摘要: 首次探究在青藏高原极端环境下瑞香狼毒(Stellera chamaejasme)在数量生物量相关性上对环境的适应特性和生存策略,旨在填补植物数量生物量生长相关性研究空白,同时为青藏高原生物多样性保护提供理论依据和决策参考. 采用野外调查和统计分析相结合的方法,对瑞香狼毒植株高度、叶片数量、花朵数量进行生长相关性研究. 结果表明:植株高度对叶片数量和花朵数量均具有显著正向影响,并且影响程度均为中等水平;叶片数量对花朵数量也具有显著正向影响,并且影响程度也为中等水平;植株高度既可以与花朵数量之间直接相关,也可以通过叶片数量的中介效应进而与花朵数量之间间接相关. 瑞香狼毒的植株高度、叶片数量、花朵数量不仅呈现规律性分布,而且相互之间紧密相关,这就是瑞香狼毒对青藏高原极端环境的适应特性和生存策略. 基于此,提出一些青藏高原生物多样性保护的建议.

Abstract: The adaptation characteristics and survival strategies of plants to the environment on the correlation of quantitative biomass in the extreme environment of the Qinghai-Tibet Plateau is firstly explored to fill the gap in the study of the correlation of plant quantitative characteristics and growth. Meanwhile, the theoretical basis and decision-making reference for biodiversity conservation in Qinghai-Tibet Plateau is provided. The correlation among plant height, leaf number and flower number of Stellera chamaejasme was studied by means of field investigation and statistical analysis. The results showed that plant height had a significant positive effect on the leaf and flower number, and the degree of influence was moderate, and so did the leaf number on the flower number. Plant height is related to flower number through the intermediary effect of leaf number. The plant height, leaf number and flower number of Stellera chamaejasme are closely related as the adaptation feature and survival strategy of Stellera chamaejasme under extreme environment of the Qinghai-Tibet Plateau. Based on the above, some suggestions for biodiversity conservation in Qinghai- Tibet Plateau are made.

Key words: Qinghai-Tibet Plateau, Stellera chamaejasme, quantitative biomass, survival strategy
