摘　　要：文章利用拐子湖气象站1991-2021年沙尘暴气象观测资料,选用线性趋势分析法,对该地沙尘暴天气变化规律进行分析。结果表明:近31年拐子湖年沙尘暴日数整体以下降趋势为主,气候变化倾向率为-3.524d/10a,下降趋势极为显著;拐子湖年内沙尘暴日数主要出现在每年的3-7月,平均每月的沙尘暴日数几乎都在1.5d以上,尤以4-6月最为集中,这种春夏频繁型的分布特点与拐子湖的气候特点、地理位置及地面状况密切相关。This article uses the observational data of sandstorms at the Guaizihu Meteorological Station from 1991 to 2021,and uses the linear trend analysis method to analyze the changes in sandstorm weather in the area.The results show that in the past 31 years,the number of annual sandstorm days in Guaizi Lake has shown a significant downward trend,with a climate change trend rate of-3.524d/10a,which is extremely significant;the number of sandstorm days in the year of Guaizi Lake mainly occurs from March to July each year,with an average of over 1.5 days per month,with April to June being the most concentrated.This frequent distribution pattern in spring and summer is closely related to the climate characteristics,geographical location,and ground conditions of Guaizi Lake.
