| 中文摘要: |
| 以县域为基本空间单元,运用塞尔指数和GIS方法分析了黑龙江省粮食生产的空间格局及其区域差异,并基于20002007年42个典型县域粮食生产的面板数据建立多元回归评估模型,探讨该省粮食生产区域差异的成因。研究结果表明:(1)黑龙江省粮食生产主要集中于省域东部、南部和西部,三大片区行政面积约占全省的46%,粮食总产量约占全省的80%。(2)2000年以来,全省及三大片区内部各县域粮食生产的区域差异逐渐由波动趋于相对稳定。(3)化肥使用量、农村用电量、耕地面积比重、农村居民人均纯收入、除涝面积是黑龙江省粮食生产区域差异扩大的主要原因,而耕地面积、水库容量则在一定程度上缩小了区域差异。 |

| Taking counties as the basic spatial unit, by the methods of GIS spatial analysis and Theil index, the regional differentiation and its variation character of grain production in Heilongjiang Province were discussed. Moreover,
based on the panel data of grain production of 42 typical counties in the years of 2000~2007, an evaluation model was established to explain the driving factors and regional differentiation of grain production in Heilongjiang. The resuls show that: (1) Grain production are mainly centralized in the eastem, southem and westem areas of Heilongjiang. The three areas cover about 46% of the total area of Heilongjiang, but its percentage of grain yield is more than 80%. (2) Since 2000, regional differentiation of grain production in Heilongjiang and the three major areas has been changing from unsta-ble to stable. (3) Consumption of chemical fertilizers , electricity consumed in rural areas, the percentage of cultivated land of regional area, per capita annual net income of rural residents and area with flood prevention measures have posi-tive effects on the expansion of Heilongjiang ' s grain production change, and cultivated area and the capacity of reservoirs can narrow the regional differentiation of its grain production. |
