摘要

以毛乌素沙地丘间低地30种主要植物为研究对象,比较不同功能群植物叶片性状的变异特征,分析植物叶片各性状之间的关系。结果表明:30种植物的比叶面积的变异系数最大,比叶面积与叶片干物质含量呈现极显著的负相关关系,叶片干物质含量与叶片碳含量呈显著的正相关关系,叶氮含量与叶片碳氮比呈极显著负相关关系,叶面积与其他所有的叶片性状都无相关性。比叶面积、叶片干物质含量、叶面积、叶氮含量和叶碳含量在不同功能群之间存在显著差异,叶片碳氮比在不同功能群之间没有显著差异。研究结果有助于了解毛乌素沙地丘间低地环境变化对植物种群的作用,增进对丘间低地植被演变特征的认识。

Abstract

In this study, patterns of leaf traits of 30 plants in inter-dune lowland in the Mu Us Sandy Land were investigated to detect their difference among functional groups and relationships among each trait. The results showed that the variation coefficient of specific leaf area(SLA) of 30 plants was the highest among the 7 leaf traits measured. Pearson correlation showed that SLA was negatively correlated with leaf dry matter content(LDMC). However, LDMC was positively correlated with leaf carbon concentration(LCC). Leaf nitrogen concentration(LNC) was negatively correlated with the ratio of carbon and nitrogen(LC/N). There was no significant correlation between leaf area and other leaf traits. One-way ANOVA analysis showed that SLA, LDMC, Leaf Area, LNC, and LCC were significantly different among the functional groups, however, no significant difference was found for LC/N. Our results would be helpful for understanding the role of environmental changes on the plant population in inter-dune lowland of Mu Us Sandy Land and enhancing the knowledge of vegetation evolution characteristics of inter-dune lowland.
