喀斯特丘陵是由石灰岩和其他可溶岩石溶解形成的锯齿状地形，广泛分布于包括中国南方在内的热带森林地区。它们的特点是水和养分供应的急剧马赛克，从土壤发育不良的裸露山顶到偶尔发生洪水的山谷，树木显示出物种特异性分布。在这里，我们报告的关系，叶功能性状的热带喀斯特树木的生境偏好。我们描述了中国广西省季节性喀斯特雨林中19种热带树种的叶特征，12种原位和13种迁地在非喀斯特植物园中，作为一个共同的花园，其中6种样品在两个。我们研究了所测量的叶性状如何与物种的栖息地亲和力有关，并评估了自然栖息地与植物园之间的性状一致性。单位面积叶质量（LMA）和光学性状（400和1,050 nm之间的光吸收和反射特性）显示出显着的相互关联和栖息地，山顶物种显示出高值的LMA和低值的光化学反射指数（PRI）。对于在喀斯特森林和植物园中采样的6个物种，LMA，叶干物质含量，气孔密度和每面积的脉长表现出不一致的种内变异，而一些性状（气孔指数和叶片厚度）在两个站点之间是相似的。总之，树木专门在暴露的喀斯特山顶，土壤少的特点是厚叶，高组织密度的保守资源的使用指示，这种性状综合征可能会被感测到与PRI远程。
Karst hills, that is, jagged topography created by dissolution of limestone and other soluble rocks, are distributed extensively in tropical forest regions, including southern parts of China. They are characterized by a sharp mosaic of water and nutrient availability, from exposed hilltops with poor soil development to valleys with occasional flooding, to which trees show species‐specific distributions. Here we report the relationship of leaf functional traits to habitat preference of tropical karst trees. We described leaf traits of 19 tropical tree species in a seasonal karst rainforest in Guangxi Province, China, 12 species in situ and 13 ex situ in a non‐karst arboretum, which served as a common garden, with six species sampled in both. We examined how the measured leaf traits differed in relation to species’ habitat affinity and evaluated trait consistency between natural habitats vs. the arboretum. Leaf mass per area (LMA) and optical traits (light absorption and reflectance characteristics between 400 and 1,050 nm) showed significant associations with each other and habitats, with hilltop species showing high values of LMA and low values of photochemical reflectance index (PRI). For the six species sampled in both the karst forest and the arboretum, LMA, leaf dry matter content, stomatal density, and vein length per area showed inconsistent within‐species variations, whereas some traits (stomatal pore index and lamina thickness) were similar between the two sites. In conclusion, trees specialized in exposed karst hilltops with little soils are characterized by thick leaves with high tissue density indicative of conservative resources use, and this trait syndrome could potentially be sensed remotely with PRI.
