英文摘要	Snowfall in mountainous areas provides indispensable water sources for arid and semi-arid watersheds. changes in snowfall and snowmelt regimes have significantly impacted the water resources' variations and management. this study addresses the ratio of snowfall to precipitation (s/p) in the tian shan mountains, china. it aims to examine changes in s/p ratio and its synchronization with climate change. the results show that the average s/p ratio experienced a downward trend under the precipitation and snowfall increases as well as temperature increases during the cold seasons in 1961-2010. spatially, the s/p ratios show an increasing trend in the boertala valley and the southern slope of the middle tian shan mountains, but a decreasing trend in yili valley, and the western and the northern slope of the middle tian shan mountains. the s/p ratios decreased significantly in middle altitudes with elevation ranging from 1500 to 2500 m, but either decreased or increased at elevations below 1500 m due to a temperature inversion in the elevation belt. in high altitudes with elevation over 3500 m, the magnitudes of the decreased s/p ratios were small because the temperature was always below freezing. the decreases in s/p ratio was mainly attributed to the relative changes in snowfall (ds/s) being less than that in precipitation (dp/p), whereas the increases in s/p ratio resulted from the relative changes in snowfall (ds/s) being more than that in precipitation (dp/p). temperature increases have also lead to the decreases in s/p ratios to some extent.
