Permafrost Map of Canada, Version 1

This map depicts the distribution, characteristics, and boundaries of permafrost and ground ice in Canada. Permafrost classification is based on the proportion of land that is underlain by permafrost within a a given area.Canada was divided into physiographic units, and each unit was classified in terms of permafrost extent and ground ice content. The map shows mountain permafrost as sporadic or isolated discontinuous permafrost, rather than as a separate category.

This map can be found in the The National Atlas of Canada, 5th Edition (1978-95) published by Natural Resources Canada.

本地图呈现了加拿大永久冻土（permafrost）与地下冰（ground ice）的分布、特征及边界。永久冻土分类以给定区域内受永久冻土覆盖的土地占比为基准。加拿大被划分为若干地貌单元，各单元均依据永久冻土覆盖范围与地下冰含量开展分类。本地图将山地永久冻土归类为零星或孤立的不连续永久冻土，而非独立类别。
