| 摘 要： | 采用新疆54个气象站近50年的气象资料，分析新疆沙尘暴时空分布特征、年际和年内演变趋势及年际演变的影响因素。结果显示：新疆沙尘暴近50年以来空间分布特征是南疆多于北疆，沙尘暴主要出现在3～10月，其中4～7月为高发时段。年际演变趋势20世纪80年代以来较60、70年代都有所减少；80年代以后沙尘暴发生日数减少。

| Abstract: | Sandstorm of Xinjiang was analyzed by using the weather data of 54 meteorological stations of Xinjiang in recent 50 years, including spatial and temporal distribution characteristics, Annual and seasonal variation tendency, and factors affecting the inter annual variation. According to the spatial distribution characteristics of sandstorm in Xinjiang in recent 50 years, there were more sandstorms in the south than in the north of Xinjiang. Sandstorm mainly occurred during March and October, and the peak time was from April to July. Since 1980s, the sandstorms were decreased compared with 1960s and 1970s.The number of Sandstorm decreased after 1980s. |
