摘要:

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、华南和西南各省区,低适宜度区域主要分布在西北、华北和东南沿海的福建、江西等省区;最后,构建粮食生产布局协调指数作为我国不同区域粮食生产布局调整的依据,发现北方11个省区粮食生产布局过密,南方16个省区粮食生产布局过疏。研究方法具有一定的创新性,但是,在粮食生产适应性评价的指标选择等方面尚存在明显的不足,研究结果和结论都有待进一步完善。

Abstract:

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 of Southern Hills.Second,an evaluating index system including 7 indices are established,which mainly consists of 4 aspects:Water and land resources(particularly land),natural disasters and so on to quantitatively evaluate the suitability of food production in China.The evaluating results show that the suitability of food production in China also have notable regional discrepancy,which appears the lows of the value of the east is higher than that of the west.And highvalue regions mainly focus on the northeast,HuangHuaiHai,median China,south China and southwest,lowvalue regions mainly focus on northwest,north China,and southeast.Finally,an index of food production coordination was build to diagnose the layout of food production in China,it was found that the food production are intensive in 11 provinces in the north China,and the food production are thin in 16 provinces in the south China.The method used in this paper is innovative,but there also have some obvious deficiencies in this article such as the index system of suitability of food production.The research results and conclusions are deserved further improved.
