摘要/Abstract

摘要： 地形对植物生存策略的权衡具有重要影响.研究叶片生态化学计量特征沿海拔梯度的分异规律,有助于加深理解植物对环境变化的响应及其生态适应性.对青藏高原东北缘不同海拔(4400～4700、4701～5000和5001～5300 m)火绒草叶片C、N、P含量及其化学计量比进行研究.结果表明: 3个海拔火绒草叶片C、N、P含量分别为405.36、18.42和0.94 g·kg^-1;C/N、C/P、N/P分别为22.67、467.61和20.3;火绒草叶片N、P含量表现出趋同的变化规律,随海拔升高而增加;火绒草叶片C、N、P含量及C/N、C/P、N/P的变异系数均≤30%,其大小依次为P(30%)>C/P(29%)>C/N(18%)>N(17%)>N/P(15%)>C(3%);火绒草植物生长主要受P的限制.

Abstract: Topography has major impacts on the trade-off of plant survival strategies. Exploring the differential pattern of leaf ecological stoichiometry along the elevation gradient contributes to a better understanding of plant’s response to environmental changes and its ecological adaptability. We investigated leaf C, N, and P concentrations and stoichiometric ratios of Leontopodium leontopodioides at three elevations, including from 4400 m to 4700 m, from 4701 m to 5000 m, and from 5001 m to 5300 m, on the northeastern margin of the Qinghai-Tibetan Plateau in China. The results showed that the concentrations of leaf C, N, and P of L. leontopodioides were 405.36 g·kg^-1, 18.42 g·kg^-1 and 0.94 g·kg^-1, respectively. Leaf C/N, C/P, and N/P were 22.67, 467.61 and 20.30, respectively. The concentrations of leaf N and P of L. leontopodioides consistently increased with the increases of elevation. The coefficient of variations for leaf C, N and P concentrations and ratios of L. leontopodioides were all less than 30%, with an order of P (30%) > C/P (29%) > C/N (18%) > N (17%) > N/P (15%) > C (3%). The growth of L. leontopodioides on the Qinghai-Tibetan Plateau was mainly limited by P availability.
