摘　　要：针对城市水生态安全评价的不确定性与模糊性特征,运用基于模糊系统分析的方法对北方四城市的水生态安全评价指标体系分析并优化,并对四城市水生态安全状况进行模糊综合评价研究,以揭示影响城市水生态安全的主要影响因子。结果表明,北方四城市的水生态安全受人类经济社会活动影响较大,利用本方法进行水生态安全评价是合理可行的,可为区域水生态安全管理提供科学依据。In accordance with the uncertainty and fuzzy feature of the safety assessment on urban water ecology,a fuzzy system analysis-based method is applied to the analysis and optimization of the index system for the water ecology safety assessment made on the four cities in the North China（ i. e. Lanzhou,Xi＇an,Beijing and Xining）,and then the study on the fuzzy comprehensive assessment of the water ecology safety status of the four cities is made as well,so as to reveal the main factors to impact the safety of the urban water ecology. The result shows that the water ecology safeties of the four cities are largely impacted by the human economic and social activities,while the method introduced herein is reasonable and feasible for the water ecology safety assessment concerned and then can provide a scientific basis for the safety management of the regional water ecology.
