Guanyun County (simplified Chinese: 灌云县; traditional Chinese: 灌雲縣; pinyin: Guànyún Xiàn) is under the administration of Lianyungang, Jiangsu province, China. It borders the prefecture-level city of Suqian to the southwest and the Yellow Sea to the east. Guanyun County has an area of 1,538 km2 (594 sq mi) and a population of about 1,026,000 as of 2020.[2]
Toponymy
The name Guanyun is made of two Chinese characters, guan (Chinese: 灌; pinyin: guàn) and yun (simplified Chinese: 云; traditional Chinese: 雲; pinyin: yún), which are taken from the Guan River and Yuntai Mountain, which are both important landmarks in the county.
History
The area of present-day Guanyun County was a major salt-making site for the Qing dynasty.
The county was formally established in April 1912.[2][3]
Geography
Guanyun is a coastal city of the East China Sea (the Yellow Sea) with a coastline of 32 km (20 mi). It borders Guannan County), Xiangshui County, Lianshui County, and Shuyang County.
The Guan River flows through the county eastwards into the East China Sea. The river is 77.5 km (48.2 mi) in length and its main tributary is Sihe River, flowing through the southern portion of the county.
A number of whales from the sea have been sighted swimming back into the river's waterway as deep as 10 km (6.2 mi) in recent years, prompting the formation of tough government regulations meant to minimize the impact of pollution on the county's water and environment.
Climate
Guanyun is situated in the north of Jiangsu Plain and has an oceanic monsoon climate, with distinct four seasons, like most of its neighbors. The annual average temperature is close its neighbors 15 °C, with 25 °C in summers and 5 °C in winters. Average rainfall is close to 1,000 m annually.
