针对正态样本的模糊综合评价法在巢湖水质评价中的应用
|
摘要
为克服模糊综合法进行水环境质量评价时的主观因素,假设水质指标在一段时间(如1年)内是服从正态分布的随机变量,从而引入概率,得出含义明确的隶属度函数。使用该函数后,评价结果具有足够的敏感度,通过计算综合污染指数,可以对比不同时间或不同水域水质的整体差异。将其应用于巢湖"合肥湖滨"断面9年的水质变化研究,证明了该方法的有效性。
To overcome the subjective factors of fuzzy comprehensive evaluation applied in water quality,the water quality indexes were assumed to be normal-distributed random variables, then the probability was introduced and a practical membership function was constructed. The method with the new function was sensitive to show a distinct difference in the comprehensive water quality of different time or waters by calculating a comprehensive pollution index. By researching 9-year water quality on Hefei section of Chaohulake,the method is proven to be effective.
