【摘要】 受高原环境中多变的气候、多样的地形和独特的生物交流屏障或迁移通道等因素的综合影响,青藏高原孕育了全球最丰富的冰缘植物多样性资源,同时具备显著的时空环境气候梯度,以及多样的小生境类型,是研究自然生态系统中极端环境内物种成种和生物多样性形成与适应机制的"天然实验室"。本文结合植物区系学、系统学、谱系地理学、植物生态学等学科的研究资料和最新研究进展,分析青藏高原冰缘生态系统内植物多样性特征及其起源、演化和适应机制,并对全球气候变化对青藏高原冰缘植物的影响及其响应方式和变化趋势进行预测,以期为青藏高原冰缘带植物多样性保护提供有力的理论依据。更多还原

【Abstract】 Due to its highly variable climates, diverse topographies, and unique corridor or isolation barrier for plant species, the Qinghai-Tibet Plateau(QTP) hosts the richest alpine subnival plant biodiversity globally. The abundant alpine subnival plant diversity in combined with the most pronounced temporal and spatial gradient and extremely diverse microhabitats types in QTP offer a ‘natural laboratory’ for studying the speciation and diversity formation in hostile environments in the natural ecosystem And ithas attracted many researchers’ interests. In this paper, combined with some recent progresses and information from study areas including plant floristics, plant systematics, plant biogeography, plant ecology etc. we comprehensively analysize the characteristics of plant diversity in alpine subnival ecosystem in QTP as well as its origins, evolution, adaptation and predict its possible response and changes under the background of global climate changes.更多还原
