【摘要】：优化粮食生产布局、探讨粮食发展规律是有效调整农业空间结构、最大限度地提高土地生产效率的有效途径。以县域为单元,借用Open Geo Da中空间自相关和Arc GIS 10.2中地理加权回归探究了1995—2014年河南省县域粮食生产格局演化及影响因素。结果表明:(1)河南省粮食产量在全国粮食总产量中的比重总体呈现增长趋势;(2)县域粮食生产现状显示"东部多西部少"的分布格局,其粮食生产多集中分布在中东部平原区的产粮大县,县域粮食生产空间集聚性逐渐增强;(3)粮食生产的影响因素在不同的空间上具有不同的影响程度,且粮食生产朝低碳有机和规模化方向发展。
[Abstract]:Optimizing the distribution of grain production and discussing the law of grain development is an effective way to adjust the agricultural spatial structure and improve the efficiency of land production as much as possible. Based on spatial autocorrelation in Open Geo Da and geographical weighted regression in Arc GIS 10.2, the evolution and influencing factors of grain production pattern in counties of Henan Province from 1995 to 2014 were studied. The results show that the proportion of grain production in the whole national grain yield in Henan Province shows an overall increasing trend) the present situation of grain production in the county area shows the distribution pattern of "more in the east than in the west". Most of its grain production is concentrated in the big grain producing counties in the plain area of the central and eastern part of China. The spatial agglomeration of grain production in the county area is gradually enhanced.) the influencing factors of grain production have different influence degrees in different spaces. And grain production to low carbon organic and scale development direction.
