Spatial Distribution Characteristics of Organic Matter and Total Sulfur of Different Marsh Soils in the Yellow River Estuary

Abstract:

In 2008, we studied contents of soil organic matters (SOM) and total sulfur (TS) in the surface and subsurface soils in nine typical sampling points that covered with different plant communities in the wetland of Yellow River Estuary in order to identify the influences of different plant communities. Results showed the contents of SOM varied in irregular M mode except for 0-10cm soil layer. The characteristics of vertical distribution were resemble of different sites in the whole, decreasing along with the depth though existing some waves. The diversity was remarkable (C.V. > 10%), showing as medium variability. For TS, contents decreased with plant communities succession. But the characteristics of vertical distribution was not very significant. Correlation analysis showed that SOM contents had significant correlation with TN contents (r=0.955, p<0.01), TP contents were closely linked with SOM and nitrogen contents, but TS contents had no remarkable correlation with any other element.
