中文摘要: 以冬小麦的风雹灾害为研究对象，从1981～1990年33个冰雹个例中选取与冬小麦生长有关的17个个例，以冰雹直径、降雹时间、降雹时阵风为因子，对冬小麦风雹灾害进行等级划分及灾情评估。应用证明，这些研究对提高农业灾害的管理水平具有重要意义。
中文关键词: 冬小麦，风雹灾害，灾情评估
Abstract:17 cases relating to winter wheat growth were selected from among 33 hail events during 1981 to 1990. The wind and hail disaster of winter wheat was studied. The hail diameter,the duration of hailfall and the gust during hailfall were used as the factors,the classification and assessment of wind and hail disaster were conducted.
