摘　　要：基于统计分析、GIS空间分布方向性分析、时序变化趋势分析等方法,分析了1985—2022年吉林省主要农作物种植结构的时空格局演变趋势.结果表明:近40年吉林省农作物种植面积呈上升趋势,农作物种植类型以玉米、稻谷、大豆、油料、蔬菜为主,总体上均呈现西北-东南的空间分布格局;1985—2022年吉林省出现了8种农作物种植结构类型,吉林市、松原市、白城市和延边朝鲜族自治州进行了农作物种植结构类型调整,粮食作物的种植比例增加;从类型丰富度来看,1996—2022年吉林省农作物种植结构类型丰富度呈先增后减、整体下降的趋势,最大值为0.75,出现在2002年.研究结果可为吉林省农作物种植结构理论优化提供理论依据.Based on statistical analysis,GIS spatial distribution direction analysis,time series change trend analysis and so on,this paper analyzes the spatiotemporal pattern evolution trend of the main crop planting structure in Jilin Province from 1985 to 2022.The results show that the crop planting area in Jilin Province has shown an upward trend in the past 40 years.The crop planting types are mainly corn,rice,soybeans,oil crops,and vegetables,which they show a northwest-southeast spatial distribution pattern;From 1985 to 2022,8 types of crop planting structures appeared in Jilin Province.Jilin City,Songyuan City,Baicheng City and Yanbian Korean Autonomous Prefecture made adjustments to the crop planting structure types,and the proportion of food crops planted increased;From the perspective of type richness,the type richness of crop planting structure in Jilin Province from 1996 to 2022 showed an overall downward trend of first increasing and then decreasing,with the maximum value appearing in 2002,which was 0.75.The research results can provide theoretical basis for the theoretical optimization of crop planting structure in Jilin Province.
