摘　　要：俄罗斯永冻区冻结层上水动态特征的研究对了解寒区冻结层上水具有重大的意义。文章通过对俄罗斯永冻区冻结层上水动态特征的研究,指出:(1)俄罗斯典型地区的冻结层上水动态特征为:其动态与气温变化密切相关,且含水层具有冻结层上水和冻结层间水的特点;(2)融层地下水包括包气带不透水融区地下水、热融区地下水、上层滞水;(3)融层地下水动态特征为:融区水具有冻结层间水的特点,在一年内相当长时期内具有渗透压力状态,包气带中垂向水分交换过程在季节性融化层的水文情势中拥有不同的作用;(4)寒区地下水和地下冰之间的转换过程影响着冻结层上水水体的形成及其水文状况。The research of movement characteristics of frozen groundwater of permafrost region of Russia is important to study the frozen groundwater of cold region.Through the Russian permafrost regions to study the dynamic characteristics offrozen groundwater.It points out：（1）Russia typical areas of frozen groundwaterdynamic characteristics as follows：the dynamic is closely related to the temperature change and aquifer has the characteristics of the frozen groundwaterand frozen between water;（2）Melt layer groundwater including vadose impervious area groundwater,hot melt area groundwater,perched water;（3）The melting layer groundwater dynamic characteristics as follows：the melting zone freezing water has the characteristics of interlayer water,quite a long period of time in a year with osmotic pressure state,vertical moisture in the vadose zone exchange process in seasonal melt layer has a different role in hydrological regimes;（4）Cold and the conversion process between groundwater and underground ice affects the formation and hydrological conditions of frozen groundwater.
