Abstract: With the rise of new powerful database system and network information technologies, the development of web-based management information system has rapidly increased in recent years. Based on standardized data from specimen records in China Weed Herbarium, a web-based management information system for weed specimens was developed. The structure and main function of the system are briefly introduced in this paper. In the mode of Browser/Server, the herbarium resources are shared on the Web. System users could obtain a wide variety of valuable information about herbarium records through Internet and administrators could implement the online management of weed specimens conveniently.
