China claims the right to 12 nautical miles of territorial sea, i.e., the width of the territorial sea is 12 nautical miles from the baseline of the territorial sea, and beyond 12 nautical miles is not China's territorial sea. China's internal sea, territorial sea **** there are 370,000 square kilometers, China's jurisdictional sea area of about 3 million square kilometers. (China's ocean area of about 3 million square kilometers, the eastern and southern continental coastline of more than 18,000 kilometers, the waters of the inner sea and the side of the sea area of about 4.7 million square kilometers.

China is located in the eastern part of the Asian continent, facing the Pacific Ocean; adjacent to the edge of China's mainland, the Bohai Sea (Inland Sea), the Yellow Sea (of the western region that is the Yellow Sea of China), the East China Sea (of the Chinese region that is the East China Sea), the South China Sea (of the Chinese region that is the South China Sea) connected with each other, across the temperate zone, subtropical and tropical, from north to south in the form of an arc-shaped distribution is the edge of the western North Pacific Ocean sea. Because of the close proximity of the Chinese mainland, there is "China's near sea", is China's four seas.

The western part of the Yellow Sea is the territorial sea of China, and the eastern part of the Yellow Sea is the territorial sea of the Korean Peninsula. In the East China Sea, there is the China area, the Ryukyu Kingdom (a Japanese trusteeship rather than a Japanese territory) area, the Japan area, and the South Korea area. The South China Sea has the South China Sea inside the nine-dash line and many countries outside the line.

The Bohai Sea is China's inland sea, surrounded by land on three sides, between Liaoning, Hebei, Shandong and Tianjin provinces and cities. Specific location in the north latitude 37 ° 07 ′ ~ 41 ° 0 ′, east longitude 117 ° 35 ′ ~ 121 ° 10 ′. Liaodong Peninsula, the southern tip of the old Tieshanjiao and the north coast of Shandong Peninsula, Penglai, facing each other, like a pair of giant arms to the Bohai Sea, the shape of the shoreline surrounded by what looks like a gourd. Bohai Sea through the Bohai Strait and the Yellow Sea. The mouth of the Bohai Strait is 59 nautical miles wide, and there are more than 30 islands, of which the larger ones are South Changshan Island, Keji Island, Chin Island and Huangcheng Island, etc., collectively known as the Temple Island Archipelago or the Temple Island Islands. Between the composition of 8 wide and narrow waterways, the Bohai Sea throat, is the gateway to the Beijing-Tianjin region of the sea, the terrain is extremely dangerous. The Bohai Sea is called Canghai in ancient times, and because it is located in the north, it is also known as the North Sea. Bohai Sea area is small, probably only 90,000 square kilometers. The average depth of the Bohai Sea is 25 meters, and the total volume of the Bohai Sea is only 1730 cubic kilometers. Bohai coastal water is shallow, especially the river injection place is only a few meters deep; and the east of the old iron mountain waterway is the deepest, up to 86 meters. Bohai Sea water temperature changes by the northern continental climate, in February at about 0 ℃, in August up to 21 ℃. The onset of severe winter, in addition to Qinhuangdao and Huludao, most of the coast is frozen. early March ice melt also often occurs in large quantities of drift ice, the average water temperature of 11 ℃. As a result of the mainland rivers and rivers a lot of fresh water injection, and make the Bohai Sea sea water salinity is the lowest (only 30 ‰). Bohai Sea coast has Liaodong Bay, Bohai Bay, Laizhou Bay. Liaohe, Haihe, Yellow River and other rivers from the land to bring a lot of organic material, so that this place has become a rich shrimp, crabs and yellow croaker natural fishing grounds. The line connecting Cape Lao Tieshan at the southern end of the Liaodong Peninsula and Cape Penglai on the northern coast of the Shandong Peninsula is the dividing line between the Bohai Sea and the Yellow Sea.

