摘要
根据仁用杏花期受冻温度指标 ,对陕北各县仁用杏花期不同等级霜冻发生频率及由此造成的损失进行分析 ;以霜冻灾损率为指标对该地区仁用杏花期霜冻灾害气候进行风险区划。这对陕北各县种植仁用杏时综合考虑其灾害风险程度具有参考价值。
The frost frequency of apricot in different degree during flowering period and possible frost induced loss were estimated in the North of Shaanxi province, according to temperature index of apricot frost. The frost climatic risk division of apricot for this region was made, by using loss rate of frost. The results referred risk index of the frost disaster to the apricot planting of this region.
