湘江地处亚热带,全长856公里,流域面积广,降水量丰富,它有大小支流两千余条,百公里以上的支流就有20余条。这些支流因流经地区地质构造和所纳废水来源不同,其水中含铀量也不同。根据湘江污染综合防治科研计划要求,我们测定了1980年湘江主流丰水期和枯水期若干断面水样中的含铀量。为了弄清主流不同断面含铀量的差异,在本工作中我们又进一步对湘江若干主要支流水中含铀量作了分析。
The Xiangjiang River is located in the subtropical zone with a total length of 856 kilometers and a wide drainage area with abundant rainfall. It has more than 2,000 branches and tributaries and more than 20 tributaries of more than 100 kilometers. Due to the different geological structures and the sources of waste water, the tributaries have different amounts of uranium in the water. According to the requirements of the comprehensive scientific research plan for the prevention and control of Xiangjiang River pollution, we measured the amount of uranium contained in the water samples of a number of sections during the wet and dry periods of the Xiang River in 1980. In order to find out the difference of uranium content in different sections of the mainstream, we further analyzed the amount of uranium contained in the water of several major tributaries of the Xiang River in this work.
