摘要: 选取中国607个气象站1958−2019年逐日最低气温观测资料,运用统计和空间分析方法,从气候致灾的角度,对葡萄主产区春霜冻灾害发生日数、频率、站次比以及致灾危险性进行分析,以了解葡萄主产区春霜冻的分布特征和风险区域,为葡萄主产区灾害防御工作提供依据。结果表明,60a来,各葡萄产区春霜冻平均发生日数和频率差异较大,春霜冻发生频率和平均发生日数最高在西北产区和西南高山产区,最低在南方产区;研究期内葡萄主产区春霜冻发生范围呈缩小趋势,且轻霜冻发生范围大于中度和重度春霜冻;春霜冻发生强度区域性明显,其中,轻霜冻强度指数自北向南呈逐渐偏小的趋势,中霜冻和重霜冻强度指数普遍偏小;葡萄主产区致灾因子危险性指数空间分布特征表现为中北部普遍高于南部区域,其中高风险区域主要分布在西北产区和东北中北部产区,无风险区域主要分布在南方产区。

Abstract: In recent years, spring frost occurred frequently in China, which had a serious impact on grape industry and became one of the main meteorological disasters endangering grape production. Based on the daily minimum temperature observation data of 607 meteorological stations in China from 1958 to 2019, the occurrence days, frequency, station number ratio and disaster risk of spring frost disaster in main grape producing areas were analyzed by using statistical and spatial analysis methods. The results showed that the average days and frequency of frost in different grape growing areas were very different in the past 60 years. The frequency and average number of frost occurrence in spring were the highest in northwest and southwest mountain regions, and the lowest in southern regions. The intensity of spring frost was obvious in different regions. The intensity index of light frost tended to be smaller from north to south, while that of medium frost and heavy frost were generally smaller. The spatial distribution characteristics of the disaster causing factor index in the main grape producing areas were generally higher than those in the southern regions. The high-risk areas were mainly distributed in the northwest region and the north-east region, and the risk-free areas were mainly distributed in the southern region. According to the results of risk zoning, it can provide scientific basis for disaster prevention in main grape producing areas.
