在高纬度地区或高海拔地区,年平均温度在0℃以下,大气降水多为固体状态,形成一定厚度的积雪,经过压实、融冻成为冰川冰。以冰川冰形式储存的固体水资源称为冰川水资源。
同时,全球变暖导致的喜玛拉雅冰川消融并不能帮助补充本地区短缺的水资源。
It is also clear that global warming's accelerated melting of the nearby Himalayan glaciers is not the primary culprit in the region's water deficit.
尽管地球上水资源丰富,但是超过97%的水为咸水,而在剩下的不到3%的水又有一半以上要么是冻结在两极,要么是构成了冰川。
THERE is a lot of water on Earth, but more than 97% of it is salty and over half of the remainder is frozen at the poles or in glaciers.
人们只能够利用那余下的3%,这些水来自河流、湖泊、地表,我们无法利用所有的水资源,因为有些是冰川和冰山。
Man can only use the other 3%fresh water that country rivers, lakes and from otherground and we can't ever use all of that becausesome of them are the iceberges and glaciers.
