摘要: 通过2007~2017年闽江污染物入海总量的调查数据,利用时间序列对各污染物入海总量的变化趋势进行模拟,并预测2018年闽江污染物入海情况。结果显示:2007~2017年油类污染物及重金属类污染物入海总量持续下降,而有机污染物和营养类污染物入海总量则表现为上升趋势。预计2018年有机污染物、营养类污染物、油类污染物及重金属类污染物入海总量分别为1 115 341、418 058、619和479 t,与2017年相比保持稳定。Abstract: Based on the survey data of the total amount of pollutants into the sea in Minjiang River from 2007 to 2017, time series were used to simulate the change trend of the total amount of pollutants into the sea, and the situation of the pollutants in Minjiang River entering the sea in 2018 was predicted. The results showed that the total amount of oil and heavy metal pollutants into the sea decreased continuously from 2007 to 2017, while the total amount of organic and nutrient pollutants into the sea showed an increasing trend. The total amount of organic pollutants, nutrients pollutants, oils pollutants and heavy metal pollutants into the sea in 2018 was predicted to be 1 115 341, 418 058, 619 and 479 tons respectively, keeping stable compared to that in 2017.
