Abstract： The digitization of specimens is an important basis for the conservation and utilization of biodiversity. Through the integrated analysis of specimen data, it can provide data support in taxonomy, ecology, bioengineering, biological protection, food security, biodiversity assessment, human social activities and education and other aspects. At present, the development situation varies from country to country. In order to understand the current status of global specimen digitization work, as well as data sharing strategies and technology development trends, through comparison, provide suggestions for China’s specimen digitization work, this article summarizes the status of specimen digitization and platform construction in North America, South America, Europe, Africa, Asia and Oceania, and reviews the status and trends of specimen data sharing from data use agreements, new technologies and methods, and citizen science using. After comparison and analysis with the current situation in China, proposed work suggestions, including strengthening the construction of coordination mechanisms in the digital construction, management and dynamic update of specimens, ensuring the synchronization of physical resources and digital resource information; strengthening data collation and publishing, promoting data quality improvement, fully opening data use agreements, and reducing data use obstacles; strengthen the learning and introduction of new technologies, especially the application of open source software, machine learning and artificial intelligence technologies, which can play a role in rapid tag identification, automatic identification and attribute data extraction; strengthen regional and international cooperation to promote data. The integration and application of data products; promote the development of citizen science projects, and promote the development of field collection, indoor sorting, online error correction, and data product research and development.

Abstract：在进行多肉植物资源调查时，在我国山东发现一仙人掌科仙人掌属新记录种——匍地仙人掌[Opuntia humifusa (Raf.) Raf.]。该种具有独特的匍匐生长习性，叶状茎深绿色，无白霜，无针状刺，花黄色，与国内分布的仙人掌属其他物种区别明显。匍地仙人掌原产于北美洲，是仙人掌科为数不多的耐寒种类之一，现归化于中国山东省日照市五莲县，系目前发现的在我国野外分布最北的仙人掌科植物。该种可能于? 20 世纪? 50 年代在国家推广中药材时期引入种植，人类活动致使其种群逐渐扩散。同时，对匍地仙人掌与江苏报道的二色仙人掌之间的分类学问题进行了论述，并对将来匍地仙人掌在我国暖温带地区合理的开发利用进行了展望。
