Abstract: Soil seed bank is an important part of the study of Karst Mountains, especially for the structure, function, and dynamics of vegetations in Karst region. This paper reviewed the methodologies and main subjects in the study of soil seed bank in this region. Based on a comprehensive analysis on related achievements, some problems to be urgently approached were presented. It was considered that the soil seed bank under dominant or constructive species in forest communities, the dynamic changes of soil seed bank under effects of invasive species and their affecting mechanisms on the species diversity of forest communities, and the roles of soil seed bank in vegetation restoration, etc., should be further studied, which would provide theoretical guidance for the studies on the soil seed bank and the practices in vegetation restoration in Southwest Karst region of China.
