摘要: 根据2003年至2012年闽江口海域海洋境监测数据,对该海域海水中重金属Hg、As、Pb、Cd、Cu、Zn的变化情况进行研究与分析;建立ARIMA模型,对未来两年含量趋势变化进行预测。结果表明2003年以来,闽江口海域海水中Pb、Cd、Cu含量相对稳定,无较大波动及变化,其余各重金属元素的含量也呈逐年稳定的趋势;应用ARIMA模型预测表明,未来两年闽江口海域海水中各重金属元素含量均与2003—2012年度平均值的平均含量接近。

Abstract: The contents of the heavy metals such as Hg、As、Pb、Cd、Cu、Zn in the seawater near Minjiang Estuary are determined and the distribution law is obtained from 2003 to 2012. Using ARIMA model to forecast the trend of contents within the next two years. The results showed that the contents of Pb, Cd, Cu are relatively stable near Minjiang Estuary since 2003,while the other contents of the heavy metals are steady yearly .The analysis of ARIMA indicated that the contents of heavy metals within the future two years will be close to the average annual contents in 2003~2012。
