How big is the land area of the Bohai Kingdom, and where is the Bohai Kingdom now?

The Bohai State is now the northeastern region of China.

Part of the northeastern part of the Korean Peninsula and the Far East of Russia. Shangjing Longquan Mansion, the capital of the Bohai Kingdom, is located in what is now Ning'an City, Heilongjiang Province. During the heyday of the Bohai Kingdom, there were five capitals, fifteen prefectures and sixty-two prefectures, and its culture was deeply influenced by the culture of the Tang Dynasty and enjoyed the reputation of "the prosperous country of the eastern part of the sea".

The main cities of Bohai Kingdom include Zhongjing Xiande Mansion, Tokyo Longyuan Mansion, Xijing Yalu Mansion, and Nanjing Nanhai Mansion.

The name "Bohai Kingdom" comes from the title of "King of Bohai County" given by the Tang Dynasty. Some people believe that "Bohai" is a near-umlaut of "靺鞨". Some people believe that the Bohai Sea does not refer to a specific sea area, but is a general name for the eastern sea, and the Tang Dynasty named it "Bohai" after the sea to the east.

The founder of the Balhae Kingdom, Da Zuorong, is recorded in the historical records as being dependent on Goguryeo.

of the millet descent. In the 7th century A.D., it was a powerful tribal group in the southernmost part of the ancient ethnic group in Northeast China.

In order to consolidate the power of Zhenguo, Da Zuorong not only sent envoys to the Turks immediately after the founding of the country.

Alliance, and good access to Silla to the south.

Skillfully mediating between powerful neighbors, the power has grown rapidly in a few years.

The area of the Bohai Sea is 77,284 km.

Located between 37°07 40°56 north latitude and 117°33 122°08 east longitude, the Bohai Sea is a nearly enclosed inland sea, which is bounded by the Yellow Sea in the east by the line from the Laotieshan Cape of the Liaodong Peninsula through Miaodao to the Penglai Cape at the northern tip of the Shandong Peninsula.

The total length of the coastline is about 3,800 km. It is about 346 kilometers wide from east to west and 550 kilometers long from north to south. It covers an area of about 80,000 square kilometers and has an average depth of 18 meters.

According to the topography, the Bohai Sea can be divided into five parts: Liaodong Bay, Bohai Bay, Laizhou Bay, ** shallow sea basin and Bohai Strait.

Bohai Sea geology and landform

The Bohai Sea is basically surrounded by land, and only the Bohai Strait is connected to the Yellow Sea in the east, and the sediments are mainly silt and silt. There are three main bays around the Bohai Sea: Liaodong Bay to the north, Bohai Bay to the west, and Laizhou Bay to the south.

Due to the large amount of sediment brought by the Liaohe River, Luanhe River, Haihe River and Yellow River, the seabed is flat and the bait is abundant, and it is a large-scale marine aquaculture base in China. It is rich in prawns and yellow croaker. There are many salt pans along the coast, and the Changlu Salt Field on the west bank is the most famous.

The main islands are Miaodao Islands, Changxing Island, Xizhong Island, Chrysanthemum Island, etc. In 2007, rich oil was discovered on the bottom of the Bohai Sea, which has been exploited on a large scale.

The area of the Bohai Sea is 77,284 square kilometers. The Bohai Sea covers an area of 77,284 square kilometers, and more than half of the sea area is shallow below 20 meters. The Bohai Sea is located in the north temperate zone, with no scorching heat in summer and no severe cold in winter, with an average temperature of 10 degrees Celsius for many years.

The Bohai Sea is China's inland sea. It is surrounded by land on three sides, between Liaoning, Hebei, Shandong and Tianjin. The old iron triangle at the southern tip of the Liaodong Peninsula and Penglai on the north shore of the Shandong Peninsula face each other, like a pair of giant arms surrounding the Bohai Sea, and the shape of the shoreline is like a gourd.

The Bohai Sea communicates with the Yellow Sea through the Bohai Strait.

Protecting the Bohai Sea is a top priority

In recent years, a large number of studies have been carried out on the quality of the environment, such as ecosystems, environmental parameters, red tides, eutrophication, etc. In this paper, we discuss eutrophication, one of the most serious problems in the Bohai Sea, and analyze its causes, using years of water quality data from the Bohai Sea. I hope that the Bohai Sea can be well protected in the future.

However, with the development and utilization of marine resources, the resources and ecological environment of the Bohai Sea have been greatly damaged at the same time. The environmental quality of the Bohai Sea has deteriorated severely, which is manifested in obvious coastal pollution, expansion of pollution scope, weakening of ecosystem, degradation of ecological environment, red tide, and eutrophication. The environmental situation of the Bohai Sea has attracted the attention of ** and research institutions.

The area of the Bohai Sea is 77,284 square kilometers. The Bohai Sea is the largest inland sea, more than 10,000 square kilometers larger than the Ningxia Hui Autonomous Region, but it has been shrinking in size.

