摘  要：
选用宁夏六盘山区5个代表测站自建站以来至2010年的各月暴雪资料,利用回归分析、谱分析、非参数检验等方法进行了统计分析,揭示六盘山区暴雨的时空变化规律。结果表明,六盘山区暴雪站次数在山顶最多,东麓次之,西北侧最少;年暴雪总站次呈线性减少趋势;4和10月是暴雪多发的月份;由雨夹雪转雪造成暴雪的站次数最多;年暴雪站次时间序列变化较为剧烈,发生了多次突变。百年一遇的日暴雪极值推算出现在北侧的固原站。

摘  要：
Based on the monthly data of blizzard measured by 5 representative meteorological stations in mountain area from the establishment of those 5 representative stations to 2010,this paper analyzed the spatial and temporal variation rule of blizzard in LiuPan Mountains according to the statistical analysis of regression analysis,spectral analysis and non-parametric tests.The results indicated that blizzard of LiuPan Mountains occurred mostly in the summit of mountain,followed by east foothill,moreover,the least was northwest sides;annual blizzard times showed linear decreasing trend;the times of blizzard in April and October was more;and the proportion of sleet changing snow which derived blizzard was most;change of time series of annual blizzard station was serious,and most mutation occurred.The maximum of blizzard in one day in 100 years return period was in north of Guyuan Station.
