The sea has always felt unfathomable and dangerous, but even so, many tourists still choose to travel to coastal cities and spend their holidays on the beach and on the coast.
And if you are afraid of the sea, there are also many people who choose lakes in the second place, such as Qinghai Lake, Qiandao Lake, Lugu Lake, etc., which are famous tourist attractions.
However, in our country, there is such a sea, although it is called "sea", but it is shallower than the lakes mentioned above, changing the stereotype of the public for the ocean in the past is "unfathomable", it is the shallowest ocean in China - the Bohai Sea.
It is the northernmost sea of our country, not only offshore, but also an inland sea of our country, with a length of 550 kilometers, a width of 346 kilometers, and an area of 80,000 square kilometers.
It is surrounded by land on three sides, and is surrounded by 13 cities from the three major provinces of Liaoning, Tianjin, Hebei and Shandong, and a major city, only the eastern strait is connected to the Yellow River.
Regarding the depth of the Bohai Sea, after exploration, it was found that its deepest place was at the old Tieshan waterway of the Bohai Strait, reaching a depth of 86 meters. This number may surprise many people, and some of the shallow shoals along the coast are deeper than this number. And it is actually the deepest depth of the Bohai Sea.
So what is the average depth of the Bohai Sea? Only 18 meters. It should be known that the average water depth of Qinghai Lake is 21 meters, which shows how shallow the shallowest part of the Bohai Sea is, which lowers the average level.
As for the Yellow Sea next to the Bohai Sea, the average water depth is 90 meters, and it is needless to say that the number of 349 meters in the East China Sea is in line with the psychological expectations of ordinary people.
However, in terms of area, the Bohai Sea can be regarded as the largest inland sea in China, reaching 7.7 square kilometers, but in recent years, the area of the Bohai Sea has been shrinking, coupled with its own is not deep, which has led many people to think that it has the possibility of completely disappearing within 300 years.
Because according to expert surveys, the average water depth of the Bohai Sea will be raised by 1 meter every 10 years, and the aforementioned area is also shrinking, so that the "disappearance rumors" of the Bohai Sea are intensifying.
In recent years, the Bohai Sea has become smaller and shallower, mainly because the rivers along the coast have brought a large amount of sediment. Because of China's high terrain in the west and low in the east, the Bohai Sea in the east receives infusions from more than 40 rivers every year, such as the Yellow River and the Liao River, which carry a large amount of sediment and an annual land area of up to 20 square kilometers.
This is inevitably frightening, because once the Bohai Sea disappears, it will have a drastic impact on China's northern climate, resulting in a more serious drought situation in China's North China Plain, Shandong Peninsula and even Jilin and Inner Mongolia.
If you can compare satellite images taken decades ago, it is clear that the area of the Bohai Sea has rapidly "shrunk" in a few decades. Action to control the sediment is therefore imperative.
But even so, the Bohai Sea has still created 13 coastal port cities in China, developed local maritime transportation, and promoted the economic development of surrounding cities.
At the same time, a number of bohai rim tourist cities have also emerged around, and the popularity of the Bohai Rim self-driving tour route in the tourism industry is also quite high. On the north shore of the Bohai Sea is a red beach that "burns" like a flame, and on the west bank is the bright Tianjin Port, and there are rugged reefs along the coast, and there are islands guarding the "gate".
When winter comes, there is also a unique phenomenon of sea ice in the Bohai Sea, with white and crystalline white crushed ice floating on the surface of the sea, like a white crushed diamond scattered on the sea.
As for whether the Bohai Sea will disappear, I believe that there are its own countermeasures, and for the beautiful scenery around the Bohai Sea, tourists can rest assured to enjoy it, because in any case, the scene that is displayed in front of them at this moment is the most real.
