京津地区的主要地表水源有永定河、潮白河、北运河、蓟运河和大清河等,属海河流域的一部分。长期以来,它们的水质是人们普遍关心的问题。本文从河流的稀有分散元素的含量及其形态来探讨它们的水化学特性与区域的背景值。
The main surface water sources in Beijing and Tianjin are Yongding River, Chaobai River, North Canal, Jiyun River and Daqing River, which are part of Haihe River Basin. For a long time, their water quality is a common concern. In this paper, the water chemistry characteristics and the background value of the area are discussed from the content and shape of the rare dispersed elements in the river.
