The duration of snow cover in the Tianshan Mountains，which is the length of time from the maximum snow cover to the minimum snow cover，i.e.，the residence time of snow on the ground throughout the year，shortened.Snow cover acts as a buffer in the hydrological system and can mitigate the effects of climate change on hydrology.If the snow cover duration is long，then snow exerts a greater effect on the regulation of the hydrological system，while the opposite is also true.The results show that snow cover duration decreased by eight days，from 216 in 2002 to 208 in 2013（Table 2）.A shorter of snow cover duration weakens the buffering effect of snow on the hydrological system，increasing the variability of water resources in the Tianshan Mountains，which will have adverse effects on the utilisation of water resources in oasis regions.
