Abstract:Ecological stoichiometry theory was first used in the research of aquatic ecosystem, but in recent 20 years, a large number of researches associated ecological stoichiometry particularly plant N/P stoichiometry under global change have been carried out in the terrestrial ecosystem, which greatly enriched and enhanced our understanding of the processes of terrestrial plants, including ecosystems ecological processes. The research status of terrestrial plant ecological stoichiometry in the context of global change was reviewed. At the same time, taking the 90th anniversary of South China Botanical Garden, Chinese Academy of Sciences as an opportunity to summarize our research work on the ecological stoichiometry of subtropical forest plants in South China, and further analyze some existing problems and propose the development focus on future research, with a view to promote and push research in the field of ecological stoichiometry in our garden or China.
