| Abstract: |
| 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. |
