Endangered species conservation is an important part of biodiversity conservation, heavily helped by threatened species assessment guides. The assessment of threatened level has gradually evolved from being qualitative to quantitative with qualitative supplement. This paper reviews the research progress of the domestic threatened plant species quantitative assessment system, and introduces the mature IUCN Red List Assessment System, CITES Assessment System, and the National Natural Conservation Association Assessment System. Through this, we propose future development requirements of quantitative assessment criteria for threatened species should have the following characteristics: (1) a clear, unified, and reasonable definition of category setting, (2) quantitative, objective, and non-redundant criteria for endangered categories, (3) adaptation to different geographical range while simultaneously expressing threatened category over different ranges, (4) evaluation indicators contain the dynamic information of the species which can quantitatively analyze the change of the species through time. In addition, the domestic quantitative assessment system for threatened species should form a standardized outline with increased publicity to combine theoretical research with specific conservation actions. Lastly, China should adopt the widely-used endangered rating systems to assess species threatened level and integrate domestic biodiversity conservation work into the global scale.
