为研究我国区域粮食生产空间布局问题,运用虚拟耕地方法和对比方法对我国粮食生产空间布局进行诊断.首先,用人均农村人口粮食产量的虚拟耕地量表征我国粮食生产的空间布局现状,发现其存在"高值区相对集中,低值区相对分散",区域间差异明显的特点.高值区集中于东北和内蒙古,长江中下游以及江南丘陵的北部地区;其次,主要从水土资源,自然灾害等方面构建包含8个具体指标的评价指标体系对我国31个省级行政区的粮食生产适宜度进行定量评价.发现我国不同区域间的粮食生产适宜度存在显著差异,区域粮食生产适宜度整体上呈现东高西低的空间分布规律,其中,高适宜度区域主要分布在我国的东北,黄淮海,华中,华南...

In order to probe the problem of the spatial distribution of grain production in China,the method of virtual land analysis and comparison were used to diagnose it.The results are as follows：Firstly,the index of Per capita virtual land in regional food products by rural population was used to measure the spatial layout of food production in China,it was found that there are notable regional discrepancy of spatial layout of food production in China,and the high-value areas are concentrated in the northeast,Inner Mongolia,Yangtze River and north ...
