摘　　要：根据农业气候条件的地区差异,研究辽宁省玉米种植气候区划的变化,规划辽宁省玉米种植和促进辽宁省玉米产业的可持续发展。研究结果表明,1961~2018年辽宁省农业气候资源在时间上呈现“降水减少、积温升高”的暖干化趋势。空间分布上呈现地域性差异,对辽宁省玉米气候区划因子进行指标划分,通过GIS得到近58年辽宁省玉米气候区划,分为最适宜区、适宜区和基本适宜区。从1961~1990年、1971~2000年、1981~2010年,基本适宜区和最适宜区呈现先增加再减小的趋势,适宜区呈现先减小再增加的趋势。Based on the regional differences in agro-climatic conditions to study the changes in the climate zon⁃ing of maize planting in Liaoning province,for the planning of maize planting and the promotion of sustainable devel⁃opment of maize industry in Liaoning province.The results showed that the agro-climatic resources in Liaoning province from 1961 to 2018 showed a warming and drying trend of"decreasing precipitation and increasing accumu⁃lated temperature".Climatic division factors of maize in Liaoning province were divided into the most suitable area,the suitable area,and the basic suitable area by GIS.From 1961-1990,1971-2000 to 1981-2010,the basic suit⁃able area and the most suitable area showed the trend of first increasing and then decreasing,and the suitable area showed the trend of first decreasing and then increasing.
