A database of seed plants on taxonomy, geography and ecology in the Qinling-Daba Mountains and adjacent areas

The Qinling-Daba Mountains span subtropical and warm temperate zones and are one of the most remarkable biodiversity hotspots in China. Establishing a complete checklist of seed plants organized by nature reserves in the Qinling-Daba Mountains and adjacent areas is an important basis for managing and utilizing plant resources. First, we collected seed plant species data from published checklists representing 58 nature reserves in the Qinling-Daba Mountains and adjacent areas; second, we comprehensively and systematically sorted and integrated these data; third, we proofread and revised the data with the help of the R language and Flora of China dataset ; and finally, we set up a seed plant database containing 96148 records, including the name, order, family, genus, life form, and endemism of each species for the entirety of the Qinling-Daba Mountains. The database contains 9491 species of seed plants belonging to 1729 genera, 211 families, and 59 orders, accounting for 39% of China’s seed plants.

秦岭-大巴山（Qinling-Daba Mountains）横跨亚热带与暖温带，是中国最具代表性的生物多样性热点区域之一。建立秦岭-大巴山及周边区域按自然保护区分类的完整种子植物名录，是管理与利用植物资源的重要基础。本研究首先从秦岭-大巴山及周边58个自然保护区的已发表名录中收集种子植物物种数据；其次对这些数据进行全面系统的整理与整合；第三，借助R语言（R language）和《中国植物志》(Flora of China)数据集对数据进行校对与修订；最终构建了覆盖秦岭-大巴山全域的种子植物数据库。该数据库共计包含96148条记录，每条记录涵盖物种名称、目、科、属、生活型及特有性信息。数据库共收录种子植物9491种，隶属于59目、211科、1729属，占中国种子植物总物种数的39%。
