| 摘 要： | 利用延安市1991—2020年13个国家气象站的年极端最低气温(冬季)、4月中旬～5月中旬(春季花期)的旬极端最低气温和109个加密区域站2008—2020年的年极端最低气温,以及2013—2020年4月中旬～5月中旬的旬极端最低气温观测资料,通过线性回归方法,进行数据订正延长和空间插值,并利用GIS技术,绘制樱桃冬季、春季花期低温冻害风险区划图。结果表明：国家气象站与加密区域站温度观测数据相关性非常好,可以得到加密区域站30a温度数据;温度受海拔高度、经度、纬度的共同影响,建立的多元线性回归方程通过0.001的可信度检验,计算出的温度分布呈现出沟壑区沟谷低山顶高的特征;区划结果为延川县中东部、延长县、宜川县以及宝塔区东部、黄龙县、洛川县、黄陵县为樱桃低温冻害低风险区;甘泉县、富县、宝塔区西部、延川县中西部、子长县南部、安塞区南部为樱桃低温冻害中风险区;吴起县、志丹县、安塞区北部、子长市北部为低温冻害高风险区。

| Abstract: | Using the annual extreme minimum temperature (winter), the decadal extreme minimum temperature from mid-April to mid-May (spring flowering period) of 13 national meteorological stations in Yan"an City from 1991 to 2020, and the annual extreme minimum temperature from 109 meteorological observation stations from 2008 to 2020, as well as the extreme minimum temperature observation data from mid-April to mid-May from 2013 to 2020 were corrected, extended and spatially interpolated by the linear regression method, and GIS technology was used to map the low-temperature freezing injury of cherries in winter and spring flowering period risk zoning map. The results show that: obtaining the temperature data from the weather observation station for 30a is possible, and there is a strong correlation between the temperature observation data from national meteorological stations and regional stations; the temperature is jointly influenced by altitude, longitude and latitude, and the multiple linear regression equation established can pass the confidence test of 0.001, and the calculated temperature distribution shows the characteristics of low valley and high mountain top in the gully region; the zoning results for the central-eastern part of Yanchuan County, Yanchang County, Yichuan County and the eastern part of Baota District, Huanglong County, Luochuan County and Huangling County are low risk areas for low temperature freezing injury to cherries; Ganquan County, Fu County, the western part of Baota District, the middle and western part of Yanchuan County, the southern part of Zichang County and the southern part of Ansai District are medium risk areas for low temperature freezing injury to cherries; Wuqi County, Zhidan County, the northern part of Ansai District and the northern part of Zichang City are high risk areas for low temperature freezing injury. |
