The low growth form can also permit the plants to take advantage of the insulation provided by a winter snow cover.低矮生长形态也能让植物利用冬季积雪提供的隔离环境。
This is because middle- and upper- latitude timberlines are strongly influenced by the duration and depth of the snow cover.这是因为中纬度和高纬度地区的林木线受到积雪存留时间和厚度的强烈影响。
