Which area is larger, Beibu Gulf or South China Sea?

The formation of the bay is because the coastal rocks extending to the ocean are hard and soft, and the weak rock layers are constantly eroded and concave to the land. Generally speaking, the bay is U-shaped or arc-shaped, surrounded by land on three sides and ocean on the other side. The earth has formed different ocean forms because of ocean movement. There are many bays in the world, among which there are five bays with an area of over 6.5438+0 million square kilometers. Do you know which of the five bays in China are? Now Bian Xiao, the ranking network of Bala, has counted five bays in China, of which Beibu Gulf is the largest. If you want to know more, let's read it!

The five largest bays in China.

1, Beibu Gulf

Beibu Gulf is the largest bay in China, located in the northwest of the South China Sea, bordering Leizhou Peninsula and Hainan Island in the east, Guangxi in the north and Vietnam in the west, with an area of about 6.5438+0.3 million square kilometers, slightly larger than the Bohai Sea. The Red River and Nanliu River flow into the bay, bringing less sediment, and the water depth gradually deepens from the shore to the middle, with an average water depth of 42 meters.

Beibu Gulf is rich in resources. Because of the rich bait, there are more than 50 kinds of fish with economic value here, such as snapper, golden thread fish, sardine, mackerel, tuna, flounder, pomfret and mackerel, as well as shrimp, crab and shellfish. This is one of the best fishing grounds in China. The coastal shallow sea is a vast beach, which is an excellent place to develop mariculture. Shellfish include oyster, pearl oyster, sun-moon oyster, mud clam and so on. The world-famous Hepu Pearl (also known as Nanzhu) is produced here. Weizhou Island, Yinggehai and other seabed oil and gas resources are also considerable. There are many mangroves in coastal estuaries.

2. Hangzhou Bay

Hangzhou Bay is located in the northeast of Zhejiang Province, China, with the southern margin of the Yangtze River Delta on the north bank and Ningshao Plain on the south bank, which is the largest tidal range along the coast of China. The coastal cities are Shanghai, Jiaxing, Hangzhou, Shaoxing and Ningbo.

Qiantang River and Caoejiang River are injected. The sea area is about 5200 square kilometers. Due to the special topography of Hangzhou Bay, tidal bore and tidal bore often occur here. It is called the tidal bore of Qiantang River, which is the largest tidal range along the coast of China, with the largest tidal range of 8.93m (Ganpu) in history. The sediment in Hangzhou Bay mainly comes from the sea area, and the sediment in the Yangtze River plays a great role in its formation, with fine and loose sand particles and low impact resistance.

There are two famous bridges in this bay, namely Jiashao Bridge and Hangzhou Bay Bridge.

3. Bohai Bay

Bohai Bay is located in the west of Bohai Sea, starting from Daqing estuary in Laoting County, Hebei Province in the north and reaching the Yellow River estuary in Shandong Province in the south. Coastal cities mainly include Tangshan, Tianjin, Cangzhou and Dongying. There are rivers such as Hebei Canal and Haihe River. The sea area is about 1.6 million square kilometers. The seabed topography is generally from south to north, and inclines from the shore to the sea. The sediments are mainly fine silt and silt. Bohai Bay is rich in oil reserves. Its north is a famous tourist and holiday resort, and Tanggu in the west is an important port.

Bohai Bay belongs to a warm temperate maritime monsoon climate, with hot Leng Xia in winter, four distinct seasons, short spring and autumn and short rainy season. There are abundant oil and gas resources here and great oil-bearing prospects. There are many benthos and plankton, and the largest salt factory in China is here.

4. Laizhou Bay

Laizhou Bay is the largest bay in Shandong Province, together with Liaodong Bay and Bohai Bay, it is called the three major bays in Bohai Sea. It starts from the high corner of Qimu Island in the east and reaches the mouth of the Yellow River in the west, covering an area of 6,060 square kilometers. Laizhou Bay has an open water surface and gentle underwater terrain, and most of the water depth is within 10 meter, so it is not suitable for building an excellent harbor.

The rich nutrition brought by the Yellow River makes Laizhou Bay an important fishing ground in China, especially famous for shrimps. There are abundant seabed oil and gas resources and fishery resources here.

5. Liaodong Bay

Liaodong Bay is the highest latitude bay in China, located in the sea area from the mouth of Daqing River in Hebei Province to the north of Laotieshanjiao at the southern tip of Liaodong Peninsula. The seabed topography inclines from the north shore and both sides to the center. The water depth on the east side is greater than that on the west side, and the center of the bay is flat. Depositing black and slightly smelly sludge.

Because it is located in the north, Liaodong Bay is also the bay with the lowest seawater temperature and the most serious ice condition in China. This bay is rich in products, such as sea cucumber, eel and abalone.

Besides these five bays, there are many famous bays, such as Jiaozhou Bay, Weihai Bay, Haizhou Bay, Sansha Bay, Xinghua Bay, Meizhou Bay, Quanzhou Bay, Daya Bay, Mirs Bay and leizhou bay.
