Fuzzy synthetical evaluation of meteorological disasters to Camellia Sinensis (L. O. Ktze) and its regionalization in Hubei Province

Meteological disasters are the main factors that restrict the production of Camellia Sinensis (L. O. Ktze) and affect the quality of Camellia Sinensis (L. O. Ktze). To evaluate the characteristics of spatial distribution of Camellia Sinensis (L. O. Ktze)’s meteorological disasters and their relationship with the meteorological elements in Hubei province comprehensively, this paper studied the disaster-causing factors and the classification of grade for the Camellia Sinensis (L. O. Ktze)’s freeze injury in overwintering period and dry-thermal injury between July and August, and then applied fuzzy synthetical evaluation model in fuzzy mathematics to analyze the spatial distribution of meteorological disasters to Camellia Sinensis (L. O. Ktze) in Hubei Province, based on the professional meteorological interpolation software ANUSPLIN. The results show that, it is quit different for the spatial distribution of Camellia Sinensis (L. O. Ktze)’s meteorological disasters in Hubei Province: the level of freeze injury in overwintering period to Camellia Sinensis (L. O. Ktze) in Hubei Province is gradually increasing from south to north, and the severe dry-thermal injury areas mainly lie in the central region of Hubei Province, while the mild dry-thermal injury areas locate in the vicinity of east and west sides of the severe dry-thermal injury areas. For; most parts of eastern and some areas in northwest of Hubei Province are the moderate dry-thermal injury areas. The comprehensive evaluation of Camellia Sinensis (L. O. Ktze)’s meteorological disasters can provide a theoretical basis to cope with Camellia Sinensis (L. O. Ktze)’s meteorological disasters and adjust the agriculture production layout of Camellia Sinensis (L. O. Ktze) in Hubei Province.
