海岸线长达700多公里的鲁南沿海大部分属基岩港湾式海岸。岸线曲折,港湾众多,水深条件良好,没有泥沙淤积之患,工程地质条件特别优越,是我国北方一个极好的建港地段。从胶州湾到海州湾北部,有许多地方具有建港条件,有些地段甚至可以建设现代化的深水大港,除青岛港和正在动工兴建的石臼所港外,还有许多地方也具备建设大 Most of the coastal areas along the coast of Lunan, more than 700 kilometers long, are bedrock bay coasts. There are many twists and turns in the coastline, numerous bays, good water conditions and no sedimentation. The engineering geological conditions are particularly superior. It is an excellent port for construction in northern China. From Jiaozhou Bay to the northern part of Haizhou Bay, many places have the conditions of establishing a port. In some areas, even modern deep-water port can be built. In addition to Qingdao Port and Shijiu Port under construction, many places also have large-scale construction projects
