| 摘 要： | 选取新疆北疆20个站1961-2006年积雪及稳定积雪日数、最大积雪深度资料,同时选择冬季降水量和气温稳定通过0℃以下的日数作为积雪的影响因子，分析了46 a来北疆积雪的变化趋势。结果表明：46 a来最大积雪深度呈显著增加趋势，平均年增长0.8%，其变化与冬季降水量增加有关，呈正相关；积雪日数和稳定积雪日数也呈稍增加趋势，增加主要发生在1960-1980年代，1990年代以来有所减少，其变化与气温稳定通过0℃以下的日数呈显著正相关。

| Abstract: | Based on the meteorological observations at 20 representative stations in Northern Xinjiang in 1961-2006,trends of snow cover(including the maximum depth,days of snow cover and steady snow cover) were investigated using the methods of autoregressive moving average model,second order principal value function,and correlation analysis.The results show that the maximum depth of snow cover was significantly positively correlated with winter precipitation;the maximum depth increased at an average annual growth ra... |
