Abstract

The aim of the present investigation was to research the distribution characteristics of copper in water and sediment of the Liao River, China. The concentrations of copper in water and sediment showed significant difference at different sampling stations. The distribution characteristics of copper in water and sediment were obtained by using discrete and continuous numerical characteristics. The results indicated that the average concentrations of copper in water and sediment decreased slightly after its accumulation. While the deviations of the concentrations of copper in water and sediment from the expectation increased significantly after its accumulation. The skewness distributions of the concentrations of copper in water and sediment did not change much before and after its accumulation. The kurtosis distributions of the concentrations of copper in water and sediment decreased significantly after its accumulation. Therefore, the precise distribution characteristics of copper in water and sediment were obtained through the combination of the discrete and continuous numerical characteristics.

数值特征在辽河铜分布特征中的应用

本文旨在研究辽河水体和沉积物中铜的分布特征。不同采样点水体和沉积物中铜的含量差异显著。利用离散和连续的数值特征得到了铜在水体和沉积物中的分布特征。结果表明，水体和沉积物中铜的平均浓度在积累后略有下降。而水和沉积物中铜的浓度在积累后与预期值的偏差明显增大。水体和沉积物中铜浓度的偏度分布在铜富集前后变化不大。水体和沉积物中铜浓度的峰度分布在铜积累后显著减小。因此，通过离散和连续数值特征相结合，获得了铜在水体和沉积物中的精确分布特征。
