Abstract： Karst Tiankengs are one type of negative topography that are of high value for conservation, providing habitats and breeding unique biological resources not found in the surrounding landscape. In recent years, the studies on karst Tiankeng in China has increased our understanding of diverse geological and ecological questions, from the formation and evolution of Tiankeng to species diversity. Based on a systematic review of the previous studies on karst Tiankeng, we reviewed the main advances and new findings, and addressed key topics for future studies. These key findings and topics include the distribution, evolution and vegetation ecology of Tiankeng. We also propose five key areas of focus for future studies: (1) the causes of Tiankeng formation and its vegetation ecology in systematicness, large scale and multidisciplinary collaboration; (2) the effect of biological resources in Tiankeng on ecological restoration of desertification area outside Tiankeng; (3) the distribution of soil microbial community and their interaction with plants in Tiankeng; (4) the impact of environmental change on karst Tiankeng ecosystem; (5) the assessment of the impact of tourism development on Tiankeng vegetation ecology.
