较安全，但系统各要素中部分指标有所恶化或反复. |

| Abstract: |
| With E E S model to decide the evaluation index first, then fuzzy matter element method is used to establish the evaluation system. The weight of evaluation index is calculated by the way in combination of the entropy method and AHP method, and then the evaluation system is calculated by Euclid approach degree to seek the index factors that dominate a city’s ecosystem security. Taking Fujian Province as an example, based on its data of last decade, this paper calculates and evaluates its urban ecological system. The results show that the ecological security level of Fujian Province presents an upward trend as a whole, but some indexes of each element in the system are deteriorated or relapsed. |
