Utilizing MOD10A1 through July to September from 2002 to 2013, the temperature and precipitation of 21 meteorological observatories and HJ-1/CCD data, this paper took south and north slopes of Tianshan Mountain as the study field to analyze the distributional characteristics and influencing factors of the snowline. The results showed that the snowline distributional characteristics of south and north slopes of Tianshan Mountain presented that the north area was lower than the south area, the west area was lower than the east area, the snowline of south slope was sparser and had a small spatial gradient change; and the middle of north slope snowline was intensive and had a bigger spatial gradient change. The analysis on the whole study area showed that the correlation coefficient between snowline altitude and temperature was 0.159, partial correlation coefficient was -0.212; the correlation coefficient for precipitation was -0.668, partial correlation coefficient was -0.676. The precipitation is the main controlling factor on the distribution of snowline of south and north slopes of Tianshan Mountain. The study area could be divided into four different fields by analyzing different parts,, the snowline distribution of the middle and west part of north slope of Tianshan Mountain as well as the west part was mainly controlled by precipitation while snowline distribution of the east part of south slope of Tianshan Mountain was primarily affected by temperature.
