Geography

Xiamen is a sub-provincial city in southeastern Fujian whose urban core grew up from the port of Xiamen on southern Xiamen Island, now located within Siming District. It now also includes Gulangyu Island and the rugged coast of the mainland from the northeast bank of the Jiulong River in the west to the islands of Xiang'an in the east. Xiamen Island lies about one degree north of the Tropic of Cancer. It is divided between Huli District in the north and Siming District in the south. Siming also includes Gulangyu. Its mainland territory is divided among Haicang, Jimei, Tong'an, and Xiang'an districts.

In the 19th century, Xiamen's harbor on Yundang Bay was considered one of the world's great natural harbors. Land reclamation has since been used to fill in the mouth of this inlet, turning it into Siming District's Yundang Lake. The municipal government is located on other reclaimed land beside it.

The nearest point of Liehyu in the Kinmen Islands, Republic of China (Taiwan), lies only 6 kilometers (4 mi) off Xiamen Island.

Xiamen Island is the fourth largest island in Fujian province. It became a peninsula after the completion of the seawall in 1955. Xiamen waters include Xiamen Port, Outer Harbor Area, Maluan Bay, Tongan Bay, Jiulong River's estuary area and the waterway on the east side. Outside the Xiamen Port, Big Kinmen, Little Kinmen, Dadan, Erdan and other island are arranged in a horizontal line. Inside, it has Xiamen Island, Gulangyu Island and other island barriers, making it a good natural port protected from storms.
