摘要
Abstract
Taking Hunan Province as an object,this study analyses the temporal evolution characteristics of grain production and its spatial pattern through methods such as data statistics and spatial autocorrelation.The results show that:(1)Grain production in Hunan Province has shown an obvious growth trend from 2000 to 2020.(2)County grain production is uneven in spatial distribution,with higher yields in Ningxiang,Xiangtan,Hengyang and other counties,while some counties have lower yields,which may be related to natural drivers,infrastructure and other factors.(3)There is a spatial agglomeration phenomenon of grain production in Hunan Province,and the analysis of Moran index confirms that the relationship of grain production among counties shows a positive spatial correlation.By revealing the spatiotemporal evolution characteristics of grain production in Hunan Province,this study provides references and suggestions for guaranteeing grain security,which is of great significance for stabilizing grain production and optimizing spatial distribution.关键词
