The characteristics of snow cover,the number of snow cover days and the snow cover depth in the Taibai Mountains were analyzed by using the snow cover land observation data in Taibai Weather Station from 1962 to 2014 and the observation records of alpine snow cover in Taibai and Meixian Weather Stations from 1980 to 2014,as well as satellite remote sensing data from 1988 to 2010. The results showed that in the western middle mountain zone of the Taibai Mountains the snow cover beginning day had delayed,the snow cover ending day had advanced,the duration from snow cover beginning date to snow cover ending date had reduced,the annual days and depth and area of snow cover had presented a decrease tendency from 1962 through 2014. The same variation had also taken place in the western middle and high mountain zones of the Taibai Mountains from 1980 through 2014,with annual snow cover day decreasing rate of 3.2 d·(10a) ~(- 1) and 8.9 d·(10a) ~(- 1), respectively,in the middle and middle and high zones. The change of snow cover beginning and ending dates and the snow cover days had varied not so obviously from 1980 through 2014. Analyzing the satellite remote sensing monitoring data showed that the snow cover area has decreased in the undulation in the Taibai Mountains. Correlation analysis revealed that there was a close relation between temperature and cumulative snow depth in the western middle mountain zone of the Taibai Mountains from 1962 through 2014. It is clear that the temperature rise is the main reason of precipitation decreasing and the accumulative snow depth decreasing. There were few snow cover days in July in the middle and high mountain zones during 1980 - 2014,and one of eight sights in Guanzhong,saying " the snow accumulation in lunar June (July in the Gregorian calendar) on the Taibai Mountains" in history,couldn't be presented in the mountains.
