【摘要】 为研究朔州地区藜麦种植的气候适宜性，利用朔州6个国家气象观测站1991—2020年的气象数据，对朔州地区平均气温、降水量、日照时数、平均最高气温进行分析，利用Excel和ArcGIS技术从空间上进行分析，通过数理统计、滑动平均及反距离权重法对各项指标进行插值，根据各因子适宜等级进行重分类及矢量叠加，得到精细化的的气象指标分布图层和藜麦种植气候适宜性区划图层。结果表明，朔州藜麦种植最适宜区域为平鲁区大部、朔城区西北部山区与平鲁相邻部分、山阴县中部较小的片区；次适宜区为山阴县和怀仁市的大部分区域，此区域有一项气象条件不利于藜麦产量的形成；不适宜区主要分布在右玉县、朔城区大部、应县，该区域有2个或2个以上的气象条件不符合藜麦生长发育及产量的形成。次适宜区和不适宜区必须有人工调节措施改善不利气象条件的影响才能推广种植藜麦，否则藜麦产量相比适宜区会有明显下降。更多还原

【Abstract】 The climatic suitability of quinoa planting in Shuozhou was studied based on the meteorological data of six national meteorological observation stations from 1991 to 2020. The average temperature, precipitation,sunshine duration and average maximum temperature from June to August in this region were selected as evaluation indexes and spatially analyzed by Excel and ArcGIS technology, and mathematical statistics,moving average and inverse distance weighted methods were adopted to conduct the interpolation of each index. The precise meteorological index distribution layer and quinoa planting climate suitability zoning map layer, namely most suitable area, sub-suitable area and unsuitable area, were subsequently obtained based on the reclassification and vector superposition of each factor according to its suitable level. The results showed that most of Pinglu District, the adjacent area of the northwestern mountainous area of Shuocheng District and Pinglu District, and a small part in the middle of Shanyin County were considered to be the most suitable areas for quinoa planting, and most of Shanyin County and Huairen City were classified to be sub-suitable area for quinoa planting due to one adverse meteorological condition in these areas. Two or more adverse meteorological conditions, which were unsuitable for the growth and yield formation of quinoa, were found in Youyu County,most of Shuocheng District and Yingxian County. To promote the planting of quinoa in the sub-suitable area and the unsuitable area, artificial adjustment measures must be applied to reduce the influence of adverse meteorological conditions, otherwise, the yield would be significantly affected compared with that of the suitable area.更多还原
