中文摘要	民勤荒漠区沙尘暴发生日数在波动中表现为减少趋势。为了研究探索沙尘暴减少的原因,运用1956年以来的沙尘暴观测资料、1961年以来的气象资料和1974年以来的植物物候观测资料,用标准差计算沙尘暴的月变差,用相关系数计算空气湿度等气候要素和植物物候与沙尘暴发生日数之间的相关关系。结果表明,沙尘暴日数的减少与空气相对湿度的增大密切相关,与春季植物物候的提前和秋季植物物候的推迟之间存在一定的相关关系。植物物候变化与沙尘暴发生日数变化的关系有待深入研究。
英文摘要	The frequency of sandstorms has showed a decreasing trend with fluctuations in the Minqin desert area.In order to explore the reason for that,based on observations of sandstorms since 1956,and measured data of plant phenology since 1974,monthly variation of sandstorms was calculated with standard deviations while correlation between the frequency of sandstorms and climatic elements such as air humidity as well as plant phenology was computed with correlation coefficients.Results show that reduction in frequency of sandstorms is highly correlated with an increase in air humidity and has a certain relationship with advancing and postponing of plant phenology in spring and autumn respectively.The conclusions of this kind have not been reported so far at home and abroad.In particular,the relationship between the frequency of sandstorms and changes in plant phenology is a new finding,which needs to be verified by research in other regions.
