摘要： 雅鲁藏布大峡谷国家级自然保护区地处青藏高原东南缘, 因其独特的地形与气候条件, 有着全球最完整的山地植被垂直带谱, 其植被发育完整、独特, 多样性丰富。以往保护区内的植被研究多聚焦中低海拔下的森林和原生植被, 对高海拔的灌丛、草本植被及次生植被等关注不足, 已有的植被调查结果和分类系统未能全面反映该区域的植被多样性。本研究基于2019–2025年在保护区范围内设置的493个样地、590个样方、16,648个样点的调查数据及文献资料, 依据《中国植被分类系统修订方案》分类原则, 编制了该保护区的植被分类系统, 并将其植被类型划分为5个植被型组、20个植被型、34个植被亚型、162个群系。和以往研究资料相比, 本文新增了75个群系类型记录, 其中森林27个、灌丛25个、草本植被20个、沼泽与水生植被3个, 主要有印度锥(Castanopsis indica)林、高山柏(Juniperus squamata)林、高山栎(Quercus semecarpifolia)林、大叶水榕(Ficus glaberrima)林、墨脱紫菀(Aster motuoensis)灌丛、以柯属(Lithocarpus)植物为建群种的常绿阔叶林、分布于高海拔段的杜鹃花属(Rhododendron)灌丛与杂类草高寒草甸、次生植被如马蹄荷(Exbucklandia populnea)林与粗壮琼楠(Beilschmiedia robusta)林等。新群系类型的发现与植被分类系统的完善展示了保护区丰富的植被多样性与植被类型本底资料, 可为后续植被研究、生物多样性保育和生态保护提供基础框架和参考。

Abstract

Aims: The Yarlung Zangbo Grand Canyon National Nature Reserve, characterized by unique topographic and climatic conditions, harbors the world’s most complete montane vertical vegetation spectrum and supports highly diverse, distinctive, and well-developed vegetation. Previous studies in the Reserve have mainly focused on forest and primary vegetation at low and middle elevations, whereas high elevation shrublands, herbaceous vegetation, and secondary vegetation have received much less attention. As a consequence, existing vegetation surveys and classification systems have not fully reflected the vegetation diversity of the region. This study aims to compile a more complete vegetation classification system for the Reserve and to clarify its newly recorded alliances. 

Methods: Based on surveys of 493 plots, 590 quadrats, and 16,648 survey points conducted within the Reserve, together with previous literature, and following the principles of A revised scheme of vegetation classification system of China, we compiled a vegetation classification system for the Reserve. 

Results: The vegetation of the Reserve was classified into 5 Vegetation Formation Groups, 20 Vegetation Formations, 34 Vegetation Subformations, and 162 Alliances. Compared with previous studies, 75 Alliance types were newly recorded (27 for forest types, 25 for shrubland types, 20 for herbaceous vegetation types, and 3 for swamp and aquatic vegetation types). Representative newly recorded types include Castanopsis indica Forest, Juniperus squamata Forest, Quercus semecarpifolia Forest, Ficus glaberrima Forest, Aster motuoensis Shrubland, evergreen broadleaf forest dominated by Lithocarpus species, high-elevation cold-temperate evergreen broadleaf shrubland dominated by Rhododendron species and forb alpine meadow grassland, secondary vegetation types such as Exbucklandia populnea Forest and Beilschmiedia robusta Forest. 

Conclusions: This study further develops the vegetation classification system of the Reserve, resulting in a more complete classification scheme, including more fully documented forest vegetation as well as previously underrepresented shrublands and herbaceous vegetation at high elevations, and secondary vegetation. Together with the newly recorded alliance types, this provides a more complete account of the abundant of vegetation diversity as well as the baseline data on vegetation types in the Reserve, offering a scientific basis for future vegetation research, biodiversity conservation and ecological protection in the region.
