中文摘要	[目的]分析黑河流域中游荒漠区沙尘暴、扬沙以及浮尘频次和时长的月变化和年变化,并分析其与主要气候因子的关系,为区域沙尘天气的早期预警和荒漠区的经营和管理提供依据。[方法]利用黑河流域红沙窝荒漠化综合防治试验站的20102019年的沙尘天气监测数据和气象数据进行分析。[结果]沙尘频次和时长主要集中在春季,其次是冬季,春冬两季的频次和时长各占全年的82.3%和79.4%。10a间沙尘暴和扬沙频次总体变化趋势逐渐减少,而浮尘频次总体变化趋势逐年增加;沙尘时长总体变化趋势逐年增加。沙尘频次月变化与土壤湿度(10cm)和大气湿度之间呈极显著负相关(p<0.01),与风速之间呈极显著正相关(p<0.01)。扬沙年际发生频次与土壤温度(5cm)之间呈显著负相关(p<0.05),与大气温度之间呈极显著负相关(p<0.01)。[ 结论]近10a来,黑河流域中游荒漠区的沙尘天气主要发生在春季和冬季,破坏性较大的沙尘暴和扬沙逐年减少,而浮尘逐年增加。沙尘频次的月变化主要影响因素是浅层土壤湿度、大气湿度和风速。春季的浅层土壤湿度影响了沙尘暴和扬沙年际频次变化,浅层土壤温度影响了浮尘年际频次变化;冬季的浅层土壤温湿度和降水量影响了沙尘暴的年际频次变化,浅层土壤温度和大气温度影响了扬沙的年际频次变化。
英文摘要	[Objective]The monthly and annual changes,the frequency and duration of dust storms,fly sand, and floating dust,and the relations between these and the main climatic factors in the desert area of the middle reaches of the Heihe River basin were analyzed.The aim was to provide a basis for the early warning of sand and dust weather,and the operation and management of desert areas.[Methods]The monitoring data and meteorological data of dust-related weather during 20102019from the test station of desertification control of Hongshawo desert area in the Heihe River basin were used.[Results]Dust storms and fly sand weather were more frequent and longer in spring,followed by winter.The dust-related weather in spring and winter accounted for 82.3%and 79.4%of the frequency and length of these weather phenomena,respectively, across the whole year.In the past 10years,the overall frequency of dust storms and fly sand gradually decreased,whereas the frequency of floating dust increased year by year,as did the duration of floating dust. The monthly variation in the frequency of floating dust weather was negatively correlated with soil moisture (10cm depth)and atmospheric humidity(p<0.01),and positively correlated with wind speed(p<0.01). The annual occurrence frequency of sandstorm weather was negatively correlated with soil temperature(5cm depth,p<0.05)and significantly negatively correlated with atmospheric temperature(p<0.01).[Conclusion]In the past 10years,sand and dust weather events mainly occurred in spring and winter in the desert area of the middle reaches of the Heihe River basin.The more destructive sandstorms and sand movements decreased over this period,whereas floating dust increased year by year.The main factors influencing the monthly variation in sand and dust weather frequency were shallow soil moisture,atmospheric humidity,and wind speed.The shallow soil moisture in spring affected the interannual frequency changes of sandstorms and raised dust,and the shallow soil temperature affected the interannual frequency changes of floating dust;the shallow soil temperature,humidity,and precipitation in winter affected the interannual frequency changes of sandstorms,whereas shallow layer soils and atmospheric temperature influenced the annual frequency change of fly sand.