It is like a slanting gourd, with its head resting on the Northeast Plain and sitting on top of the North China Plain. Liaodong Peninsula and Shandong Peninsula is like a pair of giant crab's chela, one left and one right tightly embraced it, leaving only the 105-kilometer-long Bohai Strait in a few narrow waterways and the outer sea, resulting in an almost closed sea situation. It is a shallow sea deep into the continent, the Bohai Sea composition, water temperature and many other aspects, y influenced by the continent. As far as 200 million years ago, the Bohai Sea and its surrounding areas, was a continuous land. Later, due to increased crustal activity, the area slowly sank. Onion dense primitive forest first became a basin, and then became a lake, 70 million years to 2.4 million years ago, the subsidence movement suddenly intensified, it became the Bohai Sea. This shows that the Bohai Sea is the ocean from the continent out of birth.

Yellow Sea China Zone Edit

The western part of the Yellow Sea is China's territorial sea, and the eastern part of the Yellow Sea is the territorial sea of the Korean Peninsula.

It is a marginal sea of the Pacific Ocean. It is between China and the Korean Peninsula. It is divided from the East China Sea by a line from the north coast of the Yangtze River estuary to Jeju Island in South Korea in the south, and is connected to the Bohai Sea by the Bohai Strait in the west. The area is about 380,000 square kilometers. The inflow of the river carries too much sediment, the near-shore seawater is yellow, hence the name. All for the continental shelf,

Average depth of 44 meters, the central part of the depth of 60-80 meters, the maximum depth of 140 meters. Salinity average of 31-32 ‰. Surface water temperature in summer is 25 ℃, winter 2-8 ℃. Transparency is about 15 meters in the south and 3-5 meters along the coast. Liaodong Peninsula, Shandong Peninsula and Korean Peninsula, the west coast of the zigzag, more harbor islands. Famous fishing grounds, rich in yellowtail, swordfish and so on. Salt industry is well developed. Out of the Bohai Strait, the sea suddenly open, the depth gradually increased, this is the Yellow Sea. Yellow Sea because of the Yellow River water inflow in ancient times, the river carried a lot of sediment, so that the seawater in the suspended material increased, the seawater transparency becomes smaller, so the yellow color, the name of the Yellow Sea is therefore obtained. The Yellow Sea is the sea defense outpost in North China, and is also the main sea route around North China. The Yellow Sea is bordered by the Shandong Peninsula and the North Jiangsu Plain in the west, the Korean Peninsula in the east, and the Liaodong Peninsula in the north. The Yellow Sea covers an area of about 400,000 square kilometers, and its deepest point is in the southeastern part of the Yellow Sea, about 140 meters. Oceanographers are accustomed to divide the Yellow Sea into the North Yellow Sea and the South Yellow Sea in accordance with its natural geography and other characteristics. The North Yellow Sea is a semi-enclosed sea between the Shandong Peninsula, Liaodong Peninsula and Korean Peninsula, with an area of about 80,000 square kilometers, an average depth of 40 meters, and a maximum depth of 86 meters on the southwest side of Baengnyeong Island. The oval-shaped semi-enclosed sea north of the Yangtze River mouth to Jeju Island line, called the South Yellow Sea, a total area of more than 300,000 square kilometers,

South Yellow Sea, the average depth of 45.3 meters, the maximum depth of water in the north side of Jeju Island, for 140 meters. The annual variation of water temperature in the Yellow Sea is smaller than that in the Bohai Sea, ranging from 15°C to 24°C. The salinity of the Yellow Sea water is also higher than that of the Bohai Sea. The salinity of the Yellow Sea water is also lower, 32 ‰. The Yellow Sea cold and warm currents converge, rich in aquatic products, especially the Bohai Sea and the Yellow Sea coastal terrain is flat, wide area, suitable for drying salt. For example, the famous Changlu Salt Area, the Shandong Salt Area west of Yantai and the Liaodong Bay area are all important salt producing areas in China. The line connecting Cape Qidong on the north coast of the Yangtze River estuary with the southwest corner of Jeju Island in South Korea is the demarcation line between the Yellow Sea and the East China Sea.

