Biodiversity is related to human survival and development, therefore protecting biodiversity has become a global hot topic of concern. The biological name is an identifier of biological identity, and using the correct biological name can help promote research on biodiversity conservation. At present, there are numerous plant name databases and software tools for processing plant names worldwide, but these plant name databases and software tools are scattered on various database websites or personal computers. Users need to spend a lot of time collecting these datasets and software tools, and also need to spend a lot of energy learning, using, and maintaining these datasets and software tools. Therefore, the learning and usage costs for users are relatively high. Here, we propose and implement a solution to address the aforementioned issues: we collected mainstream and freely available plant name datasets from around the world, integrated them into a massive plant name dataset, and then used the Solr search engine to index this massive, aggregated plant name dataset. Then, based on these plant name datasets, we conducted database design, system design, and system development, and finally developed an online integrated plant name indexing service system. This online plant name service system not only integrates mainstream plant name datasets worldwide, but also integrates free services such as plant name retrieval, plant name matching, plant name search, plant name resolution, and plant name API, thereby helping botanists better conduct research on biodiversity conservation.
