| 摘 要： | 黑龙江省有近15×104km2多年冻土,可分为大兴安岭北部大片多年冻土亚区、大兴安岭中部大片岛状多年冻土亚区、大小兴安岭稀疏岛状多年冻土亚区等,冻土层厚度在5～100m。岩性、地形、纬度、高度对冻土分布产生影响。气候变暖和人为活动将使冻土退化。

| Abstract: | There are nearly 150,000square Kilo meters permafrost all around Heilon gjiang Province,they can be divided into three parts,large -scale permafrost subregion in the north of Daxing' an Mountain,large -scale island permafrost subregion in the middle of Daxing' an Mountain,sparse island permafro st subregion in Daxing' an Mountain,the depth of frozen grou nd is between5and 100meters.The distributing of frozen ground is effected by litholo gy,landform,latitude and alritude.Frozen ground will degenerate under the influence of climate warming up and artificial acti vity. |
