生态化学计量学在药用植物资源研究中的应用

Ecological stoichiometry and its application to medicinal plant resources

生态化学计量学是研究生物系统能量平衡和多重化学元素平衡的科学,是元素平衡对生态交互作用影响的一种理论,主要研究生态过程中化学元素的比例关系。文章介绍了生态化学计量学的概念、理论基础,综述了化学计量学在药用植物资源研究的现状。并且结合近年来生态化学计量学的最新研究进展,指出药用植物的生态化学计量学研究,应着重考虑药用植物化学计量特征与药用植物生长及次生代谢的关系、生物及非生物环境因子与药用植物生态化学计量特征的影响等方向。

Ecological stoichiometry is a study of the balance of biological system＇s energy and the balance of multiple chemical elements. It focuses on the relationship of the element ratio in ecological processes. In this paper, the concept and main theoretical ba- sis of ecological stoichiometry were introduced, and the status of stoiehiometry in medicinal plant resources was reviewed. According to the recent development of ecological stoichiometry, the future directions of ecological stoichiometry of medicinal plants could be the study of the relationship between stoichiometric characteristic and growth and secondary metabolism of medicinal plants, and the influ- ence of biotic （ or abiotic） factors on the stoichiometrie characteristic of medicinal plants.
