【摘要】：[目的]为合理利用农业气候资源,主动适应气候变化提供依据。[方法]基于宁夏银川地区1961-2015年地面气象观测资料,明确了酿酒葡萄生长季内主要农业气候资源、影响酿酒葡萄品质的主要农业气候因子及主要农业气象灾害的演变特征。[结果]近55年银川日平均气温稳定通过10℃起始时间提前,结束时间显著推迟,日平均气温稳定通过10℃持续时间显著增加,每10年分别增加97.6℃和2.6d,尤其是1995年后积温出现了明显增加。近55年酿酒葡萄适宜的放条出土时间提前,可能的生长季呈显著延长趋势,生长季内热量资源显著增加。近55年酿酒葡萄全生育期内日照时数呈显著减少趋势,生育期内日较差均呈不显著的减少趋势,但在酿酒葡萄适宜生长范围内。最热月(7~8月)平均气温显著增加,每10年增加0.28℃,不利于酿酒葡萄优良品质的形成。酿酒葡萄采收前1个月(9月)降水量及降水日数表现为增加趋势,对品质形成不利。不同级别霜冻及越冬冻害发生频率有所减少。[结论]热量资源增加为晚熟品种的成熟提供了保证,但是霜冻及越冬冻害依然不容忽视。
[Abstract]:Objective to provide evidence for rational utilization of agricultural climate resources and active adaptation to climate change. [methods] based on the surface meteorological observation data from 1961 to 2015 in Yinchuan area of Ningxia, the main agroclimatic resources, the main agroclimatic factors affecting the quality of wine grape and the evolution characteristics of main agrometeorological disasters in the growing season of wine grape were determined. [results] in recent 55 years, the starting time and ending time of Yinchuan daily mean temperature stable passing through 10 鈩，
