摘要
【目的】近年来,通过电子商务平台获取境外珍贵的多肉物种资源已成为一种重要渠道,大量濒危物种通过第三方物流方式非法流入我国。甄别濒危物种并梳理出多肉物种资源重点查验名单,能够为物种资源查验尤其是植物多肉类濒危物种查验提供参考。【方法】以跨境多肉物种资源交易的热门平台"多肉之家"为研究对象,基于网络爬虫技术平台,获取电商多肉植物926条种类数据,并对数据进行筛选和归类分析。【结果】"多肉之家"平台上交易的多肉植物共涉及23科878种,其中包含18种CITES附录Ⅰ以及120种CITES附录Ⅱ濒危物种,约占16%。进一步对濒危植物进行归类分析发现,濒危植物中仙人掌科和大戟科多肉植物种类最多,分别为66和36种,两者占总计濒危植物种类的74%。【结论】网络爬虫技术在获取电商类平台的交易植物的种类数据上具有较好的实用性。
【 Aim】 In recent years,obtaining foreign valuable succulent plants through the e-commerc.e platiorm has become an im-portant 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 re-sources ,especially for inspection of endangered succulent plants.【 Method】 Based on the w,e b crawder technology platfomi,926 cat-egories of data on succulent plants wee 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 Appendix I and 120 en-dangered species of CITES Appendix n . 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 re-spectively 66 and 36, accounting for 74% of the total endangered plant species.【 Conclusion】 Results indicate that the w,e b crawder technology platform has good feasibility in obtaining the species data in the e-commerce platform of plant trading.
