Abstract: National parks and national botanical gardens are important institutions for in-site and ex-situ conservation, respectively. National parks and botanical gardens can carry out conservation based scientific research, resource utilization, and nature education, as well as nature education based on conservation, scientific research and resource utilization. National parks and national botanical gardens are based on integrated conservation of nature education, which is the embodiment of public welfare, and also provides the basic conditions for the realization of other functions such as conservation. National parks and national botanical gardens need to establish a system of knowledge dissemination, scientific spirit, scientific culture, and scientific exploration for nature education with the theme of biodiversity conservation, deeply integrate plant culture with scientific culture, national culture and spirit of the times, explore a new mode of nature education for the popularization of high-end scientific research resources and conservation, effectively infiltrate science education in nature education, and promote the transformation of the audience′s values from "anthropocentrism" to "ecological holism". Nature education in national parks and botanical gardens plays an important role in the implementation of the Kunming-Montreal Biodiversity Framework and the construction of harmonious coexistence between man and nature.
