Which province is Zhoushan?

Zhoushan is a prefecture-level city in Zhejiang Province.

Located in the northeast of Zhejiang Province, it is adjacent to the Pacific Ocean in the east, Xiangshan County in the south, Hangzhou Bay in the west and Shanghai in the north. With a total area of 22,200 square kilometers, up to 2065,438+06, the city has two municipal districts and two counties.

In the fifteenth year from Yuan to Yuan, it was promoted to Zhou because of "dangerous sea route" and "ten thousand accounts". In the twenty-third year of Emperor Kangxi of Qing Dynasty, the imperial court promulgated the Order of Exhibition of Seas, which opened the sea ban, Zhoushan began to recover, and fishery agriculture gradually flourished. After the Revolution of 1911 (19 1 1), Haixian was newly established. In September, 1978, Zhoushan administrative office was established.

Zhoushan is backed by the vast hinterland of Shanghai, Hangzhou, Ningbo and the Yangtze River Delta, facing the Pacific Ocean, and has a strong geographical advantage. It is located at the intersection of China's north-south coastal route and the Yangtze River waterway. It is the maritime gateway and channel for the Yangtze River Basin and the Yangtze River Delta to open to the outside world, radiating fan-shaped from emerging port cities in the Asia-Pacific region.

Hydrological characteristics of Zhoushan

The hydrological situation in Zhoushan City is complex, and the surface water system is underdeveloped. Most of them come from the hinterland of hills and meander radially into the sea. The water system is affected by the size of the island, with short flow and small catchment area. Affected by heavy rain, the water level has soared and plummeted, which is easy to cause natural disasters such as flash floods.

Coastal tide belongs to irregular semidiurnal tide, which is characterized by reciprocating flow. The high tide goes west and the low tide goes east, and the high tide velocity is greater than the low tide velocity. Seawater tides and typhoon waves have great influence on the coast of the island, especially in the intertidal zone.
