The precipitation form (snowfall,rainfall or fleet) have greatly influenced a large number of ecological processes,such as surface runoff,energy flow,and material circulation processes. Obviously,precipitation form is very sensitive to temperature changes. To discuss the effects of climate change on precipitation form,a dataset including average daily rainfall and temperature data of 27 stations from 1960 to 2015 in Heilongjiang province was employed to analyze the long-term change in annual snowfall and snowfall/rainfall ratio. The results indicate that: The annual mean snowfall in Heilongjiang province experienced a sharp growth with 34. 3% increase after a break which occurred around the year 2003. The long-term increase rate was 3. 3 mm per decade. On the contrary,no significant change was observed in annual mean rainfall in Heilongjiang province. Trend tests showed a 7. 6% per decade significant increase in snowfall/rainfall ratio in Heilongjiang. The main characteristic of change in snowfall spatial distribution was consistent upward trend except Huma station,but the amplitude of eastern parts was larger than the western ones. Otherwise,rainfall variation spatial pattern was differed among regions. In general the changes in the southern part were more strongly than the northern. The variation of fleet presented a distinct trend of decreasing from east to west. There was a large difference in fleet between the two sides of The Changbai-Hinggan mountains,presented as a sharp decline from the eastern part of the mountain to the western. The difference in spatial distribution between snowfall/rainfall ratio and snowfall was mainly reflected in the areas where rainfall was significant decreased,such as the western foot of Changbai mountains,where the rain shadow effect was extremely strong. The common impacts of delayed origin date and advanced end date resulted in the snowfall season range evidently shortened about 18 days in the last 56 years. The reason may be attributed to a significant temperature rise in Heilongjiang province. The spring warming should be considered as a major role rather than autumn because of the higher temperature variation,especially the increase in minimum temperature. There was no significantly change observed in average annual snowfall days. The amplitude changed in snowfall frequency in the northern was larger than the southern. Consistent with the snowfall growth,an increased trend of snowfall intensity was found in Heilongjiang,with a changing rate of 0. 8 mm per decade. In the context of global warming,higher snowfall rate phenomenon was observed in Heilongjiang province.
