摘　　要：将水体视为1个灰色系统,将水质指标作为1个灰类,考虑水质分级界线的不确定性,采用灰色系统理论中的灰色关联分析方法进行地表水的水质评价。通过对乌梁素海进行的实例计算分析,结果表明,该方法比较准确,且在其他更广泛地区推广应用是合理可行的。The water body was regarded as a gray system and the water quality index was regarded as a gray category. Considering the indetermination of water quality classification, the water quality of the surface water was evaluated with the gray correlation analysis method of gray system theory. Given a example of Wuliangsuhai lake , analysis results showed that the method is more accurate and is reasonable and feasible to application in the wide area.
