The concept of "National Park" originated from the United States, the noun is translated from the English "National Park", it is said that the first American artist George Catlin (Geoge Catlin) put forward. In 1832, while traveling, he expressed deep concern about the effect of the expansion of the American West on Indian civilization, wildlife, and wilderness. "They can be preserved," he wrote, "if the government establishes a large park with some conservation policies... A national park, with people and wild animals, all in its natural state, reflecting the beauty of nature." Since then, it has been used in many countries around the world, and although the exact meaning varies, it basically refers to a form of the nature reserve.
