摘 要: 气象灾害是制约茶叶生产并影响茶叶品质的主要因素,为综合评价湖北省茶树气象灾害的空间分布特征及其与气象要素的关系,以专用气象插值软件ANUSPLIN为依托,根据湖北省气象资料,选取出茶树越冬期冻害和7-8月旱热害致灾因子并划分受灾等级,运用模糊数学中的综合评价模型,重点分析了湖北省茶树气象灾害的空间分布特征。结果表明:湖北省茶树气象灾害的空间分布差异较为明显:湖北省茶树越冬期冻害等级由南向北逐渐增加;7-8月湖北中部地区为茶树重度旱热害区,位于其东西两侧附近区域为茶树轻度旱热害区,湖北东部的大部分地区和湖北西北部的局部区域为茶树中度旱热害区。茶树气象灾害模糊综合评价研究可为湖北省应对茶树气象灾害,调整茶叶生产布局提供理论依据。 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.
