全球变化背景下陆地植物N/P生态化学计量学研究进展

Research Progress of Terrestrial Plants N/P Ecological Stoichiometry under Global Change

摘要:

生态化学计量学理论最早应用在水生生态系统的研究中，但最近20年来在陆地生态系统中也开展了大量的相关研究，特别是关于全球变化背景下陆地植物N/P生态化学计量学方面的研究得到很大的发展，极大地丰富和提升了我们对陆地植物包括生态系统生态过程的认识。就全球变化背景下陆地植物生态化学计量学的研究现状进行了综述，同时以中国科学院华南植物园90周庆为契机，总结我们关于南亚热带森林植物生态化学计量学的研究工作，进而分析当前存在的一些问题并提出今后研究的发展重点，以期促进和推动我园和我国生态化学计量学相关领域的研究。

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.
