长江口水域氯离子浓度分布模型及预测模型

Distribution pattern and prediction model of Cl-concentration in the Yangtze Estuary

对长江口水域冷却水中氯离子浓度的样本数据进行统计分析,建立氯离子浓度分布的数学模型,氯离子浓度近似服从对数正态分布,并对比分析邻近水厂和电厂冷却水中的氯离子浓度,显示两者氯离子的浓度没有显著性差异,为预测全年水中氯离子的浓度提供依据,并给出最小样本容量的选取。

A distribution model of Cl- concentration was established based on the statistical analyses of Cl- concentration samples from the cooling water in the Yangtze Estuary. Results indicate that Cl- concentration in the area has a lognormal distribution. A comparison of Cl- concentration in the cooling water of a power plant with that in an adjacent water plant shows no significant difference, which will help in the prediction of Cl- concentration throughout a whole year. Finally, a minimal sample capacity is given.
