摘要
利用黑龙江省1971～2008年近40年的冰雹日数资料,分析了黑龙江省冰雹时空分布特征,着重讨论了黑龙江省冰雹日数年代、年、季、月、旬、日际变化,地域分布特征及黑龙江省前后20年冰雹的变化趋势,得出了黑龙江省冰雹的时空分布特征及其对农业生产的影响,提出了有效遏制冰雹灾害的防御措施。
The temporal and spatial distributions of hails were studied based on the data of the number of hailing days in Heilongjiang province from 1971 to 2008.In particular,the changes and geographic distribution characteristics of inter-decadal,inter-annual,quarter,month and day variations of hail days and the trend of hails during 40 years were analyzed.It concluded the effect on the agricultural production and some defensive countermeasures were put forward.
