At present the mechanism of endangered species mostly confined to the morphology point of view, few physiological point of view of ecology, the lotus leaf fern Adiantum growth conditions of the study also stay in more qualitative analysis, there are few quantitative analysis of its optimum growth environment , The experimental use of morphological and physiological ecology of the idea and will use the components of the research methods, to be a long time to further explore their own independent development of plant taxonomy, morphology, physiology, ecology and other subjects the intrinsic link between , With a view to a new high on the survival of endangered species, adaptation and evolutionary mechanism.

目前对物种濒危机理的研究大都局限在形态学角度，很少有生理生态学角度的研究，对于荷叶铁线蕨生长条件的研究也多停留在定性分析上，很少有定量分析其最适生长环境，本实验采用形态学与生理生态学结合的思想，并将采用构件理论的研究方法，拟进一步探讨长期以来各自独立发展的植物分类学、形态学、生理学、生态学等学科之间的内在联系，以期能在一个新的高度上探讨濒危物种的生存、适应对策和进化机制。
