The volume fractal dimension of soil particle had a highly significant positive correlation with the volume percentage of soil physical clay (<0.

In addition,the As concentration has positive correlation with the percent of clay and has negative correlation with pH,the organic matter,the total nitrogen and the percent of silt.

A study was implemented in the abandoned riverway of Yellow River Estuary,Diaokou,on the influence of clay,organic matter and biologic EPS(extracellular polymeric substances) on the aggregation.
