ABSTRACT: Scientific and comprehensive monitoring of snow cover changes in the
Pamirs is of great significance to the prevention of snow disasters around the
Pamirs and the full utilization of water resources. Utilize the 2010-2020 snow
cover product MOD10A2, Synthesis by maximum, The temporal and spatial variation characteristics
of snow cover area in the Pamirs in the past 11 years have been obtained.
Research indicates: In terms of interannual changes, the snow cover area of the
Pamir Plateau from 2010 to 2020 generally showed a slight decrease trend. The
average snow cover area in 2012 was the largest, reaching 54.167% of the total
area. In 2014, the average snow cover area was the smallest, accounting for
only 44.863% of the total area. In terms of annual changes, there are obvious
changes with the change of seasons. The largest snow area is in March, and the
smallest snow area is in August. In the past 11 years, the average snow cover
area in spring and summer showed a slow decreasing trend, and there was almost no
change in autumn and winter. In terms of space, the snow cover area of the
Pamirs is significantly affected by altitude, and the high snow cover areas are
mainly distributed in the Karakoram Mountains and other areas with an altitude
greater than 5000 meters.
