This paper presents a comprehensive analysis of digitized specimen data and relevant literature to investigate the vascular plant diversity in Guangzhou City, China. Specimen data were collected from various sources, including the China Digital Herbarium (CVH), the National Specimen Resource Sharing Platform (NSII), Global Plants on JSTOR, and the Global Biodiversity Information Facility (GBIF). Following data standardization, the study identified 41,890 vascular plant specimens, encompassing 248 families, 1563 genera, and 4536 species, including subspecies and cultivated plants. Among them, the native plants of Guangzhou city accounted for 60.6% of the species. The temporal analysis identified three distinct peaks in specimen collection: 1916-1920, 1928-1936, and 1950-1964. Collection activities were primarily concentrated between the months of April and November. The distribution of collected specimens exhibited significant variation among different species, with families such as Fabaceae, Poaceae, and Myrtaceae having the highest number of specimens. Similarly, genera such as , , and were well-represented. The most frequently collected species included , , and . Remarkably, 21 species had specimen counts exceeding 100. Unfortunately, approximately three-quarters of the species had fewer than 10 recorded specimens. Alarmingly, 1220 species were represented by only one specimen. Geographically, the majority of specimens originated from the former suburbs of Guangzhou, Conghua Delta Mountain, and Liuxi River areas, while other regions had limited representation. In terms of specimen collections, the Herbarium of South China Botanical Garden of the Chinese Academy of Sciences (IBSC) recorded the highest number of specimens (13,828 specimens), followed by the Tree Herbarium of South China Agricultural University (CANT; 3869 specimens) and the Herbarium of Sun Yat-sen University (SYS; 3654 specimens). The collection history in Guangzhou spans nearly 300 years and can be broadly divided into two distinct periods. The first period extends from the late 13th century to 1949, primarily encompassing the collection efforts of foreign visitors in Guangzhou, and represents the pioneering phase of plant taxonomy research in China. The second period, from 1949 to the present, is characterized by extensive investigations and collection activities conducted by local scholars, with a specific emphasis on native plant resources. By meticulously organizing and verifying information derived from historical documents and specimens, the paper effectively summarizes the plant collection and research history of Guangzhou, providing detailed profiles of the key collectors. These findings furnish reliable historical reference materials for the study of plant taxonomy and diversity in Guangzhou.
本文对数字化标本数据及相关文献进行了全面分析，以调查中国广州市的维管植物多样性。标本数据来自多个来源，包括中国数字植物标本馆（CVH）、国家标本资源共享平台（NSII）、JSTOR上的全球植物数据库以及全球生物多样性信息网络（GBIF）。经过数据标准化处理后，该研究识别出41,890份维管植物标本，涵盖248科、1563属和4536种，包括亚种和栽培植物。其中，广州市的本土植物占物种总数的60.6%。时间分析确定了标本采集的三个明显高峰：1916 - 1920年、1928 - 1936年和1950 - 1964年。采集活动主要集中在4月至11月之间。所采集标本的分布在不同物种间呈现出显著差异，豆科、禾本科和桃金娘科等科的标本数量最多。同样，诸如 、 和 等属也有较多代表。最常被采集的物种包括 、 和 。值得注意的是，有21个物种的标本数量超过100份。遗憾的是，约四分之三的物种记录标本数量少于10份。令人担忧的是，有1220个物种仅由一份标本代表。在地理分布上，大多数标本来自广州的原郊区、从化三角洲山区和流溪河地区，而其他地区的代表性有限。在标本采集方面，中国科学院华南植物园标本馆（IBSC）记录的标本数量最多（13,828份标本），其次是华南农业大学树木标本馆（CANT；3869份标本）和中山大学标本馆（SYS；3654份标本）。广州的标本采集历史跨越近300年，大致可分为两个不同时期。第一个时期从13世纪末到1949年，主要包括外国访客在广州的采集工作，代表了中国植物分类学研究的开创阶段。第二个时期从1949年至今，其特点是当地学者进行了广泛的调查和采集活动，特别强调本土植物资源。通过精心整理和核实来自历史文献和标本的信息，本文有效地总结了广州的植物采集和研究历史，提供了关键采集者的详细资料。这些发现为广州植物分类学和多样性研究提供了可靠的历史参考资料。
