Abstract To study the space distribution characteristics of critical starting velocity of sediments in the northern South China Sea(SCS)，the 45 stances sediment physical property data of corresponding area has been collected and self-test，then calculating the critical starting velocity by choosing appropriate formula and evaluating the applicability of the results. According to the sediment space distribution and statistical results，112 stances sediment critical starting velocity values have been received by interpolation and drawn. The results show that sediments critical starting velocity is different in the space. The distribution of sediment particle size corresponds with distribution characteristics of critical starting velocity substantially and controls it. Compared with upper laminar flow field in the northern SCS，the degree of starting difficulty of the seabed sediments continental shelf in the winter and summer has been gained，which provides the basis to study the transformation mechanism of seabed sediment by ocean dynamics and change rule of seabed sediment in the northern SCS.

Key words： soil mechanics Northern South China Sea sediments critical starting velocity spatial distribution characteristics re-suspension
