| 摘 要： | 卤水中的化学成分因受多种因素影响,使其在时间序列上的变化波动强烈而规律难循。灰色—马尔科夫过程预测是预测事物在时间序列上发展趋势的一种良好有效的统计分析手段,它将灰色系统预测法和马尔科夫过程预测法有效结合,既弥补了两种方法各自的缺点,又能充分考虑数据给予的信息,可以大大提高随机波动较大数据序列的预测精度。本文用灰色—马尔科夫过程预测法对吉兰泰盐湖卤水中几种主要离子浓度的变化进行了趋势分析,分析结果发现几种离子浓度的变化均有一定的规律性,而且这些离子在预测数据的变化规律同原始实测数据变化规律有很好的一致性。

| Abstract: | There are so many factors influencing the evolution of salt lake brine, which cause the brine chemical composition changing randomly. Grey-Markov process prediction is an effective method to predict the development trend of time sequence. The combination of Grey system and Markov process can make up for the shortcomings of them, fully use the given data, and improve the prediction precision of stochastic fluctuating data sequence by bring a more objective and accurate result. Grey-Markov process prediction method was applied to analyze the trend of several major ionic concentrations in Jilantai salt lake brine in the paper. It was found that the ionic concentration change has the regularity, and the change between the predicted data in the future and the original data being similar. |
