摘　　要：运用模糊数学基本理论和方法,以国家地表水环境标准为依据,对2004年5月至7月乌梁素海水质状况进行评价,并将实地水质监测结果与评价结果对照分析。评价结果与实际情况相符,能够比较准确地反映乌梁素海的水质等级变化。证实了模糊模式识别方法应用于湖泊水质评价中的合理性和可靠性,对于湖泊水质评价具有实际意义。Fuzzy pattern recognition theory is applied to evaluate the water quality of the shallow lake Wuliangsuhai located in arid district of Inner Mongolia, China. A water quality evaluation model based on fuzzy pattern recognition theory was established, and used to evaluate the water quality grade of 10 water quality monitoring stations in Wuliangsuhai from May, 2004 to July,2004. Analyzed the field survey data and the evaluation result contrastively, conclusions can be draw： the evaluation result correspond with the practical situation, and can reflect change of the water quality grade well. So it proved the rationality and reliability that fuzzy pattern recognition method applied in water quality evaluation of lakes.
