摘要
通过对寒区冻结层上水的类型与动态的研究,不仅能进一步了解寒区冻结层上水,也对地下水的研究具有深远的影响。通过对俄罗斯地区及欧亚大陆山区观测资料的研究,以水相位转换的论述方法,指出:(1)地下水动态的定义是地下水水体动态为地下水水位、水量和运动速度的时间性变化;(2)依据在寒区具有含水层和水位的冻结层的特点,将低温流体动力地下水划分为3个类型:填积型、衰减型和准稳型;(3)低温流体动力水的3个类型是冻结层上水、冻结层间水、冻结层下水固有的;(4)冻结层上水的特点是它的类型和子类既具有多年性,又具有季节性。
The research of cold and frozen layer water types and dynamic not only can learn more about freezing cold water layer,but also can have a profound effect on the study of groundwater.This paper analyzes the Russia and Eurasia mountain observation on the basis of taking the discourse of the water phase transformation method.It points out：（1）The definition of groundwater dynamic：groundwater dynamic is timeliness change of groundwater water level,water quantity and speed.Actually,it does not depend on groundwater buried depth,rock formations and water-bearing rocks belt composition;（2）According to the cold regions has the characteristics of the aquifer and the water level of frozen layer,cryogenic fluid power of groundwater is classified into three types：fill,attenuation and quasi stationary type;（3）Water above frozen layer,water between frozen layer and water below frozen layer all have three types of the low temperature fluid power water.Type and subclass of water above frozen layer are seasonal and annual properties.
