- Abstract
Based on the MODIS remote sensing data meteorological data, and precipitation data of the Ebinur Lake Basin from 2001 to 2017, the temporal and spatial distribution characteristics, changing trends and driving factors of snow cover in the Ebinur Lake Basin from 2001 to 2017 were analyzed. The results are as follows. (1) Variations in snow cover in Ebinur Lake Basin showed an increasing trend from 2001 to 2017. (2) A negative linear correlation existed between snow cover and surface temperature, whereas a positive linear correlation existed between snow cover and precipitation in Ebinur Lake Basin during 2001 and 2017. (3) When the surface temperature was stable, the partial correlation coefficients between snow and precipitation were within –0.83-0.90, accounting for 67.05% of the positive correlation area. When precipitation was stable, the partial correlation coefficients between snow cover and surface temperature were within –0.97-0.79, accounting for 95.67% of the negative correlation area. (4) The area of snow cover change affected by climate factors in the Ebinur Lake Basin accounted for 55.32% of the total area, which was mainly distributed in the southeastern and northwestern areas in the Ebinur Lake Basin. Among them, the area as precipitation was the main driving factor accounting for 31.80%, while the area as surface temperature was the main driving factor accounting for 1.19%, the areas as surface temperature and precipitation were the strong driving factors accounting for 0.49%, and the areas as surface temperature and precipitation were the week driving factors accounting for 21.84% of the total area.
