中文摘要：

结合钻孔与探地雷达探测古海相层尖灭点的测量方法与图像处理原则，本研究在沿渤海西南岸分布的8个相关钻孔附近开展了探测，经图像处理、与钻孔对比分析以及在特征位置钻探浅钻的方式，获得了5处最大海侵尖灭点的位置、地层剖面形态以及高程等信息。结合6kaB．P．、2kaB．P．左右和现代黄河流路变迁史及沿岸贝壳堤分布情况，揭示了最大海侵时期小清河向北至漳卫新河范围主要为古黄河形成的广阔三角洲潮滩地貌，海侵线远离海岸线深入内陆，其上的贝壳堤形成主要与黄河流路变迁相关；而渤海湾西南岸黄骅、沧州附近及以北主要为沼泽一渴湖一沙坝海岸地貌特征，海侵线由渴湖的陆侧边缘向海逐渐推进，沿岸分布的6kaB．P．左右贝壳堤的形成则是基于沿岸堤，并伴随风暴作用发育而来。莱州湾南岸依据埋藏古河道古湖泊的分布情况，推断该区全新世最大海侵前后具有与现代相似的海岸地貌特征，海侵时，海水直抵当时最大高潮线附近，使得海岸线与海侵线几乎相当。依据剖面地形校正结果可知，最大海侵时，海水侵入内陆至现代地表高程5．8-10．3m范围，后期新构造运动造成的隆起与下沉的区域差异，使得不同区域海侵层高程发生相应的变化，该结果为进一步估算海平面变化提供重要基础。

英文摘要：

Based on Ground Penetrating Radar （GPR） field measurements and the sedimentological facies log, we have carried out investigations in the neighborhood of eight boreholes located the southwestern coast of the Bohai Sea. The locations, configurations and altitudes of five marine facies deposits of the pinch-outs （boreholes ZK303, HN73, YS1, BDK1 and GZ2） formed during the maximum Holoeene transgression period have been obtained by a comparative analysis between GPR image and borehole record. The geomorphologic characteristics of coastal sedimentary have been discussed in study area during the maximum Holocene transgression period. The results show that widely delta tidal fiat had been formed from Xiaoqing River in Shandong Province to Zhangweixin River, the transgression range was far away from the shoreline in this region. However, lagoon-sandbar was major landform in the vicinity of Huanghua and Cangzhou in Hebei Province, suggesting that the transgressive boundary gradually moved to the sea. From the relationship between the historical courses of Huanghe River shifts and the distribution of shell cheniers during three period （6ka B.P., 2ka B.P. and recent years） , it is revealed that cheniers formation and delta progradation are related in the plain of the Huanghe River Delta in the vicinity of boreholes HN73 （37°39＇ 13.32＂N, 117°53＇27.32＂E） and YS1 （38°06＇06＂N, 117°28＇12＂E）. However, it originated from a longshore sand bar evolution process which meanwhile was subject to storm surge in the southwestern coast of Bohai Bay near the BDKl（38°19＇53.44＂N, 117°24＇47.98＂E） and GZ2（38°27＇03＂N, 117°05＇34＂E）. In the southern coast of the Laizhou Bay, it is inferred that there were similar characteristics of coastal geomorphology before and after the maximum Holocene transgression era as the modern coast location is compared the positions of buried ancient channel and lake, and in that time the shoreline almost was consistent with the transgression range.
