[Aim] In recent years, obtaining foreign valuable succulent plants through the e-commerce platform has become an important channel and a large number of endangered species illegally were introduced into China through third-party logistics. Screening out endangered species and proposing a key checklist of succulent plants can provide a reference for the identification of species resources, especially for inspection of endangered succulent plants.[Method] Based on the web crawler technology platform, 926 categories of data on succulent plants were obtained from the popular internet trade platform "succulent plant house" in China. The data were then screened and classified according to CITES.[Result] There were 878 species of succulent plants belonging to 23 families from the data obtained from the "succulent plant house", which included 18 endangered species of CITES AppendixⅠ and 120 endangered species of CITES AppendixⅡ. The endangered species acconted for 16% of all the succulent plants imported. Results show that the most endangered plant species belonged to Cactaceae and Euphorbiaceae. The numbers of species in both families were respectively 66 and 36, accounting for 74% of the total endangered plant species.[Conclusion] Results indicate that the web crawler technology platform has good feasibility in obtaining the species data in the e-commerce platform of plant trading.
