中文摘要	融雪径流是寒旱区草原流域径流的重要补给方式和水源。融雪径流时间随着气象条件的变化而改变,这严重影响着研究区年径流量和各季径流量的分配。采用锡林河水文站19602009年水文年流量质心时间CT来表示锡林河水库上游融雪径流开始时间,分析了融雪径流时间变化特征。结果表明:锡林河水文站融雪径流时间具有提前趋势,且融雪径流发生在3月末与4月初期,锡林浩特气象站融雪期(34月)气温升高或积雪期(上年10月当年4月降水量增加,锡林浩特水文站融雪径流时间会提前,但融雪期气温对融雪径流时间作用更明显。由融雪径流时间与年径流量和四季径流量的相关关系,可得融雪径流时间提前,年径流量、冬、夏、秋季径流量均会减小,而春季径流量会增大,但融雪径流时间与年径流量、夏、秋季径流量关系最为密切,相关系数分别为0.456,0.600与0.676。这对寒旱区草原流域合理利用雪水资源和洪水预警有重要作用。
英文摘要	Snowmelt runoff is an important supply and source of water of cold and arid regions.The snow melting runoff time will change with the variation of the meteorological conditions,which seriously affect the distribution of annual and seasonal runoffs of the study area.The Timing of the Center(CT)of Mass of Flow of Xilin River Hydrological Station 19602009 hydrological year was used to represent the snowmelt runoff start in the upstream of Xilin River Reservoir and analyze the time characteristics of snowmelt runoff. The results showed that the time of snowmelt runoff has earlier trend for Xilin River Hydrological Station, and snowmelt runoff occurred in late March and early April,at the Xilinhot Weather Station,temperature during the snow melting period (March to April)or precipitation during the snow period (last year in October to the April of this year)increased,the time of snowmelt runoff will be ahead,but the effect of the temperature on the time of the snow melting was more obvious.By Pearson correlation coefficients between CT and annual and seasonal runoffs,if the time of snowmelt runoff is in advance,the annual runoff,winter, summer,and autumn runoff will decrease,and spring runoff will increase,but Pearson correlation coefficients between CT and annual runoff,summer and autumn runoff is most closely,correlation coefficient is 0.456,0.600,0.676,respectively,which provided an important support in rational use of snow water resources and flood warning in the cold and arid regions prairie watershed.
