The Forest Park is surrounded by mountains with lush forests and towering towers. It is a natural secondary broad-leaved forest with 900 species and varieties of vascular plants belonging to 500 genera and 176 families. There are 9 species of plants under state protection. Rivers and waterfalls in forests are rapidly drained from high to low to drive the flow of wet air around them. They are called natural oxygen bars because of their high negative ion content and over 9000 units per cubic centimeter.
