摘要

There are many factors that influence the quality of marine water. In order to make the evaluation process more efficient and accurate, based on the normal distribution principle and Bias formula, this article establishes the seawater quality evaluation model by Bayesian method. Taking the evaluation of water quality of a sea area in Qingdao as an example, the measured data of eight water quality monitoring points are selected. The results of the evaluation are compared with the grey relational analysis. It shows that the results of the two methods are the same, which are the I type of water quality. So the Bayesian method based on normal distribution is applicable to the evaluation of marine water quality and the Bayesian method has the characteristic of more integrated, suitable for both large and small samples, simple calculation and easily to be used widely.
