Additional field(s): Environment & Ecology, Meteorology
English term or phrase: permafrost
Definition from weatherdudes.com:
A layer of soil at varying depths below the surface in which the temperature has remained below freezing continuously from a few to several thousands of years.

Example sentence(s):
  • ecent warming has degraded large sections of permafrost, with pockets of soil collapsing as the ice within it melts. The results include buckled highways, destabilized houses, and "drunken forests" of trees that lean at wild angles. National Center for Atmospheric Research
  • The different climatic conditions determinate the cryogenic asymmetry of the Antarctic Peninsula with respect the continuous permafrost on north-east side and the discontinuous permafrost on the west sector. tierradelfuego.gov.ar
  • Understanding permafrost is not only important to civil engineering and architecture, it is also a crucial part of studying global change and protecting the environment in cold regions. The National Snow and Ice Data Center

永久冻土
Definition:
一个地质学的名词,指当冻土层(Tundra)处于水的结冰点以下(即0℃)超过两年的状况。永久冻土地带的泥土不一定有水份,例如在无孔基岩(不透水的岩石)里就不可能有水;但在大多数情况下,水不单存在,而且更超过地表物料的潜在水饱和量。一般的冻土层在气候回暖或受到强压时,冻土内的冰会溶解成为水;但永久冻土的所在之处,即使在天气回暖之时,气温仍然在冻点以下,使冻土内的冰不能再次溶解成为水份,因而使冻土的组成不变。

Example sentence(s):
  • 专家认为,受全球气候变暖影响,到本世纪末北半球的永久冻土层面积将减少一半,而冻土层季节性融化深度也将增加一倍,使得建设在永久冻土层之上的城市及其他设施面临严重的地质威胁。 - 中国干旱气象网  
  • 多年冻土(permafrost),又称永久冻土,指的是持续三年或三年以上的冻结不融的土层。其表层冬冻夏融,称季节融化层。多年冻土层顶面距地表的深度,称冻土上限,是多年冻土地区道路设计的重要数据。多年冻土分为两层:上部是夏融冬冻的活动层;下部是终年不融的多年冻结层。多年冻土是寒冷气候(年均气温<—2℃)区的产物。 - 百度知道  
  • 合正在修建的青藏高原风火山隧道的安全、优质施工技术,对高原永久冻土区隧道在严寒缺氧条件下的开挖、支护、衬砌、防排水、通风和机械化配套等施工新技术进行了总结,可为类似条件下的冻土隧道修建提供技术指导. - ilib  

Explanation:
也可称作永冻土或多年冻土
