摘要/Abstract

摘要： 植物生态化学计量是许多过程模型的重要参数，为了解高海拔地区优势物种的生态化学计量特征及其与土壤养分的关系，本文测定祁连山高寒草地生态系统5种优势物种叶片和根系的生态化学计量，分析了其与根际土壤养分的关系。结果表明：随着生长季推移，优势物种叶片总有机碳(Total organic carbon，TOC)含量相对稳定，全氮(Total nitrogen，TN)含量下降，而C∶N和C∶P则增加；大部分物候期下，青藏大戟(Euphorbia altotibetica Paulsen)的TN和全磷(Total phosphorus，TP)含量高于其他优势物种，且C∶N和C∶P低于其他优势物种，而垂穗披碱草(Elymus nutans Griseb.)的TN含量低于其他优势物种，且N∶P和C∶P高于其他优势物种；祁连山地区植物生态化学计量受到土壤化学计量的影响，植物生长主要受到N元素的限制。研究结果为相关植被模型和陆面过程模型的参数化提供了重要的基础数据。

Abstract: Plant ecological stoichiometry is an important parameter in many process models. To understand the ecological stoichiometric characteristics of the dominant species at high altitude region and their relationship with soil nutrients,we determined the ecological stoichiometry of leaves and roots of five dominant species in alpine grassland ecosystems in the Qilian Mountains,and analyzed their relationship with soil nutrients. The results showed that:with the growing season process,the total organic carbon (TOC) content in leaves of the dominant species was relatively stable,while the total nitrogen (TN) content was decreased,while the C∶N and C∶P was increased. In most phenological periods,the contents of TN and total phosphorus (TP) of Euphorbia altotibetica Paulsen were higher than those of other dominant species,and the contents of C:N and C:P were lower than those of other dominant species,while the TN content of Elymus nutans Griseb was lower than that of other dominant species,and N:P and C:P were higher than those of other dominant species. The ecological stoichiometry of plants in the Qilian Mountains is affected by soil stoichiometry,and plant growth is mainly limited by N. Our results provide important data the parameterization of many vegetation models and land-surface process models.
