Riparian soil physicochemical properties and correlation with soil organic carbon of an inflowing river of Taihu Lake

Abstract

Profile method and the classic measurement method were used to analyse the vertical distribution of riparian soil physicochemical properties of an inflowing river (Yincungang River) of Taihu Lake. The results showed that the soil physicochemical properties distribution of the riparian zones with three different vegetation communities were showed a similar regular change tendency with the increase of soil depth. But the maximum of soil organic carbon (SOC), total nitrogen (TN) and total phosphorus (TP) were occurred in the riparian zone with Arundo donax community, and the maximum of soil bulk density (BD) and pH value were occurred in the riparian zone with phragmites australis community. Besides, there was significant positive correlation between SOC and TN, TP, BD, while the opposite result was observed for pH.
