Evaluation of Meteorological Service Benefits for Cold Water Fish Farming in Longyangxia
For meteorological services in cold-water fish farming,the evaluation of benefits is one of the techniques for judging forecasting capabilities.In order to improve the production efficiency of cold-water fish aquaculture and the ability to cope with meteorological disasters,taking the cold-water aquaculture in Longyangxia as the research object,this paper proposes an evaluation method for the benefit of meteorological services for cold-water fish farming,comprehensively analyzes the actual situation of the cold-water fish aquaculture area and the key influencing factors of meteorological services,selects eight evaluation indicators such as the accuracy of meteorological data and the increase and decrease of cold-water fish aquaculture production from the aspects of meteorological service quality and meteorological service performance,and constructs an evaluation index system for the benefit of meteorological services for cold-water fish farming.The attribute analytic hierarchy process model was used to calculate the weight of the evaluation index,and the benefit evaluation model was constructed by the reverse extrapolation method,and the unavoidable loss factors,meteorological service quality and performance index parameters were determined,and the evaluation value of meteorological service benefit was obtained.The results show that this method can effectively calculate the results of meteorological service benefit evaluation and obtain the input-output ratio of cold-water fish aquaculture,which has certain practical value in cold-water fish aquaculture.
