分析了重大气象灾害服务效益评估的特点，构建了重大气象灾害服务效益评估模型、评估指标和评估流程，从气象预报准确率评估、预报服务覆盖率评估、政府决策部门反馈措施评估、服务效益综合评估报告等4个方面对重大气象灾害效益进行综合评估，以Asp.Net为平台开发出了基于B/S（Browser/Server）结构的重大气象灾害服务效益评估业务系统。并以2008年低温、雨雪、冰冻灾害为例进行了业务应用评估，为公共气象服务中针对重大气象灾害服务效益评估业务提供了工具。

The characteristics of benefit assessment of major meteorological disaster service are analyzed. The benefit assessment models, indexes, and working flow are constructed, and a comprehensive assessment is conducted in aspects of weather forecast accuracy, forecasting service coverage, feedback from government decisionmaking departments, and overall assessment of service benefits, and so on. The system is based on the Asp.Net platform and B/S (Browser/Server) structure of. Taking the low temperature and snow/freeze disaster of 2008 as an example, an operation application assessment is carried out with the system, which proved a useful tool for evaluating the benefits of major meteorological disaster service.
