摘要
The concentration of sulfate is high in Dengzhanhe karst spring located in the recharge area of Houzhai underground river of Puding, Guizhou Province. The results indicated that the sulfur isotopic composition was mainly controlled by dissolution of gypsum and oxidation of organic sulfur in soil; seasonal variation of sulfur isotopic composition was remarkable, and indicated that sulfur isotopic composition in dry season was more than that in rainy season, and the change of composition in dry season was small and mainly controlled by the dissolution of gypsum, but the change in rainy season was large and reflected the increase of organic sulfur for underground sulfate soil and its seasonal difference.
