兰州冰川冻土所研究工作的若干进展

Some Advance in the Research WorK of the Lanzhou Institute of Glaciology and Cryopedology

全球气候变暖还带来了一系列的生态灾难，例如海平面上升、冰川冻土融化、洪水、旱灾、台风、雨雪冰冻、地震等。

Global warming had brought a series of ecological disaster , such as sea-level rising , glaciers and permafrost thawing , flood , drought , typhoon , snow-rain freezing and earthquake .

但目前我国最有权威的兰州冰川冻土研究所，主要研究的是天然土体的垂直冻胀特性，与人工冻结法工程的冻胀模型不同。

However , Chinese most authoritative institute , Lanzhou Glacier Permafrost Institute , mainly studies the vertical frost heave properties of natural soil , which is different from frost heave models of artificial freezing engineering .

冰川、冻土地貌与堆积物

The Glacier , the Frozen Soil Landform with Accumulation

冰川、冻土、海冰有可能不断退缩，北极地区影响尤为严重。

The continuing retreat of glaciers , permafrost and sea ice is expected , with the Arctic region being particularly affected .

全球气候变暖会导致海平面升高、冰川、冻土融化以及湖泊水位下降等严重的危害。

Global warming will cause rising sea levels , glaciers , permafrost melting and lakes water level dropped , and so on .

现代冰川和冻土退缩对铁路影响的研究述评社会退缩青少年的友谊特点

A Review of the Effect of Degradation of Glaciers and Permafrost on Railways The Research of the Friendships of Adolescents with Social Withdrawal Behavior

利用冰川、冻土、积雪的时空变化，结合对高原特殊大气边界层的观测，研究青藏高原冰冻圈变化与能量水分循环过程；

By analyzing the space-time variations of glaciers , permafrost and snow accumulations together with observation of boundary layers , we study the variations of cryosphere and cycling processes of energy and water .

上世纪八十年代以来，长江源区出现了冰川退缩、冻土退化、湖泊萎缩、植被退化等现象。

Since 1980s , glacier retreating , permafrost degradation , lakes shrinking , vegetation degradation and so on happen in the regions .
