鲁南海岸的范围,系指从两城河口至绣针河口这段海岸。从两城河口至绣针河口海岸全长70公里,行政区划属山东省日照县范围(图1)。本区海岸从物质组成上虽属较平直的砂砾质、基岩港湾式海岸,但湾外目前已多被砂埙、泻湖围封,故也可视为砂坝、泻湖岸。本区海岸除南段绣针河口、北段两城河口和中段傅疃河口属河口三角洲型海片,石臼咀、奎山咀及岚山岬等处属海蚀型海岸外,其间的绝大部分岸段均属砂坝、泻湖海岸。
The range of the coast of Lunan means the coast from the estuary of the two cities to the embroider’s mouth. The total length of 70 kilometers from the estuary of the two cities to the embroider needle estuary is within the administrative area of Rizhao County, Shandong Province (Figure 1). Although the coast of this area is relatively flat gravel and bedrock bay coast from the material composition, it is now more sandblasted and lagoon enclosed, so it can also be regarded as sand bar and lagoon shore. In addition to the coast of the region, the southern section of the Embroidery Strait, the northern section of the two urban estuaries and the middle section of the Fu River estuarine estuary deltas, Shijiu Tsui, Kui Shan Tsui and Arashiyama Cape and other places are at sea near the coast, the vast majority of Shore section is a sand dam, lagoon coast.