The average depth of the Bohai Sea is only about 18 meters (data from the mid-90s of the last century) can be said to be a very shallow shallow sea, the average depth of Qinghai Lake, the largest lake in China (21 meters), is deeper than the Bohai Sea, some geologists and hydraulic scientists believe that the average depth of the Bohai Sea will be lifted by 1 meter every 10 years, and its area is of course decreasing.

The reason why the Bohai Sea has become shallower and smaller.

The reason why the Bohai Sea has become shallow and smaller, the main reason is that the rivers along the coast have brought a large amount of sediment injection, among which the sediment sedimentation of the Yellow River is the most huge, before the 90s of the last century, the Yellow River carries about 1.6 billion tons of sediment every year, and the sediment deposition of the Bohai Sea creates a large tidal flat, resulting in the gradual shrinking of the Bohai Sea, from 1855 to the present, the Yellow River has been in the Dongying area of Shandong Province to create thousands of square kilometers of land.

The Bohai Sea is located at the northern tip of eastern Chinese mainland, and its geographical coordinates are between 37°07 -40°56 north latitude and 117°33 -122°08 east longitude. The Bohai Sea is surrounded by land on three sides, and between Liaoning, Hebei, Shandong, and Tianjin, it is also China's inland sea. The following is an introduction to the specific content of "Where is the Bohai Sea".

1. Inland Sea: The Bohai Sea is a nearly enclosed inland sea, which is part of the western Pacific Ocean, and the shape of the coastline of the Bohai Sea is like a gourd.

2. Composition: The Bohai Sea is composed of five parts: Liaodong Bay in the north, Bohai Bay in the west, Laizhou Bay in the south, shallow sea basin and Tanzao Gorge in the Bohai Sea.

3. Islands: There are more than 30 islands in the Bohai Sea, among which the larger ones are Nanchangshan Island, Tonji Island, Qin Island and Huangcheng Island, etc., collectively known as Miaodao Islands or Miaodao Islands.

4. Geology: The bottom of the Bohai Sea is flat, mostly sediment and soft mud, and the coast is divided into three types: silty and silty shore, sandy shore and bedrock shore.

Through the above article, I believe everyone knows the answer to the question "how many years can natural gas be used". So how big is the Bohai Sea? The Bohai Sea covers an area of 77,284 square kilometers, with a continental coastline of 2,668 kilometers, an average water depth of 18 meters, and a maximum water depth of 85 meters.

The Bohai Sea is China's inland sea, and the Bohai Sea is the northernmost offshore sea of China, the inland sea of the People's Republic of China, and also belongs to the category of internal waters. "Encyclopedia of China: Geography of China" contains: The Bohai Sea is composed of Liaodong Bay, Bohai Bay, Laizhou Bay and ** Sea Basin, and "Shandong Province Chronicles and Oceanography" also includes the Bohai Strait, a total of 5 parts.

The main rivers flowing into the sea are the Yellow River, the Liao River, the Luan River and the Hai River, with a total annual runoff of 88.8 billion cubic meters. The terrain is inclined from the coast to the ** and the strait, and the terrain is monotonous and gentle. There are remnants of paleocoastlines and paleochannels on the seabed.

The Bohai Sea is a Mesozoic and Cenozoic subsidence basin, and the basement is Precambrian metamorphic rocks. Quaternary sediments are up to 300,500 metres thick and are mainly terrigenous material. All three bays are covered with silty clay and clayey mud.

There are many fine silt, coarse silt and fine sand in the middle part. The northern part of the strait is gravel and shell fragments, while the southern part of the strait is fine-grained sediment.

The ancient state of the Bohai Sea was part of present-day Northeast China, the Northeast Korean Peninsula, and the Russian Far East.

The Bohai State was a regime in ancient Chinese history dominated by the Tata people, and its scope was equivalent to that of present-day Northeast China, the Northeast Korean Peninsula, and part of the Russian Far East.

In 698, Da Zuorong, the leader of the Su Mo Dynasty, was called "King Zhen" in Dongmu Mountain and established a regime. In 713, Tang Xuanzong canonized Da Zuorong as the "King of Bohai County" and awarded the governor of Kuhan Prefecture, with the name of "Bohai". In 762, the Tang Dynasty decreed that Bohai was elevated to a state.

In addition, there are other names such as "the country of the indigen", "the country of the Bohai eja", and "the country of Goryeo".

Its area corresponds to the area of present-day northeastern China, the northeastern part of the Korean Peninsula, and part of the Russian Far East.

The Bohai Kingdom (698-926) was a predominantly ethnic regime in ancient Chinese history, covering the area of present-day Northeast China, the Northeast Korean Peninsula, and part of the Russian Far East.

In 698, Da Zuorong, the leader of the Su Mo Dynasty, established a regime in Dongmu Mountain (now the southwest city of Dunhua, Jilin, or the ancient city of Longxi, the southeast city of Yanji, Jilin Province).

In 713, Tang Xuanzong canonized Da Zuorong as the "King of Bohai County" and awarded the governor of Kuhan Prefecture, with the name of "Bohai". In 762, the Tang Dynasty decreed that Bohai was elevated to a state. In addition, there are other names such as "the country of the indigen", "the country of the Bohai eja", and "the country of Goryeo".

