摘要/Abstract

摘要： 选取黄土高原酿酒葡萄产区13个气象站点1981−2020年春霜冻期（4月1日−5月31日）逐日最低气温观测资料，运用数理统计和空间分析方法，研究不同年代黄土高原酿酒葡萄春霜冻灾害发生站次比、频率、日数、强度及风险，评估黄土高原酿酒葡萄春霜冻气候风险。结果表明：1981−2020年，黄土高原酿酒葡萄春霜冻期平均日最低气温呈极显著上升趋势（P＜0.01），气候倾向率为0.42℃·10a⁻¹；日最低气温极小值呈极显著下降趋势（P＜0.01），气候倾向率为−0.75℃·10a⁻¹；日最低气温极小值的气候倾向率负值主要分布在产区北部或南部零星地区，左权地区降温（0.76℃·10a⁻¹）达显著水平（P＜0.05）。黄土高原轻度春霜冻发生站次比下降，中度、重度及综合春霜冻上升；轻度、中度春霜冻频率和日数降低，重度春霜冻频率、日数增加，且重度春霜冻强度呈显著增加趋势（P＜0.05），春霜冻综合频率、日数降低，强度呈显著增加趋势（P＜0.05）；各级春霜冻频率、日数、强度自西南向东北增加。黄土高原酿酒葡萄气候风险特征为轻、中度春霜冻的风险降低，重度和综合风险增加；高风险区域主要分布在北部的左权、太古等地，低风险区域主要分布在南部的鄠邑区、渭南等地。

Abstract: To assess the climate risks of spring frost on the Loess Plateau, the daily minimum temperature observation data during spring frost period (April 1-May 31) from 1981 to 2020 for 13 meteorological stations on the Loess Plateau grapevine area were collected, and the station ratio, frequency, number of days, intensity and risk were studied by mathematical statistics and spatial analysis methods. The results showed that during the spring frost period of grapevine on the Loess Plateau from 1981 to 2020, the average daily minimum temperature showed a highly significant upward trend with 0.42℃·10y⁻¹ of climate tendency, the lowest daily minimum temperature showed a highly significant downward trend with −0.75℃·10y⁻¹ of climate tendency. The negative climate tendency rates of lowest daily minimum temperature were distributed sporadically and the higher absolute value was in Zuoquan with −0.76℃·10y⁻¹. The station ratio of slight spring frost on the Loess Plateau decreased, while the moderate, severe and comprehensive spring frost increased. The frequency and number of days of slight and moderate spring frost decreased, while the severe spring frost showed increased, and the intensity of severe spring frost showed a significant upward trend; the comprehensive frequency and number of days of spring frost decreased, while the intensity showed a significant upward trend. The frequency, number of days, and intensity of spring frosts increased from southwest to northeast for all spring frost levels. The climatic risk of grapevines on the Loess Plateau decreased in the risk of slight and moderate spring frosts, and increased in the risk of severe and comprehensive spring frosts. The high-risk areas were mainly distributed in Zuoquan, Taigu and other places in the north, and the low-risk areas were mainly distributed in Huyi and Weinan in the south. The results could provide a scientific basis for the prevention and mitigation of grapevine spring frost on the Loess Plateau.
