Abstract

Background: This is a new strategy of the “principle of plan as a whole” for the national botanical gardens’ constructive system in integrating plant conservation (both in situ and ex situ) for carrying out the Convention on Biological Diversity (CBD).

Aims & Conclusion: The Chinese national botanical gardens need an arrangement for coordinating the population size of the living plant cultivation for different functional plants, especially for endangered species, which is needed to protect more eco-types and populations. In China, other botanical gardens (BGs) carry out ex situ conservation for endangered plants as well. Moreover, some Chinese BGs have almost synchronizing to carry out ex situ conservation for endangered plants with the top BGs in the world. It is recognized that their achievements for ex situ conservation has had both their own strong points, and the problems also exist more or less as to the efficiency of ex situconservation. So that the point of view, the work of the Chinese national BGs should follow the standards of ex situconservation by the world top BGs is open to question.

Key words: Chinese national BGs, constructive system, ex situ conservation, population size for endangered plants, plan as a whole to other Chinese BGs, raising conservation efficiency
