崖柏（Thuja sutchuenensis Franch）是我国西南部大巴山地区的一种珍稀第三纪针叶残遗树种。在过去的世纪里，由于伐木，它几乎被消灭了。我们测量了大小和年龄结构，并解释了在各种地形背景和社区协会的物种的立场的更新动态。含T.四川崖柏群落有3种类型：（1）以四川崖柏为主的崖柏群落;（2）崖柏-栎-青冈群落以崖柏为主;（3）崖柏-铁杉-栎类群落，以崖柏-铁杉-栎类群落为主; sutchuenensis、铁杉（Tsuga chinensis）和刺栎（Quercus spinosa）。已建立的幼苗/树苗被发现在石灰岩裂缝，疤痕的悬崖面，悬崖边，倒下的日志，树冠间隙和林缘。径向生长速率为0.5- 1.1mm/a。它的生长形态被扭曲了。干扰后萌发能力强。霸王由于环境恶劣和岩崩的干扰，使它们几乎没有其他物种的竞争，因此它们在悬崖上茁壮成长。不耐荫，但耐胁迫。它的再生依赖于自然干扰。
A rare coniferous Tertiary relict tree species, Thuja sutchuenensis Franch, has survived in the Daba Mountains of southwestern China. It was almost eliminated by logging during the past century. We measured size and age structures and interpreted regeneration dynamics of stands of the species in a variety of topographic contexts and community associations. Forest communities containing T. sutchuenensis were of three types: (1) the Thuja community dominated by T. sutchuenensis, growing on cliffs; (2) the Thuja-Quercus-Cyclobalanopsis community dominated by T. sutchuenensis, Quercus engleriana and Cyclobalanopsis oxyodon, along with Fagus engleriana and Carpinus fargesiana, on steep slopes; (3) the Thuja-Tsuga-Quercus community dominated by T. sutchuenensis, Tsuga chinensis, and Quercus spinosa, on crest ridges. The established seedlings/saplings were found in limestone crevices, on scarred cliff-faces, cliff-edges, fallen logs, canopy gaps and forest margins. The radial growth rate was 0.5-1.1 mm per year. Its growth forms were distorted. It had strong sprouting ability after disturbances. The T. sutchuenensis population thrives on cliffs where there is little competition from other species because of harsh conditions and rockslide disturbances. It is shade-intolerant but stress-tolerant. Its regeneration has depended on natural disturbances.
