摘要: 为了解城市气象灾害的年度和季节变化特征,以南昌为例,利用1954—2005年气象资料,对城市积涝、雷电、大雾、高温热浪、风灾和冰雪冻害等6种主要城市气象灾害的气象因子进行了统计和趋势分析。结果表明:南昌城市气象灾害具有明显的季节性,暴雨、大雾和高温热浪呈增加趋势,雷电、大风和冰雪的发生呈减少趋势。在分析城市本身致灾因素的基础上,提出了加强城市建设规划、改善城市大气环境和加强灾害监测与预警等对策建议。

Abstract: Six main urban meteorological disasters were analyzed in order to understand the annual and seasonal change characteristics of urban meteorological disasters,including waterlogging,thunder and lightning,heavy fog,high temperature heat wave,windstorm,ice and snow freeze injury,in terms of the disaster data in Nanchang from 1954 to 2005.The results indicate that urban meteorological disasters are of obvious seasonal characteristics in Nanchang.Rainstorm,heavy fog and high temperature heat wave are increasing,while thunder and lightning,windstorm and ice and snow freeze injury are decreasing.According to the factors causing disasters,some suggestions and countermeasures against meteorological disasters in Nanchang were put forward,including the plans to strengthen urban construction planning,to improve urban atmospheric environment quality and to enhance disaster monitoring and warning.
