摘　　要：通过测算1997—2019年种植业及9种主要农作物生产的空间基尼系数、产业集中率和区位熵等指标,分析了种植业生产重心变化轨迹和空间自相关性,研究了中国种植业生产集聚的时间演变特征,以期为优化农业生产布局、调整农业产业结构以及提高农产品有效供给提供参考依据。结果表明:种植业总体上具有显著的生产集聚特征,但总体生产集聚程度呈现小幅度下降,生产重心向西北方向缓慢移动。9种农作物生产集聚程度的变化趋势和主产区的空间分布存在较大差异,呈现出专业化、连片化的集聚特征。棉花、糖料、麻类和烟叶生产集聚程度较高且呈上升趋势,茶叶、油料和蔬菜生产集聚程度中等且较稳定,水果生产集聚程度低并呈现下降趋势。粮食生产集聚程度低但呈现上升趋势,其空间正相关程度不断加强。山东、河南和安徽是我国种植业生产最重要的连片分布地区。Spatial Gini coefficient,the rate of industrial concentration,and location entropy of nine main crops production of planting industry from 1997to 2019were calculated,and the changing trajectory of gravity center and spatial autocorrelation of planting production were analyzed in order to study the temporal and spatial evolution characteristics of production agglomeration of planting industry in China,in order to provide a reference basis for optimizing the layout of agricultural production,adjusting the agricultural industrial structure and improving the effective supply of agricultural products.The results showed that the planting industry had significant characteristics of production agglomeration in China,but the overall degree of production agglomeration decreased slightly,and the gravity center moved slowly to the northwest during the study period.The changing trend of agglomeration of nine crops and the spatial distribution of the main production areas were quite different,and the production of crops presented the characteristics of specialization and contiguity.Production agglomeration degree of cotton,sugar,hemp and tobacco were higher and showed an upward trend,and tea,oil and vegetable were medium and stable,while fruit was low and showed a downward trend.Production agglomeration degree of grain was low but showed an upward trend,and was the only one which had the strengthening positive spatial correlation.Shandong,Henan and Anhui were the most important contiguous distribution areas of crop production in China.
