中山湿性常绿阔叶林根茎型附生蕨类植物克隆整合特性及其生态功能

中山湿性常绿阔叶林是云南哀牢山山体上部主要的原生森林植被，附生植物非常丰富，其中附生蕨类植物占优势，且绝大多数附生蕨具根茎型克隆生长的习性，目前有关对森林中附生蕨类植物的克隆整合特性的了解甚少。本研究以哀牢山中山湿性常绿阔叶林根茎型附生蕨类优势种为主要研究对象，运用野外原位观测和人工控制实验相结合的方法，并结合13C和15N稳定性同位素示踪技术，研究森林中根茎型附生蕨类植物的克隆整合特性，定量研究附生蕨类在水分胁迫或多资源斑块模拟生境中克隆整合格局及收益，探讨附生蕨类植物通过克隆整合适应异质生境的能力，阐明附生蕨类植物克隆整合的特性及其生态功能，为进一步探讨根茎型附生蕨类生态适应策略与机制提供理论基础，也为制定林冠生物多样性保护措施提供科学参考。通过本项目的研究，在国内外学术期刊上发表论文3-4篇，其中SCI 论文1-2篇，培养青年科技骨干1-2名。

Middle mountain moist evergreen broad-leaved forest is the major primary forest type in Ailao Mountain, Yunnan. There were rich epiphytic species including many epiphytic ferns in the forest. Most of epiphytic ferns have rhizome clonal growth feature. However, it is poorly understood on the clonal integration of epiphytic ferns. In this study, the clonal integration feature of epiphytic ferns will be conducted using field experiments and simulated habitats and utility 13C 15N stable isotope tracer technique. The adaptation of epiphytic ferns to heterogeneous habitats by clonal integration, and patterns and benefits of clonal integration of epiphytic ferns under water stress or simulated heterogeneous habitats of different resources will be studied. The clonal integration and its ecological functions, and habitat adaptation strategies and mechanism of rhizomatous epiphytic ferns will be revealed by the study. The information generated from this study will provide scientific basis for biodiversity and forest management. Based on this study, 3-4 academic papers (including 1-2 SCI papers) will be published and 1-2 graduate students will be grew up.
