Abstract:Through the analysis of the present status of the development of botanical gardens,both domestic and international,with particular focus on the basis and advantages of the botanical gardens within the Chinese Academy of Sciences(CAS),the authors propose that in the future the scientific botanical gardens(which differ from common public gardens)should be constructed on the basis of the plant diversity investigation in key areas and ex-situ conservation of wild plant species,utilizing current key technologies to effectively preserve the diversity of botanic species as key technological means,taking the research on the scientific evaluation of plant resources function as the goal guidance,taking the reasonable utilization and R&D as strategic priority,taking the innovation of operational mechanisms as the basic guarantee.The establishment of special kinds of botanical gardens and specialized experimental platforms should be enhanced,and talented people in research,technology and management should be introduced and trained,open research on ex-situ preservation botanical resources should be conducted,and the producing of innovational achievements of independent knowledge property rights should be promoted,so as to lay down material foundation for aemerging bio-industry.
