摘　　要：根据阿克苏地区红枣不同时期低温冻害的情况,确定了红枣冻害的3种类型。在阿克苏地区10个气象站的冬季逐日气象资料和近年来枣树冻害资料的基础上,分析了气象因子对枣树冻害的不同影响。结果显示,阿克苏地区枣树冻害分布具有区域差异性,地区东部的枣树冻害严重、频次更高。枣树冻害主要与短时间的剧烈降温、低温长时间维持、高湿环境以及稳定积雪等气象因子关系密切,低温强度和低温持续时间是冻害发生的关键因子。Base on the freezing injury characteristics of jujube in low temperature of different period in Akesu Area, three types of jujube freezing injury was confirmed. Using daily data in winter from 10 weather stations and the jujube freezing injury data, this paper analyzed the influence of climate factors. The results showed that the spatial distribution of jujube freezing injury was different, the jujube freezing injuries were more severe and the frequency higher in the east .The jujube freezing injury was closely related to persistent low temperature, high humidity and steady snow cover, but the key factor was the intensity and duration of low temperature.
