Some microelements totalled ten of sediment samples have been analysed by emission spectrometer. The samples taken from the nearshore area of the Huanghe River and the Lianhe River and the elements analysed are Ni, Co, Cu, Ga, V, Ti, Pb, Zn, Mo, and Mn. Though multivariate analysis by computer, it shows that the effective discriminant elements for the sediments of estuary area of the Huanghe River and Lianhe River are Ti, Zr, Co, V. The Lianhe River Estuary sediments are characterized by higher content of Zr, Co and the Huanghe River Estuary sediments are characterized by higher content of Ti,V. The trend surface analysis shows that the Ni, Ga, Co and Cu have similar tendency of distribution and are closely related with the clayey sediments; Zr and Ti have the similar trend distribution and closely related with coarser grain sediments; the distribution of Mn is in accordance with the area of higher pH. Eh values and is closely related with fine-sandy sediments.
