Risk assessment of meteorological disasters of loquat planting in Xianning of Hubei based on GIS

The meteorological disaster is one of the most important factors affecting the large-scale planting and development of loquat. Taking the typical loquat producing areas in Xianning City of Hubei as an example, firstly, based on the investigation of planting situation and meteorological disasters in this areas in recent 10 years, combined with the observational data at the 6 national meteorological stations and the 135 regional weather stations in Xianning as well as the DEM elevation data of 30 m×30 m, we analyzed the disaster-causing factors and established the meteorological disaster index and its grade standard of loquat. Secondly, we constructed a comprehensive hazard assessment model of meteorological disasters by using the weight of each meteorological disaster hazard index calculated by Analytic Hierarchy Process. Finally, with the spatial distribution function of disaster probability established by the multiple regression analysis method combining the GIS technology, we conducted the evaluation and zo
