Abstract
Leaf traits were affected by soil factors and displayed varietal differences in forest. However, few examples have been reported on the Island ecosystems. We comprehensively investigated 9 leaf traits (leaf length, leaf width, leaf area, SLA, leaf fresh weight, leaf C content, leaf N content, leaf K content, leaf C:N ratio) of 54 main subtropical woody species and soil parameters (soil pH, total C content, total N content, total K content, available N content, available P content, available K content and soil moisture) in Neilingding Island, Shenzhen, southern China. Intra-and interspecific variation of leaf traits were measured and their correlations with soil parameters were explored. The interspecific variations of leaf C:N ratio, leaf N content and leaf fresh weight were higher than their intraspecific variations. The intraspecific variation of leaf K content was larger than that of interspecific one, accounting for 80.69% of the total variance. Positive correlations were found among intraspecific coefficients of variations in leaf morphological traits. The correlation analysis between the variation of intraspecific traits and the variation of soil parameters showed that changes in soil factors affected leaf morphology and stoichiometry. The interaction between soil moisture and soil available P content was the key factor on intraspecific variations of leaf traits including leaf area, leaf fresh weight, leaf C and leaf K content. We concluded that leaf traits of plants in the island were tightly related to soil parameters. Soil parameters, especially soil moisture and available P content, affected plant leaf morphology and stoichiometry at the local scale.
叶片性状受土壤因素的影响,在森林中表现出品种差异。然而,很少有关于海岛生态系统的报道。我们对中国南方深圳内伶仃岛 54 个主要亚热带木本物种的 9 个叶片性状(叶长、叶宽、叶面积、SLA、叶鲜重、叶 C 含量、叶 N 含量、叶 K 含量、叶 C:N 比)和土壤参数(土壤 pH 值、总 C 含量、总 N 含量、总 K 含量、可利用 N 含量、可利用 P 含量、可利用 K 含量和土壤水分)进行了全面研究。测定了叶片性状的种内和种间差异,并探讨了它们与土壤参数的相关性。叶片C:N比、叶片N含量和叶片鲜重的种间差异高于种内差异。叶片 K 含量的种内变异大于种间变异,占总变异的 80.69%。叶片形态性状的种内变异系数呈正相关。种内性状变异与土壤参数变异之间的相关分析表明,土壤因子的变化会影响叶片形态和化学计量学。土壤水分和土壤可利用磷含量之间的相互作用是影响叶片面积、叶片鲜重、叶片 C 和叶片 K 含量等叶片性状种内差异的关键因素。我们的结论是,岛上植物的叶片性状与土壤参数密切相关。土壤参数,尤其是土壤水分和可利用磷含量,在当地范围内影响着植物叶片的形态和化学计量。
