[Aim] We classified, introduced, compared, and evaluated important invasive alien species databases and plant pest databases in a global scale to clarify the progress of database construction in biosecurity and plant protection in order to know the effectiveness of database construction in China.[Method] We classified the databases according to the species' geographic range, taxa, and databases' characteristic functions. We did a brief introduction to the main functions of important databases. We set up a multi-criteria evaluation system to compare our databases with high-quality international databases and then analyzed our databases' essential functions that need to be improved urgently.[Result] We classified the databases global, regional, national, provincial, specific taxa, and other types. The comparison showed that the existing databases in China had played an essential role in supporting the detection and monitoring of invasive alien species and the phytosanitary enforcement of import and export plants. However, there are still gaps compared with the world-class databases, mainly reflected in low data quality, insufficient data mining, and weak popular science functions.[Conclusion] We recommend that related ministries should provide more excellent support for the construction, long-term maintenance, optimization, integration, and international promotion of relevant databases in China. We suggest the existing databases need to perfect data and functions, improve practicality and ease of use, which will provide strong support for scientific research and create favorable conditions for popular science, public participation, and citizen science.
