摘　　要：以2017—2020福州市9个气象站点逐日气象资料为基础,依据马铃薯生长周期、最适温度等特点,采用7—8月平均气温、7—8月降水量、7月降水量等气候要素为区划因子,运用GIS技术和小网格推算模型推算各气候要素,建立基于地理关系的马铃薯种植气候因子空间分析模型,推算各气候要素,订正气候区划指标残差,参照适宜指数区划福州市马铃薯农业气候,为福州市各区县春季马铃薯种植生产布局提供参考依据。Based on the daily meteorological data of 9 meteorological stations in Fuzhou City from 2017 to 2020,according to the characteristics of potato growth cycle and optimal temperature,three climatic factors including average temperature from July to August,precipitation from July to August and precipitation in July were used as regionalization factors,and the climatic factors were calculated by using GIS technology and small grid calculation model.The spatial analysis model of potato planting climate factors based on geographical relationship was established to calculate the climate factors,and the residual error of climate regionalization index was corrected.The potato agricultural climate regionalization of Fuzhou City was made with reference to the suitability index,which provided a reference basis for the spring potato planting and production layout of all districts and counties in Fuzhou City.
