Abstract:

According to framework of international evaluation index system of plant species extinction risk and evaluation criteria, 69 wild plant species with tiny populations in China were assessed for their endangered levels based on their adaptability to habitat by using the analytic hierarchy process and survey analysis combined with scientific experiments. An evaluation index system was established and with the system all 69 species were evaluated as endangered species, among which 37 species were highest endangered (I level), 13 species higher endangered (II level), and 19 species highly endangered (III level).

Key words: tiny population, wild plants, endangered levels, evaluation index system
