In this region, because there is abundant precipitation for glacier development, glaciers are sensitive to temperature changes. Consequently, glacial extent changes most dramatically during the alternation of glacial and interglacial periods, such as the last glacial period.
是我国海洋性冰川发育的主要地区之一，其在水分周转中周期短，强度大，变化幅度也较大，对气候波动的响应敏感，因此在冰期—间冰期旋回中雪线就会出现大范围的波动。

The geographic distribution of diploids and polyploids in G. pentaphyllum may be associated with the past ecological environments of different areas,especially during the glacial period.
绞股蓝的多倍化并没有显著扩大该种的分布范围,其二倍体与多倍体的地理分布差异可能反映了不同地区历史上的生态环境差异,特别是冰期时不同地区的生态环境。
