legend

It is said that when the monkey king fought Erlang God, he chose two islands. When he passed the Bohai Sea, he accidentally broke the pole carrying the two islands. Among the islands in the sea, one is the sea Cat Island, and the other is the Snake Island. In a rage, the monkey king settled the two islands and formed two islands, namely, the sea Cat Island and the Snake Island.

formation

Shedao was formed by long-term natural changes in a specific geographical environment. According to the analysis of its rock strata and lithofacies, it was about 1 billion years ago. Shedao and Liaodong Peninsula were originally linked together. The Mesozoic Yanshanian movement 100 million years ago and the Himalayan orogeny 10-20 million years ago produced the Liaohe fault and the Bohai Sea subsidence. At this stage, the Snake Island was formed in the Bohai Sea by the compressed boulders. At that time, Shedao was very small, only a fraction of what it is now. It took several years for the earth's crust to keep rising to form what it is now. Over the years, the Snake Island has formed a food chain in which snakes eat birds, birds eat insects, insects eat plants, and plants use bird manure as fertilizer, forming a complete ecosystem with snakes as the center. In the mid-1950s, according to the survey and statistics of Chinese scientists, there were 50000 to 100000 vipers on the Snake Island at that time. But in June 1958, a big fire broke out on the Snake Island, burning for four or five days in a row, and the whole plant on the Snake Island was almost reduced to ashes. A large number of snakes were burned and roasted, and the snake resources were seriously damaged. After reform and opening up, Snake Island and old fellow iron mountain were listed as national nature reserves. Special management organizations were set up, and observation stations were set up on Snake Island. Scientific observation, analysis and utilization and protection of the black Viper were carried out on the island of snake. Scientific research shows that the snake venom produced by agkistrodon halys Pallas is a valuable medicinal resource, and its medicine has good therapeutic effect on various neuromuscular, blood circulation and other diseases.

As for the origin of snakes on Shedao, the research shows that the snakes on the island came from the mainland, but they did not cross the sea from the mainland, nor were they brought to the island by fishing boats, but were the result of the changes of sea and land during the geological period. About several hundred million years ago, the sea level was much higher than today's. Liaodong Peninsula and Shedao were submerged in the sea. By 400 million years ago, this area began to land, Liaodong Peninsula and Shedao began to gradually expose to the sea. Later, after several crustal movements and sea level rise and fall, the current situation of Shedao was finally achieved. At present, the population of Agkistrodon halys in Shedao has increased from about 9000 at the beginning of the establishment of the reserve to more than 20000, and new achievements have been made in snake protection and scientific research.
