摘要
目的分析研究陇县冰雹灾害的分布规律及灾害损失,为农业生产及防灾减灾提供依据。方法采用陇县公元193-2005年的冰雹灾害资料,结合实际调查,对冰雹灾害发生的时空分布特征、冰雹发生路径、冰雹直径以及冰雹所造成的灾害损失等进行分析。结果降雹的年、月、日变化、降雹直径及造成灾害的冰雹持续时间比较显著,20世纪90年代冰雹日相对少一些,但以重雹灾为主。结论影响陇县冰雹灾害的主要因素有地形、植被土壤和天气条件。
Aim The temporal-spatial distribution and disaster losses were analyzed to provide scientific basis for prevention disasters. Methods Based on the hailstorm climatic data from BC 193 to 2005 in Longxian County, Shaanxi, China, by actual research, the moving route, diameter, losses and characteristics of geographical distribution of hailstorm were discussed. Results The annual variation,monthly changes,daily changes of the hailstorm,diameter,and the average sustained time of hail disaster are significance. In 1990s the hail-fall days were relatively less, but all of them brought heavy damage. Conclusion The topography, vegetation, soil, and weather are main factors of impact on hailstorm.
