摘要: 孑遗植物是区域生物多样性保育和恢复的重要成分。通过调查浙江天目山以孑遗植物为优势种的植物群落的种类组成和结构特征，分析了主要种群的种间关联性、种间相关性和生态位宽度，探讨树种间的相互关系及共生机制。结果表明：所有种对中，呈显著（P＜0.05）和极显著（P＜0.01）相关性的种对仅占20.77%，55.85%以上的种对呈负相关关系；孑遗落叶阔叶树种间多呈显著负相关关系，体现空间分布上的排斥性；蓝果树Nyssa sinensis，缺萼枫香Liquidambar acalycina，枫香Liquidambar formosana，香果树Emmenopterys henryi等长寿命孑遗落叶阔叶树种，与其他落叶树种间呈显著负相关关系，与常绿树种间呈显著正相关关系。作为先锋树种，孑遗落叶阔叶树种在干扰后可与短寿命树种如雷公鹅耳枥Carpinus viminea和化香树Platycarya strobilacea等一起侵入到裸地。当短寿命树种逐渐消退后，长寿命树种成为优势种，在群落演替上实现生态位互补；随着演替进程，孑遗落叶阔叶树种为具耐荫的常绿树种提供庇护场所，并长期处于群落超高层，在垂直空间上实现物种共存。图4表3参26

Abstract: Relict plants are an important component for protection and restoration of biodiversity in a region. To explore the symbiotic relationship and coexistence mechanism of evergreen，deciduous and coniferous trees in a relict deciduous forest of the National Nature Reserve of Mount Tianmu，Zhejiang，China，their floristic composition and community structure have been surveyed in 196 plots. The interspecific association，interspecific correlation，and niche breadth were determined using a correlation analysis and niche breadth analysis. Results indicated that species pairs with significant （P＜0.05） and highly significant （P＜0.01） differences accounted for 20.77%；whereas pairs that were negatively correlated comprised of 55.85%. The interspecific relationship among relict broadleaf tree species was significantly and negatively correlated with a mutually exclusive spatial distribution. The interspecific relationship between long-lived relict deciduous tree species，such as Nyssa sinensis，Liquidambar acalycina，Liquidambar formosana，or Emmenopterys henryi，and other deciduous tree species was significantly and negatively correlated，but was significantly and positively correlated with evergreen broadleaf tree species. Thus，relict deciduous tree species with tall stature were coexisted with other deciduous broadleaf tree species at succession serial and with evergreen broadleaf tree species at vertical spatial scale.［Ch，4 fig. 3 tab. 26 ref.］
