Abstract

In this study, rates of weathering and soil formation on granite and their dependences on acid precipitation were studied in a small forested watershed, Fengxingzhuang (FXZ), in subtropical China using geochemical mass balance equations and multiple regression analysis. Atmospheric input from wet and dry deposition, and stream output through runoff were monitored from March, 2007 to February, 2010. The physical and chemical properties of soil and granite rock were also determined. The results show that acid precipitation is very severe in the FXZ forested watershed. A proposed model that quantitatively describes weathering and soil formation rates is a combined product of rainfall amount and air temperature resulting from multiple regressions, which improves the prediction from simple linear regression
