摘 要：Different remote sensing sensors were employed to obtain the characteristics of icing（aufeis） in the Brooks Range,Alaska and the Kunlun Mountains,*** truth results support remote sensing observations and led to the development of techniques to determine ice formation and spring water *** creates an important water storage,and an engineering hazard in the permafrost *** Synthetic Aperture Radar（SAR） is a powerful and sensitive sensor for ice detection,estimating volume of the ice,and freeze/thaw *** 27-30% of winter baseflow contributes to the icing at the Kuparuk Aufeis *** imagery from the Brooks Range indicates many of the high discharge springs are located less than 500 m *** limestone areas with glacial *** springs have survived at least through the last ***,the size of these icing deposits was similar to those found recently by identifying ASTER（Advanced Spaceborne Thermal Emission and Reflection Radiometer） shortwave infrared（SWIR） data.
