| Abstract: |
| In order to calculate farmland production capacity, rationally exploit farmland productive potential and fully utilize the results of agrieultural land elassifieation, the farmland grain
potential production system was established. Based on this, natural productive potential, utilization productive potential and actual production capacity in Wugong County were calculated. The corresponding production potential was unit area times its corresponding quality index, and then summed up. The logistic model fitting the relationship between standard grain production and utilization quality index was used to calculate actual production capacity. The results showed that natural productive potential and utilization productive potential of Wugong County were 107.42×104 t and 70.05×104 t, respectively. The natural productive potential per unit area was 39.22t·hm-2 and utilization productive potential per unit area was 25.58t·hm-2. The actual production capacity was 28.49×104 t and actual production capacity per unit area was 10.40 t·hm-2. In spatial, cultivated land productivity per unit area in Wugong County showed significant gradient decrease distribution from southeast to nonhwest. Actual produetion capacity per unit area of Puji Town was the highest, 13.53 t·hm-2, and Youfeng Town had the lowest one, which was 8.66t·hm-2. |
