海州湾位于苏北,其南岸(灌河口至临洪口)是一段极有趣的海岸,它几经黄河改道的影响,由原来的沙质、基岩港湾海岸改变为淤泥质海岸,现在正遭受严重冲刷破坏,致使湾顶区产生淤积。从全球角度来看,淤泥浅滩一般发育在沙坝后面或隐蔽的海湾顶部,而海州湾面向开阔外海,毫无任何阻挡,却广泛发育着淤泥质潮间浅滩,实属罕见。因而这段海岸对研究海岸带的形态与动态过程具有十分重要的意义。其次,这段海岸又位于 Haizhou Bay is located in the northern Jiangsu Province. Its south bank (Guanhekou to Linhongkou) is a very interesting coast. After being diverted by the Yellow River, it changed from the sandy coast to the silt coast and is now suffering from Severe scouring damage, resulting in siltation Bay top area. Globally speaking, silt banks usually develop behind sand bars or at the top of covert shelves. Haizhou Bay is open to the open sea without any barrier. However, it is rare for silt intertidal shoal to develop extensively. Therefore, this section of the coast is of great significance for studying the morphology and dynamics of the coastal zone. Second, this section of the coast is located again
