摘要
将正态分布原理与贝叶斯方法相结合来进行黄壁庄水库水质综合评价,并给出了改进的贝叶斯(Bayes)方法的思路和计算方法。以GB3838-2002为评价标准,采用改进的贝叶斯方法建立贝叶斯水质评价模型,对黄壁庄水库坝上水质监测数据8项指标进行水质评价研究。评价结果表明:改进的贝叶斯综合水质评价模型适用于黄壁庄水库的水质评价,且黄壁庄水库综合水质处于Ⅰ—Ⅱ类,年内水质变化不大,丰水期水质相对较差,为Ⅱ级水质,其余月份均达到Ⅰ类水质标准。
The Bayes method is based on the normal principles to analyze and evaluate the water quality of the Huangbizhuang Reservoir,the idea and calculation method of the improved Bayes method are also given.By using GB3838-2002as evaluation criterion,the improved Bayesian model for water quality evaluation is established through selecting water quality monitoring data on dam,Huangbizhuang Reservoir.The evaluation results show that the model is suitable for Huangbizhuang reservoir water quality simulation,the water quality of Huangbizhuang Reservoir is mainlyⅠandⅡgrade,while it is worse in the rain season for water quality beingⅡgrade,other months achieveⅠstandard.
