Rizhao Coast

Rizhao's shore runs 99.6 kilometres, from the mouth of the Tianshui river in the north to the mouth of the Xiuzhen river in the south, and it is comparatively straight: bedrock sand and gravel. Two natural bays break it, at Shijiu and at Foshou, and the city's port group is made up of Rizhao Port and Lanshan Port. Near the coast lie the islands of Taohua and Chufeng, and further out three small islands, Pingdao, Dashan and Che'niu Shan, with a combined area of 0.321 square kilometres. The land and the shallow water behind are given over to the sea as well, with tidal flats, a 10-metre depth line and a million mu inside the 20-metre line counted as aquaculture ground.
