摘　　要：大兴安岭北部是我国多年冻土最为发育的地区之一,多年冻土的存在和分布受植被、积雪等局地因素的影响十分显著,形成了独特的兴安-贝加尔型多年冻土.随着该区社会经济的发展,多年冻土对寒区环境以及工程生产活动的影响越来越大.近几年来逐步在大兴安岭北部建立了以多年冻土为主要研究对象的监测网络,包括多年冻土地温监测网络、自动气象站、雪特性观测系统、活动层温度-水分观测系统以及地面融沉监测断面,获得了一系列有意义的数据和成果.做好大兴安岭北部多年冻土及其周围植被、气候及冻土灾害的监测具有重要的基础性和前瞻性科学价值.Permafrost is well developed in the Northern Da Hinggan Mountains,Northeast China.However,its development and distribution are significantly affected by local factors such as vegetation,snow cover and so on.It is also known as Xing'an-Baikal type permafrost consequently.In recent years,permafrost monitoring systems have been gradually established in the northern Da Hinggan Mountains,including ground temperature monitoring system,automatic meteorological stations,snow properties observation system,temperatures and moisture of active layer observation system and thaw settlement monitoring system.Up to now,a series of data have been collected for analysis,and meaningful results have been obtained too.
