摘要

Twenty-eight water samples were collected along the main channel and four major tributaries of the Yellow River during July 2005, and which silicon isotope compositions and chemical compositions of dissolved silicon and suspended matter in water were systematically researched. In this study, the δ³⁰Si value of dissolved silicon output from the Yellow River to the Bohai Sea is 1.1‰, lower than the δ³⁰Si of dissolved silicon （3.0‰） output from the Yangtze River to the East Sea, and also indicates that more further and detailed investigations to other rivers with different geographic and hydrological background are very important to study global silicon cycle.
