| 摘 要： | 采用陕北25个县气象站观测的气象资料和陕北6县仁用杏物候资料，对陕北仁用杏气候生态条件进行了分析。以≤0℃终日、≥10℃积温、年降水量为区划指标，运用GIS地理信息系统做了陕北仁用杏气候适宜性区划。结果表明:陕北各地均可种植仁用杏，但种植目的应有差异。在仁用杏气候最适宜区，仁用杏生长发育最为适宜，可获得较高且稳定的经济效益，主要分布于陕北东部黄河沿岸；在仁用杏气候适宜区，种植仁用杏部分年份发生冻害，能基本保证获得较好的经济效益，主要分布在陕北中南部、长城沿线风沙区中部及西部；在仁用杏气候较适宜区，仁用杏开

| Abstract: | Based on an analysis of clim-ecology adaptability for apricot in northern Shaanxi,using the climatic data from 25 counties and the apricot phenology data from 6 counties in this region,the division indexes were determined as last day with the temperature ≤0℃,accumulate temperature of ≥10℃ and annual precipitation.The division indexes were calculated in net squares,and piled up in GIS(city star) by different grade standards.The GIS-based division picture for apricot in northern Shaanxi is made,and commented on different districts. |
