摘要：
元素地球化学研究表明，长江与黄河对冰后期的苏北滨海平原发育与苏北南黄海潮成砂体的形成影响巨大。冰后期早期长江物质影响大于黄河。黄河供给泥沙量较少，且对本区影响主要在北部、中部地区。公元1128年黄河改道由苏北入海之后，黄河影响范围明显大于长江。长江仅由个别狭窄的汊道提供有限的物质而影响范围较小。古长江主流并未由琼港地区入海，而携带大量物质建设潮成砂体。最近2000年来本区沉积物主要由黄河提供。分析表明元素地球化学方法在沉积物物源判别时，可有效的避免水动力因素影响，取得较好的效果。
Abstract:
The postglacial sedimentary strata developed in north Jiangsu Coastal Plain mainly include littoral facies, offshoreneritic facies and tidal flat facies from the lower part to the upper part. Element geochemical study shows that the Changjiang and the Huanghe Rivers have a great influence on development of north Jiangsu Coastal Plain in postglacial period. During the early stage, the Changjiang's influence exceeded the Huanghe's, especially in the southern and middle part of north Jiangsu area, whereas the Huanghe River only transported small amount of matter and mainly influenced the northern part. After the postglacial transgression maximum, the Huanghe's influence was stronger than the Changjiang's, and only a narrow tributary of the Changjiang River transported limited amount of matter to Qianggang and Sancang area. The mainstream of the Changjiang River did not enter to sea via north Jiangsu area, so it did not carry much matter to form the tidal sand bodies either. During the last two thousand years, sediments of this area were mainly from the Huanghe River. Study also shows that element geochemical method is useful in provenance discrimination, because it can effectively avoid the influence of hydraulic sorting.
