附生植物生理生态适应性研究进展

Advance in Researches on Eco-physiological Adaptability of Epiphytes

摘要:

附生植物是生活在其它植物体或残体上的特殊植物类群，大多生长于森林冠层，空间上远离地面土壤，在光能、水分和养分吸收方面具有明显的局限性。对附生植物的类群、分布、生态功能及对环境的适应性进行了综述，着重分析了附生植物在环境资源有限的生境中生长旺盛并占据重要生态位的原因。同时对今后的研究方向进行了展望，即更新附生植物数据库，明确附生植物水分和养分来源及利用策略，加强对附生植物开发利用及资源恢复重建的研究。

Abstract:

Epiphytes are special plant groups live on other plants or residues. Most of epiphytes grow in the canopy and far from the ground soil in the space, there are obvious limitations in the absorption of light, water and nutrients. The taxa, distribution, ecological function and adaptability to the environment of epiphytes were reviewed, and the reasons of its vigorous growth in habitat environment with limited resources and occupy the important niche were mainly analyzed. The future researches was prospected, such as update epiphytic database, make certain the sources and use strategies of water and nutrient, strengthen researches on exploitation and utilization and resource restoration and reconstruction.
