海洋环境基线值表达方式的探讨

Discuss of expressions on environmental baseline

从数理统计的角度探讨了环境基线值的表达方式,以2000年东海、黄海的实测数据为例,采用经典统计方法和稳健估计方法表示了基线值。结果表明通过稳健估计方法中的切尾均值和Winsor化均值可较准确地表达环境的基线值。

How to use mathematical statistics methods to express environmental baseline values were discussed. The baseline values of Donghai and Huanghai by using classical statistics and robust statistics were analyzed. The results showed that the trimmed mean and Winsorized mean could describe the baseline values accurately.
