摘要
由于环境条件恶劣,所以高山地区(特别是树木分布线以上区域)和极地地区通常被认为是陆地上最为极端的生境之一,但是高山和极地区域却也拥有众多极具价值的生物资源。因此自1896年以来,作为生物进化研究中的热点和难点,高山和极地植物对生境的适应机制和策略一直倍受研究者们的关注。本文以植物生态学、植物生理学、气象学等学科资料,分析了高山和北极植物的特有生活型,并认为它是一种主要的适应机制。通过对全球主要高山和极地植物生长地的局部气候特点的分析,作者肯定了植物的特化适应现象与极端环境各因素间存在的密切关系。
The alpine regions (particular in the region above the tree line) and arctic regions are regarded as one of the most extreme areas of the land because of their harsh environmental conditions. However, both regions have very rich and valuable biological resources in the world. Therefore, the adaptive mechanism and strategies of the alpine and arctic plants have received much attention since 1896, because they are the hotspot and bottleneck in the study of the evolutionary courses of the creatures. In this paper, the special life form of alpine and arctic plants are analyzed with data from many study fields such as plant ecology, plant physiology, aerography and so on and regarded it as a major adaptive mechanism. Furthermore, the authors affirmed the closely relationship between the characteristic adaptive phenomena and the stressful environmental factors by analyzing the regional climatic features of the habitation in which the alpine and arctic plants grow.
