Abstract

Abstract: For the meteorological disaster prevention and reduction service of rainstorm disaster, through the expert questionnaire survey, based on the analytic hierarchy process and delphi method, the benefit evaluation index system for meteorological disaster prevention and mitigation services for rainstorm disasters was established, and the weight coefficient of each evaluation index was determined. On the analysis and evaluation data of typical cases of heavy rain weather services in Hunan province in recent years, following the principle of quantification and easy access, the specific evaluation methods for various indicators were proposed. By comprehensively using the evaluation index system and the evaluation method of each index, a trial evaluation of the effectiveness of meteorological disaster prevention and mitigation services was carried out for a typical heavy rain process in Hunan province from June 30 to July 5, 2015. It was concluded that the comprehensive service benefits of meteorological disaster prevention and mitigation of this rainstorm was 0.88, indicating that the service benefit of meteorological disaster prevention and reduction was significant.

Key words: rainstorm disaster, meteorological disaster prevention and mitigation service benefit evaluation, analytic hierarchy process, delphi method, index system