Crossing the Bohai Strait to the east and then to the south, the semi-enclosed Yellow Sea will present itself to us. It is a larger and deeper sea than the Bohai Sea. The Yellow Sea has long been the home of the Yellow River, and the Yellow River and other rivers have injected endless amounts of yellow-brown sediment into the Yellow Sea, making it the land-marginal sea that receives the largest amount of sediment in the world. The yellow-brown muddy sediment mixed with the blue transparent sea water, hundreds of miles of the sea border thus turned into a yellowish, the Yellow Sea so named. Nowadays, although the Yellow River has been diverted to the Bohai Sea, but the traces of history are not easy to be erased. What's more, the Yellow River water is still flowing indirectly to the Yellow Sea through the Bohai Sea, and the yellowish appearance of the Yellow Sea is not easy to change. Although the Yellow Sea is more open than the Bohai Sea, but it is still largely surrounded by the continent. 60 million to 70 million years ago, the Yellow Sea area is also a vast land, it also went through the first into a basin, and then become lakes, and then slowly evolved into the process of the ocean. After a period of time, due to the earth's climate change, the seabed of the Yellow Sea had resurfaced as a plain, when primitive human beings had already appeared and developed to the stage of using neolithic tools, a large area of the sea exposed as land, which became their activities to provide a more extensive place.

East China Sea China Zone Edit

The East China Sea has the China Zone, the Ryukyu Kingdom (a Japanese trusteeship rather than a Japanese territory) Zone, the Japan Zone, and the Korea Zone.

The East China Sea from the north of China's Yangtze River estuary to the north coast of South Korea's Jeju Island line, south of Nan'ao Island in Guangdong Province to the southern tip of the main island of Taiwan Province (a work through the Penghu to the Taiwan Dongshi Harbor) line with the South China Sea as a boundary, east to the Ryukyu Islands in Japan. The area is more than 770,000 square kilometers. Most of the continental shelf below 200 meters. Salinity is 31-32‰, and 34‰ in the east. The average sea water temperature is 9.2℃. The water temperature in the south is above 20℃ in winter. One of the world's famous fishing grounds, producing large yellowtail, small yellowtail, swordfish, cuttlefish and so on.

Located in the south of the Yellow Sea. The color is gorgeous and the scenery is beautiful. In its southeast, the huge Kuroshio warm current rushes in from the Pacific Ocean and winds along the northwest side of the Ryukyu Islands, as if draping the East China Sea with a blue ribbon of color. This color is a symbol unique to the Kuroshio water, which is exceptionally hot and salty, but the water quality is very poor and the organisms are extremely rare, thus revealing its blue-black appearance and earning it the title of Kuroshio. In the northwestern part of the East China Sea, the rolling Yangtze River pours from the mainland, the turbid muddy water to the sea to expand as much as possible. The central waters of the East China Sea are a greenish color due to the ****ing effect of the Kuroshio and the sediment of the Yangtze River. Scattered in the sea hundreds of islands, winding coast, towering cliffs, all of which dress up the East China Sea in a particularly enchanting.

South China Sea China Zone Edit

The South China Sea is the South China Sea within the nine-dash line, and there are many countries outside the line.

It is named for its location to the south of China. In recent times it has been translated from the English South China Sea to the South China Sea, but China still uses the South China Sea as its official name. However, places such as Singapore and Malaysia call it the South China Sea. From the East China Sea to the south through the narrow Taiwan Strait, you enter the surging South China Sea. The South China Sea is the deepest and largest sea in China and the third largest continental sea in the world after the Coral Sea and the Arabian Sea. The South China Sea is located between the Pacific Ocean and the Indian Ocean shipping key, in the economy, national defense are of great significance. The South China Sea is located in the south of China's mainland. North of the South China Sea is China's Guangdong, Guangxi, Fujian and Taiwan provinces, southeast to the Philippine Islands, southwest to Vietnam and the Malay Peninsula, the southernmost Tsangmamisha near Kalimantan Island. The vast South China Sea is connected to the Pacific and Indian Oceans through the Bass Strait, the Sulu Sea and the Strait of Malacca. It has the widest area of about 3.56 million square kilometers, equivalent to the size of 16 Guangdong provinces. The southernmost part of our country, Pu Mudan Shah, is more than 2,000 kilometers away from the mainland, which is farther than the distance from Guangzhou to Beijing. The South China Sea is also adjacent to China's deepest sea area, the average depth of about 1212 meters, the central abyssal plains in the deepest up to 5,567 meters, than the height of the mainland on the Tibetan plateau is also large. Most of the South China Sea is surrounded by peninsulas and islands, and the land area is very small compared with the ocean. Rivers injecting into the South China Sea are mainly located in the north, mainly the Pearl River, the Red River, the Mekong River and the Chao Phraya River. Since the sand content of these rivers is very small, the South China Sea, which is vast and deep, always appears turquoise or dark blue. The South China Sea is located in the low latitude region and is the warmest tropical deep sea in our sea area. South China Sea sea water surface water temperature is high (25 ℃ ~ 28 ℃), the annual temperature difference is small (3 ℃ -4 ℃), high temperature and high humidity all year round, long summer and no winter. The salinity of the South China Sea is the largest (35 ‰), the tide difference of 2 meters. The natural geographic location of the South China Sea, suitable for coral reproduction. On the seabed plateau, the formation of many beautiful coral islands, such as the Dongsha Islands, Xisha Islands, the Spratly Islands and Nansha Islands. The islands in the South China Sea were discovered and developed by our laborers a long time ago and are an inseparable part of our territory. The South China Sea is rich in aquatic products, producing sea turtles, sea cucumbers, oysters, horseshoe snails, tuna, red fish, sharks, prawns, barracuda, cuttlefish, squid and other tropical valuable aquatic products.

