ABSTRACT

In the fragile ecological environment of karst rocky desertification, exposed bedrock, vegetation such as forests and grasses are difficult to grow on a large scale, and regional ecological problems are difficult to continuously improve, seriously restricting the sustainable development of regional economy. Therefore, the governance of rocky desertification in karst areas is urgent. Karst biogenic algae can directly act on carbonate rocks and produce strong dissolution, accelerating soil formation. Therefore, studying the dissolution effect of algae on carbonate rocks is beneficial for further understanding the soil formation and vegetation restoration succession in karst areas, and provides a theoretical basis for controlling the fragile ecological environment in karst rocky desertification areas. At present, the research status and progress on the ecological restoration and weathering effects of algae on fragile karst ecosystems are not clear, and the summary of research results and problems is insufficient. On the basis of 71 relevant literature, this article focuses on sorting out the karst mechanism and ecological restoration potential of algae, revealing the achievements and shortcomings of current research on algae karst and ecological restoration.
