摘　　要：玉米生长发育和产量的形成与气象条件密切相关,气候波动是造成玉米单产不稳定的主要原因。以吉林省为研究区域,选取有代表性的20个地区,对各个地区玉米生育期内12个气象指标进行主成分分析,提取出2个主成分进行聚类分析,从而将吉林省划分为3个玉米种植生态区。利用GIS软件绘制出吉林省玉米气候适宜性区划图,并进行气候适宜度评价。Maize growth and yield formation are closely related to weather conditions.Climate fluctuations are the main reason for maize yield instability.This paper chose Jilin province as the study area,selected 20 representative areas,based on principal component analysis of 12 meteorological indicators of each region during the growth period to extract two principal components to do the cluster analysis.Jilin province was divided into three growing ecological zones,GIS software was used to draw climatic suitability of maize in Jilin province zoning map,and evaluated the climate suitability.
