"Iron Lion's Head" is a well-known delicacy, so do you know the origin of the name of this dish? In fact, the name of Huaiyang's famous dish "Iron Lion Head" was obtained by combining the original "Lion Head" and "Cangzhou Iron Lion".
Speaking of "Cangzhou Iron Lion", it is known to everyone, its original name is "Cangzhou Iron Lion Zhenhai Roar", from this name can be seen, this is a statue of a god used in Zhenhai. In this way, it is a bit confusing, "Cangzhou Iron Lion Town Sea Roar" is located in the southeast suburbs of Cangzhou City, Hebei Province, about 16 kilometers away from the city, this is a place that has nothing to do with the sea, in such a place, how can there be a statue of the god of zhenhai? If we open the map, we can see that the Cangzhou Iron Lion Town Sea Roar is also about 70 kilometers away from the nearest coast, and who is it to "suppress" the Zhenhai God Beast in this position? In fact, Cangzhou Iron Lion Town Sea Roar was built to suppress the "Siren".
According to the records, the Cangzhou Iron Lion Town Hai Roar was built in 953 AD, when it was the third year of the Later Zhou Guangshun, so was it the wrong place to build the sacred beast used to "suppress" the Siren inland 70 kilometers from the coast?
In fact, it didn't, because this sacred beast was built on the seashore, and it hadn't moved since then, and the reason why it was so far away from the sea now was because the Bohai Sea had become smaller. The Bohai Sea is the largest inland sea in China, with an area of 77,000 square kilometers, but now the area of the Bohai Sea is much smaller than in ancient times. For more than 1,000 years, the coastline has been 70 kilometers away? Yes, and this is not surprising, because geologists believe that before 3,000 years, the area of the Bohai Sea could reach at least 100,000 square kilometers. The Bohai Sea has been shrinking since ancient times, and with the reduction of its area, further shrinkage has shown an accelerating trend, so if it continues, will the Bohai Sea disappear one day?
Yes, according to the current development trend, the Bohai Sea will indeed disappear, and now it is not too far from the day it disappeared, if you simply calculate according to the current trend, then it only takes two or three hundred years, the Bohai Sea will completely disappear from the map.
What caused the shrinking of the Bohai Sea? In fact, it is the sediment injection caused by the river. There are many rivers that flow into the Bohai Sea, such as the Haihe River, the Luan River, the LiaoHe River, etc., which will bring a large amount of sediment to the Bohai Bay, and the most important sediment carrier is the Yellow River. According to a statistic at the end of the last century, the Yellow River brought as much as 1.6 billion tons of sediment to the Bohai Sea every year, and in the past 60 years, the Yellow River alone has reclaimed thousands of square kilometers of land in Bohai Bay. So is there any promise of change in this situation? It is not too easy, because the loess sediment layers in some areas of the Yellow River Basin are too deep.
There is only one way to slow down, or even reverse, the trend of the Bohai Sea becoming smaller, and that is to reduce soil erosion along the rivers.
Reducing soil erosion is an easier said than done thing. According to the runoff of the river, the river can basically be divided into three types, namely seasonal rivers, intermittent rivers and constant flowing rivers, in these three types of rivers, the most difficult to control the soil erosion along the way is the seasonal rivers, and in the northern region of China, the rivers are basically seasonal rivers.
So why are seasonal rivers so difficult to manage? Because the flow of seasonal rivers has obvious seasonal characteristics, the most flow is the summer with the most precipitation, which is particularly easy to form floods at this time, and floods will inevitably lead to a large amount of soil erosion, which is why the rivers injected into the Bohai Sea will carry sediment, it can be seen that it is quite difficult to control soil erosion and slow down the trend of the Bohai Sea becoming smaller. So what if the trend of the Bohai Sea becoming smaller is not curbed?
If, after two or three hundred years, the Bohai Sea really disappears due to sediment deposition, then the impact on the entire northern region is very huge. One might think, isn't it a good thing that the sea has become a mulberry field? Of course not.
Once the Bohai Sea disappears, it will inevitably lead to changes in the climate in the north of China, affecting not only several provinces around the Bohai Sea. Once the Bohai Sea disappears, the water vapor obtained in China's northwest region and northeast China will be reduced, the drought problem will become more serious, and the drought will inevitably lead to the intensification of desertification, especially in Inner Mongolia and the northeast region, the climate in these areas is relatively arid, once the Bohai Sea disappears, the problem will become more serious. It can be seen that although the Bohai Sea is small, there is a huge difference between it and whether it has it or not, and these effects as we know it now are not all. So while soil erosion control is not an easy task, it is something we must do.
