In this paper, MODIS snow cover remote sensing data and Geographic Information System (GIS) technology were used to analyze extraction methods of the snow cover area information. And taking a river drainage basin as an example, this paper studied the variation characteristics of snow cover area in mountainous watershed from 2005 to 2007 in spring and summer to further provide a basis and reference for understanding the process of snowmelt in this drainage basin. The results show that the snow cover area of the river drainage basin has gradually decreased from March, and the smallest snow cover area in the drainage basin appeared in July. The snow cover area has gradually increased since August, and the annual snow melting period is from April to July.
