Through analysis of the historical and present development of botanical gardens, both domestic and international, with particular focus on botanical garden practices within the Chinese Academy of Sciences (CAS), the authors propose that science-based botanical gardens (which differ from common public gardens), should be founded on plant diversity inventory and ex-situ conservation of wild plant species. Efforts should be directed to rarer species from biodiversity-rich areas and biodiversity hotspots, utilizing cutting-edge technologies to effectively preserve germplasm in living collections. Science-based botanical garden management should be directed by sound scientific evaluation of plant resources and guaranteed by innovative operational mechanisms. Science-based botanical gardens should also emphasize the establishment of identifiable and specialized living collections, research platforms and recruitment of qualified experts. In addition to curating living specimens, science-based botanical gardens should pursue research and development of new plant varieties or patents based on their plant collections, thus providing continual support to bio-industry. 展开更多
