Algae and lichens may directly colonize and live on the surface of carbonate rocks. Through biochemical and physical processes, they bore and corrode the substrate, thus producing distinct biokarst microforms. The development of these microforms, moreover, has close relationship with the mositure and heat on the surface of carbonate rocks, microenvironments of different ge-omorphological positions, the cover-degree of vegetation and even different climate zones. In order to open new ideas about the study of biokarst, the prospects of the study of biokarst microforms are discussed and forecasted.
