江西省粮食生产格局分析

Analysis of food production pattern in Jiangxi Province

依据粮食生产统计数据,运用时间序列、变异系数、地理联系率、区位熵等指标模型,分析江西省粮食生产发展及地域变化特征;利用规模优势指数、效率优势指数、综合优势指数模型对主要粮食作物进行生产地域优势分析。结果表明:(1)1978—2010年,江西省粮食总产量经历了"增长—波动—上升"过程;(2)粮食生产离散程度、区域差异均增大,"粮食产量—人口数"地理联系率总体呈下降之势,粮食生产向吉安、宜春与抚州等地区集中;(3)江西省粮食生产地域格局存在显著差异。最后提出了江西省粮食作物布局调整的建议。

According to the statistical data of grain production, with the index model such as time series, coefficient of variation, geography relation ratio and location quotient model, this article discussed the grain production and de- velopment and the change characteristics of the regional pattern in Jiangxi province. The regional advantages of eight kinds of grain crops in Jiangxi province was analyzed by scale advantage index, efficient advantage index and compre- hensive advantage index. It showed that grain production in Jiangxi Province experienced a process pattern of rising- stable-rising during 1978 to 2010. The discrete degree and regional difference increased, but the geography relation ratio of grain-yield ＆ population number declined, and Ji＇an, Yichun, Fuzhou and etc became the center of grain pro- duction. The significant difference exists in different production areas in Jiangxi. At last the suggestion for adjustment of grain crops pattern was proposed.
