关于渤海湾西岸内陆一侧第四道贝壳堤存在与否的问题,一直有争论。李世瑜提出的天津育英堂至静海四小屯有一道贝壳堤的推断。经过较多研究者的调查,并未得到证实。而黄骅苗庄的埋藏贝壳堤,却与张贵庄、巨葛庄的第三道贝壳堤相连。作者经过多次调查,发现苗庄的贝壳堤向北延伸至黄骅城东的沈庄,经王徐庄西-北尚庄-小王庄-孙庄-翟庄-阎北,至同居东。苗庄埋藏贝壳堤顶部埋藏土壤层(贝壳砂)、贝壳堤上部贝壳(文蛤)、中部贝壳(文蛤和近江牡蛎)和底部贝壳(文蛤)的C~(14)年代测定结果分别为距今3955±70、3955±70、4205±105、5235±140及4740±105年(赵希涛等,渤海湾西
There has been controversy over the existence of the fourth shell on the inland side of the western coast of the Bohai Bay. Li Shiyu proposed Yuying Church in Tianjin to Jinghai Si Xiaotun have a shell embankment inference. After more researchers survey, has not been confirmed. Huanghua Miaozhuang buried shell embankment, but with Zhang Guizhuang, giant Ge Zhuang third shell embankment connected. After many investigations, the author found that the shell embankment of Miaozhuang extends northward to Shenzhuang, east of Huanghua, and passes through Wang Xuzhuang West - Beishangzhuang - Xiaowangzhuang - Sunzhuang - Zhaizhuang - Yanbei to the east. The results of C ~ (14) dating of the buried soil layer (shell sand) at the top of buried seabed embankment in Miaozhuang, shellfish (clam) in the upper part of the shell dike, shellfish (clam and oyster) and bottom shell (clam) in the middle part of the shell are 3955 ± 70,3955 ± 70,4205 ± 105,5235 ± 140 and 4740 ± 105 years (Zhao Xitao et al., Bohai West Bay
