Abstract:It is very important to analyze and evaluate the benefit of meteorological service to all trades and professions for policy decision and taking precautions against meteorological calamities. In this study, profession meteorological service evaluation model was constructed, taking the experiences of other countries for reference. By applying this model, the position and function of the meteorological work in the whole national economy construction were analyzed, and the concepts, classification and characteristics of the meteorological service were studied, focusing on the basic thoughts of the benefit valuation of profession meteorological service. Also, basic methods to study the high meteorology-sensitive industry, and to determine the profession annual value ratio of production occupied by the high meteorology-sensitive industry were both established. Based on above work, the benefit of meteorological service to all Chinese high meteorology-hypersensitive industries were analyzed. Also, the profession annual value ratio of production occupied by the high meteorology-sensitive industry was obtained, and the benefit of the national profession meteorological service is initially evaluated through the expert valuation method (Dephi method). At the present level, the annual mean benefit of meteorological service is no less than 279 billion yuan.(The cost is not included).