After the founding of the People's Republic of China, the Bohai State was canonized by the Tang Dynasty, and the Tang Dynasty placed the Khan Prefecture in the Mudanjiang River Basin, where the Heishui Yan River lived, and set up the Khan Governor's Mansion, also known as the "Bohai Governor's Mansion", and its leader was named the Governor, and he was named the "King of Bohai County", known as the "Bohai Kingdom" in history; Its people call themselves "靺鞨", "靺鞨国" or "Bohai State". The Chinese historical book "New Tang Dynasty Book" calls it "the prosperous country of Haidong".

Shangjing Longquan Mansion is the first of the five capitals of Bohai State, which was built in the shape of Chang'an, the capital of the Tang Dynasty, and is located in Bohai Town, Ning'an City, Heilongjiang Province, China. Since the reign of King Wen of the Bohai Kingdom, Shangjing City has been the capital of the Bohai Kingdom for more than 160 years, and is the largest city in Northeast China and the center of political, economic, cultural, military and foreign exchanges of the Bohai Kingdom.

The ancient state of Balhae, this place included most of what is now Tohoku, the Korean Peninsula, and parts of Russia along the Sea of Japan.

The Tang Dynasty was a period of prosperity in all aspects of our country, during which our country had a vast territory, a prosperous economy, social stability, and the people lived and worked in peace and contentment, and at the same time, it also actively developed relations with neighboring countries. As a local ethnic regime at that time, the Bohai State was greatly influenced by the Tang Dynasty. In terms of territory and relationship, it is closely related to the two dynasties of the Tang Dynasty.

1. In 698 A.D. between the Tang Dynasty and the Bohai Kingdom, the leaders of the end of Su established the Kingdom of Yan and called the king of Zhen. In 713 AD, after Tang Xuanzong ascended the throne, he canonized the leader of Sumo as the king of Bohai County, ruled Kuhan Prefecture, and awarded the governor of Kuhan Prefecture. From then on, the Su Mo Jing regime took the Bohai Sea as its name and became a feudal state with autonomy within the territory of the Tang Dynasty.

In 762, the state of Jin was changed to the state of Bohai, and the capital was in the current Jilin Dunhua, and after four moves to Beijing, in 926, it was destroyed by the Liao state.

2. The Population and Territory of the Bohai State During the Tang Dynasty, the Bohai Kingdom became a part of the Tang Dynasty, and its territory was constantly expanding. Under the leadership of their leader, in its heyday, the Bohai Kingdom was centered on Jilin, with its territory stretching from the east coast of the middle and lower reaches of the Heilongjiang River in the north, the coast of the Tatar Strait facing Sakhalin Island, the south to the vicinity of Hamhung in Korea, the Sea of Japan in the east, and the vicinity of Baicheng and Da'an on the border between Jilin and Inner Mongolia in the west. In addition, they also imitated the model of the Tang Dynasty and established the five capitals, namely Shangjing Longquan Mansion, Zhongjing Xiande Mansion, Tokyo Longyuan Mansion, Xijing Yalu Mansion, and Nanjing Nanhai Mansion.

Since then, their population has grown from more than 100,000 to more than 3 million, and they have also won the reputation of "Bohai Shengguo".

Although the Bohai State was a small state with a minority regime, it not only prospered for a long time after its submission to the Tang Dynasty, but also promoted the continuous development of China's territory and made indelible contributions to the development of subsequent dynasties.

The ancient Bohai State was established by the ancestors of the current Manchus, and this place is now the northeast region, which was the ancient national power established in the north of the Tang Dynasty in China.

The ancient Bohai State was established in the Tang Dynasty, and its territory included most of the northeast of our country, south to Hamhung, North Korea, east to the Sea of Japan, and Sakhalin Island across the sea.

The Bohai State was a regime in ancient Chinese history dominated by the Tatar people, and its territory was part of today's Northeast China, the Northeast Korean Peninsula and the Russian Far East.

The area of the Bohai Sea is 77,284 square kilometers. The Bohai Sea is the northernmost coastal sea of China, the inland sea of the People's Republic of China, and also belongs to the category of internal waters. The total length of the coastline is about 3,800 km.

It is about 346 kilometers wide from east to west and about 550 kilometers long from north to south. It covers an area of about 80,000 square kilometers and has an average depth of 18 meters.

The Bohai Sea is a nearly enclosed inland sea, which is bounded by the Yellow Sea in the east by the line of the Laotieshan Cape of the Liaodong Peninsula through Larusongmiao Island to the Penglai Cape at the northern tip of the Shandong Peninsula.

According to the Encyclopedia of China - China Geography, the Bohai Sea is composed of Liaodong Bay, Bohai Bay, Laizhou Bay and ** Sea Basin. "Shandong Province Chronicles: Ocean Chronicles" also includes the Bohai Strait, a total of 5 parts.

Bohai Sea, located at the northern tip of eastern Chinese mainland, is located between 37°07 -40°56 north latitude and 117°33 -122°08 east longitude. The Bohai Sea is a Mesozoic and Cenozoic subsidence basin, and the basement is Precambrian metamorphic rocks.
