粒度趋势分析表明，渤海海峡泥沙输运具有两个明显的特征。山东半岛西部和沿着地区以向东输送为主。这一结果支持了前人关于黄河沉积物从渤海经渤海海峡南槽输往黄海，并沿着山东半岛沿岸分散入南黄海的观点。在渤海海峡中东部，正发生净沉积，粒度趋势的收敛表明。这一结果与渤海海峡现今环流格局和地震反射剖面所揭示的地层解释相一致。这项研究支持使用粒度趋势分析的大规模地区的大陆架。
Grain size trend analysis indicates two distinct characteristics of sediment transport in Bohai Strait. Eastward transport dominates the western area and along the coast of the Shangdong Peninsula. This result supports the previous work which indicated that the Yellow River sediments are transported from the Bohai Sea to the Yellow Sea through the south channel of Bohai Strait, and dispersed into the southern Yellow Sea along the coast of Shangdong Peninsula. In the central eastern Bohai Strait, net deposition is taking place, as indicated by the convergence of the grain size trends. This result is consistent with current circulation pattern on Bohai Strait and the interpretation of strata disclosed by seismic reflection profile. This study supports the use of grain size trend analysis for large-scale areas on the continental shelf.
