Abstract: This paper dealt with the accumulation characteristics of 14 elements in the sediments of Erdaofang River. Correlation and regression analysis showed that the correlation coefficients of elements with similar geochemical properties in the sediments attained to a very significant or significant level. Based on factor analysis, four principal factors which represented 85% of measurement information of 14 elements were selected. With corresponding eigenvectors of first and second principal factors as ax is X and Y,the 14 elements were divided into three types. Multi regression models of most elements and sediment properties were established.
