摘　　要：基于河北酿酒葡萄种植区代表性气象台(站)1961—2020年逐日气象资料,应用线性倾向估计、气候趋势系数等方法,明确了酿酒葡萄生育期农业气候资源对气候变化的响应特征。结果表明:近60年河北酿酒葡萄生育期平均气温、最热月均温呈升高趋势,21世纪以来的20年为近60年温度最高时期;日均温稳定通过10℃起始时间显著提前,结束时间推后,稳定通过10℃日数显著增加;≥10℃有效积温显著增加,每10年增加48.4℃;气温日较差呈减少趋势,6月显著减少;降水量显著减少,每10年减少11.3 mm,成熟期降水量和水热系数呈增加趋势,但降水日数呈减少趋势;日照时数波动减缓,每10年下降15.9 h。由此可见,气候变化对河北酿酒葡萄生育期农业气候资源产生了一定影响,热量资源增加为晚熟葡萄品种的成熟提供了保证,但春季晚霜冻发生风险加大。s:Based on the daily meteorological data of representative meteorological stations in Hebei wine grape growing area from 1961 to 2020,the response characteristics of agricultural climate resources to climate change during the growth period of wine grape were determined by using linear trend estimation and climate trend coefficient.The results showed that mean temperature of the hottest month and mean temperature of growth period of wine grapes in Hebei showed an increasing trend in the past sixty years,and 20 years have been the highest temperature period in the past 60 years since the 21st century.The start time of daily mean temperature stabilization at 10℃was significantly advanced,while the end time was delayed,and days of stabilization at 10℃were significantly increased.The effective accumulated temperature≥10℃increased significantly,and the climate tendency rate was 48.4℃per ten years.The diurnal temperature range showed a decreasing trend,and significantly decreased in June.The precipitation decreased significantly,and the climate trend rate was﹣11.3 mm per ten years.The precipitation and the hydrothermal coefficient increased at maturity,but the number of precipitation days decreased at maturity.The fluctuation of sunshine duration decreased,and the climate tendency rate was﹣15.9 h per ten years.This shows that the climate change has a certain impact on the agricultural climate resources during the growth period of wine grapes in Hebei region.The increase of heat resources provides a guarantee for the maturity of late ripening varieties,but the risk of late frost in spring increases.