The South China Sea, also known as the South China Sea, is China's largest external sea. The area of the South China Sea is about 3.5 million square kilometers, equal to China's Bohai Sea, the Yellow Sea and the East China Sea, the total area of three times, second only to the Coral Sea in the South Pacific Ocean and the Arabian Sea in the Indian Ocean, ranking third in the world. The average depth of the South China Sea is 1,212 meters, but the deepest is 5,567 meters. If the Nanyue Hengshan stacked up to the South China Sea, the top of the mountain from the water there is nearly 700 meters away. The South China Sea is the offshore of the south of our country, which is bounded by the islands of Kalimantan and Sumatra in the south, the Central and South China Peninsula in the west, and the Philippine Islands in the east. The entire South China Sea is almost surrounded by continents, peninsulas and islands. The northeastern part of the South China Sea is connected to the Pacific Ocean through the Taiwan Strait and the East China Sea, the southern part is connected to the Java Sea, the Andaman Sea and the Indian Ocean through the Strait of Malacca, and the eastern part is connected to the Sulu Sea through the Bashi Channel. The South China Sea is located in the tropics, there are many coral pestles and coral islands in the sea, they are like a pearl set in the blue sea. These islands and pestles are collectively called the South China Sea Islands, which are divided into Dongsha Islands, Xisha Islands, Zhongsha Islands, Nansha Islands and Huangyan Islands. The Dongsha Islands are rich in aquatic products, such as sea turtles, cuttlefish and sea cucumbers. The Xisha Islands are a world of birds, with a thick layer of bird droppings piled up on the islands, which can be used as fertilizer. The Zhongsha Islands, unlike the other archipelagos, is still a group of coral pestles that have not been exposed to the water. The Nansha Islands is the largest archipelago in the South China Sea with the largest number of islands and pestles and is under the jurisdiction of Hainan Province; its southernmost point, Zengmu Dark Sand, is the southernmost point of China's territory. The South China Sea is a rich fishing ground, in which there are big yellowtail, small yellowtail, scallop, mackerel, cuttlefish, sea turtles, red fish and so on. Among them, the big yellow fish is an important seafood resource. The fish here never swim to foreign waters, but seem to be in love with their hometowns, and thus are known as "China's National Fish". The swiftlets in the South China Sea use seaweed and saliva to make nests, and such nests are the precious tonic bird's nests.

From the East China Sea to the southwest, across the Taiwan Strait, the turbulent waters into the crystal clear South China Sea. The South China Sea, bordering the mainland of China in the north and neighboring the Pacific Ocean and the Indian Ocean, is one of the largest and deepest oceans in China. It covers an area of about 3.5 million square kilometers. The South China Sea is a well-connected ocean. The South China Sea is not like the Bohai Sea, the Yellow Sea for the land surrounded by, it is more open than the East China Sea, there are many straits linked to the surrounding ocean and sea, the sea water in all directions, the transportation is very convenient.
