| 摘 要： | 为了分析各种密切值法的特点,选择最佳的地下水水质评价方法,叙述了传统密切值法、改进的密切值法、基于熵权改进的密切值法、基于熵权的密切值法的方法原理,并以内蒙古东胜煤田阿不亥普查区的地下水水质综合评价为例,用上述各种密切值法进行地下水水质评价,将评价结果与模糊数学法的评价结果进行对比,分析各种评价结果的合理性。结果发现:当各水样的检测值差别相对较大时,采用目标差值率法对初始环境矩阵规范化处理,会过分夸大该指标在水质评价中的作用,所以改进的密切值法和基于熵权改进的密切值法在这种情况下评价结果很不理想。运用信息熵原理确定各指标的权重,综合考虑了各种信息,弥补了传统的密切值法的缺点,基于熵权的密切值法是各种密切值法中最合理的评价方法。
