| 摘 要： | 通过对1960-2005年新疆54个气象站的气象资料进行分析,研究了新疆不同强度等级沙尘暴天气的时空分布年际演变趋势.结果显示：新疆各强度等级沙尘暴天气的发生区域均在逐年缩小,强沙尘暴、扬沙发生区域有东移的趋势,浮尘空间分布格局显现出向南退缩的趋势.沙尘暴空间格局变动较频繁没有明显的移动趋势. |

| Abstract: | spatial distribution and annual variation tendency of dust storm with different strength grades in Xinjiang were studied through analysis of meteorological data of 54 weather stations in Xinjiang from 1960 to 2005. Results showed that the dust storm region of each strength grade was reduced year by year. The movement trend of flowing sand and dust storm region moved forward to the east, and the spatial pattern of floating dust showed retreated southward trend. The changes of the dust storm spatial pattern were frequent, but no significant movement trend was showed. |
