摘要
Algae play a crucial role in the evolution of earth and life on earth,and also the cycle of matter.With its unique physiological and ecological properties and strong reproductive capacity,algae deeply influence the formation and development of karst.During the formation of tufa landscapes in Huanglong Scenic Area,the coloration,precipitation and corrosion of algae acting on tufa always concordantly exist.The algae living in water add gay colors to the tufa landscapes.The carbonate precipitation facilitated by algae is an important biological cause of the formation of tufa.As the external environmental conditions change,for instance,the shortage of karst water in tufa landscapes,the coloration and powerful corrosion of algae will stand out,which will badly affect the development and visual value of tufa landscapes.By studying the functions of algae in the tufa landscapes of Huanglong Scenic Area,this research was to provide scientific basis for the future study and protection of tufa landscapes.
