%X Interpolation applications on grain size parameters distribution of surface sediments in Heini Bay with GIS-based methods were discussed.Four interpolation methods(IDW,Kriging,Spline,NN) were compared and the factors influencing the interpolation accuracy were discussed from several aspects.The results indicate that considering interpolation accuracy and spatial expression IDW is relatively best among four interpolation methods in process of grain size parameter interpolation in Heini Bay.But bulls eye effe...
