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.
