Abstract

Lianas are a crucial component of karst seasonal rainforests, yet research on them has predominantly focused on non-karst regions. Consequently, their abundance and species richness remain relatively understudied within karst ecosystems. We aimed to document the abundance and species richness of lianas and investigate their relationships with abiotic and biotic factors, based on data from a fully mapped 15 ha plot in a karst seasonal rainforest of Nonggang (SW China). Structural equation models (SEMs) were employed to estimate the path coefficients and variation of dependent variables, enabling a comprehensive analysis of the factors affecting the abundance and species richness of liana. Within the 15 ha plot, a total of 23,819 lianas were identified, encompassing 113 species from 34 families. These lianas constituted 24.16% of the total woody plant density and 33.44% of the species present, but only 4.32% of the total woody plant basal area. Lianas are primarily influenced by abiotic factors, especially elevation and phosphorus (P), with less impact from biotic factors. Our findings reveal that lianas, despite constituting a relatively small percentage of the total woody plant basal area, significantly contribute to the density and diversity of the forest. Notably, abiotic factors such as elevation and phosphorus availability predominantly shape the distribution and richness of lianas, highlighting the importance of these environmental variables. The findings offer valuable insights for future liana studies and the preservation of karst forests’ biodiversity.

喀斯特季节性雨林中藤本植物的丰度和物种丰富度：非生物因素和生物因素的影响

藤本植物是喀斯特季节性雨林的重要组成部分，但对它们的研究主要集中在非喀斯特地区。因此，在喀斯特生态系统中，对藤本植物的丰度和物种丰富度的研究仍然相对不足。我们的目的是记录藤本植物的丰度和物种丰富度，并研究它们与非生物因素和生物因素的关系，这些数据来自中国西南部弄岗喀斯特季雨林中一块 15 公顷的完整测绘地块。采用结构方程模型（SEM）估算因变量的路径系数和变异，从而对影响藤本植物丰度和物种丰富度的因素进行了全面分析。在 15 公顷的地块内，共发现 23 819 株藤本植物，包括 34 科 113 种。这些藤本植物占木本植物总密度的 24.16%，占物种总数的 33.44%，但只占木本植物总基部面积的 4.32%。藤本植物主要受非生物因素（尤其是海拔高度和磷）的影响，生物因素的影响较小。我们的研究结果表明，尽管藤本植物在木本植物总基部面积中所占比例相对较小，但对森林的密度和多样性却有显著贡献。值得注意的是，海拔高度和磷的可利用性等非生物因素主要决定了藤本植物的分布和丰富程度，凸显了这些环境变量的重要性。研究结果为今后的藤本植物研究和保护喀斯特森林的生物多样性提供了宝贵的启示。
