摘要/Abstract

摘要： 植物多样性-生物量关系的研究主要关注地上生物量和地上植物特征,但占比更大且理应承载更多群落功能的地下部分却较少被研究,其机理也较少被探讨。本研究选用垂穗披碱草(Elymus nutans)、花苜蓿(Medicago ruthenica)、鹅绒委陵菜(Potentilla anserina)、黄帚橐吾(Ligularia virgaurea)、黄花棘豆(Oxytropis ochrocephala)构建了多样性梯度为1~5、重复4次且周期为1年的盆栽试验,探讨了地上与地下的多样性-生物量关系。结果表明:物种增加使净多样性效应显著增强(P <0.001),使群落获得更高的地下和总生物量。净多样性效应的次要来源特征依赖性互补效应随着物种丰富度的增加而显著增加(P <0.001),根冠比和平均根径的变化在其中发挥重要作用。非特征依赖性互补效应和优势度效应的作用却十分有限。因此,根冠比和平均根径带来的选择效应的变化是正向植物多样性-生态系统功能关系的关键驱动因素,应给予更多的关注。

Abstract: Studies on the relationship between plant diversity and biomass has primarily focused on above-ground biomass and above-ground plant traits. However,the less-studied below-ground component,which constitutes a much larger portion of the population and performes more community's functions,is also crucial. In this experiment,we conducted a pot plant experiment using five common plants:Elymus nutans,Medicago ruthenica,Potentilla anserina,Ligularia virgaurea,and Oxytropis ochrocephala. The experiment was designed to create a diversity gradient of 1 to 5,repeated 4 times and within la period. We investigated the relationship between plant diversity and above-ground and both below-ground biomass. The results showed that communities with increased species resulted in a significant net diversity effect (P<0.001),leading to the increase in below-ground and total biomass. The secondary source of the net diversity effect,known as the trait-dependent complementarity effect,was significantly enhanced by increasing species richness (P<0.001). Changes in the root-shoot ratio and root average diameter played a crucial role in this process. However,the trait-independent complementarity effects and dominance effectsplayed a very limited role. In conclusion,changes in selection effects due to root-shoot ratio and root average diameter are key drivers of the positive relationship between plant diversity and ecosystem function. This suggests that these factors warrant greater attention in the future studies.

Key words: Plant diversity, Community biomass, Net diversity effects
