In China, the north-south dividing line is along the Huaihe River and Qinling Mountains. The cities to the north of this dividing line are all northern cities, and the cities to the south are all southern cities. Shanghai belongs to China, a municipality directly under the Central Government of China and a national central city.

Shanghai is the financial center of China, including Shanghai Stock Exchange, Futures Exchange, China Financial Exchange, Shanghai Diamond Exchange, Gold Exchange, Financial Derivatives Exchange, Inter-bank Bond Market and China Foreign Exchange Trading Center.

Metal mineral resources

Shanghai is short of metal mineral resources, building stones and energy minerals on land. Since 1970s, we have been searching for oil and gas resources at sea, and obtained industrial crude oil and natural gas from several wells.

According to preliminary estimation, the oil and gas resources on the continental shelf of the East China Sea are about 6 billion tons, which is the largest oil and gas basin in China offshore. Through investigation and exploration, oil and gas resources have also been discovered in the nearby South Yellow Sea, with an estimated reserve of 290 million tons. The East China Sea is rich in chemical resources, and some abnormal mineral areas, such as zircon, ilmenite, garnet, rutile and other important minerals, have been found in the shallow waters of the Yangtze River estuary.

Shanghai's water resources are mainly composed of Huangpu River and other rivers in the city. The average annual runoff of Huangpu River is more than 300 cubic meters per second, with an average annual runoff of 654.38+000 billion cubic meters. Together with the flow of other rivers in Shanghai, the average annual runoff of water resources in Shanghai totals 654.38+0.45 billion cubic meters. Due to some exogenous factors, the annual water volume changes greatly, generally fluctuating within the range of 5 billion to 23 billion cubic meters.
