摘要:

低山丘陵热性常绿阔叶灌丛是热性常绿阔叶灌丛中分布面积最大的类型。于2011-2019年调查其中3个常见群系, 共获得样方325个, 采用中国经典植被分类与数量分类相结合的方法划分群落类型, 对各分类单位的群落结构、分布、生境等特征进行定量描述。主要结果: (1)岗松(Baeckea frutescens)灌丛分布范围为18.4°-25.9° N, 105.2°-118.3° E, 海拔0-1 340 m; 101个样方记录到维管植物170种, 隶属52科124属, 热带分布属占种子植物属数的79.5%, 常绿阔叶木本植物的重要值为90%; 该群系划分为5个群丛组, 7个群丛。(2)桃金娘(Rhodomyrtus tomentosa)灌丛分布范围为18.2°-26.2° N, 104.3°-118.8° E, 海拔4-700 m; 205个样方记录到维管植物373种, 隶属79科241属, 热带分布属占种子植物属数的70.2%, 常绿阔叶木本植物的重要值为85%; 该群系划分为4个群丛组, 24个群丛。(3)番石榴(Psidium guajava)灌丛分布范围为22.1°-27.1° N, 101.7°-113.8° E, 海拔100-900 m; 19个样方记录到维管植物83种, 隶属38科76属, 热带分布属占种子植物属数的71.8%, 温带分布属占19.7%, 常绿阔叶木本植物的重要值为81%; 该群系划分为4个群丛组, 5个群丛。研究表明, 岗松灌丛和桃金娘灌丛在群落结构、生境特征和发生起源方面较为相似, 两者均为本土天然次生灌丛, 其分布区有较大重叠; 番石榴灌丛是外来种为优势的群落, 对本土植被生境的侵占较为严重, 应在今后的监测研究中给予重视。

Abstract:

Tropical evergreen broadleaf shrublands in low mountain and hilly areas represent the most extensive shrubland type in China. We surveyed 325 plots between 2011 and 2019 across three dominant vegetation alliances to classify community types and quantify their floristic composition, structure, and distribution. Using classical Chinese vegetation classification and quantitative analysis, we identified three major shrubland types. (1) Baeckea frutescens shrublands occur from 18.4° to 25.9° N and 105.2° to 118.3° E, at altitudes of 0-1 340 m. In 101 plots, we recorded 170 vascular plant species in 52 families and 124 genera, with 79.5% of seed plant genera showing tropical affinities; evergreen broadleaf woody species accounted for 90% of total importance value. This alliance comprises 5 association groups and 7 associations. (2) Rhodomyrtus tomentosa shrublands span 18.2° to 26.2° N and 104.3° to 118.8° E, at 4-700 m altitude. In 205 plots, we recorded 373 vascular plant species across 79 families and 241 genera, with 70.2% tropical genera and 85% importance value for evergreen broadleaf woody species. This alliance includes 4 association groups and 24 associations. (3) Psidium guajava shrublands, occurring between 22.1° to 27.1° N and 101.7° to 113.8° E, at 100-900 m altitude, were recorded in 19 plots, comprising 83 vascular plant species across 38 families and 76 genera, with 71.8% tropical seed plant genera, and an 81% importance value for evergreen broadleaf woody plants. This alien-dominated alliance forms 4 association groups and 5 associations. Baeckea frutescens and Rhodomyrtus tomentosa shrublands share similar community structures and habitat preferences, representing native, natural secondary communities with overlapping ranges. In contrast, Psidium guajava shrublands, dominated by alien plants, pose a growing threat to native vegetation and require urgent monitoring. Our results offer a comprehensive baseline for understanding the structure, function, and dynamics of tropical shrubland ecosystem in China.
