| Abstract: |
| By means of grey slope coefficient correlation degree and production function, the paperanalyzes main factors and growth contribution of grain production from 1980～2009. The result indicates that, from 1980～2009, the first three crucial factors impacting grain yield of Xinjiang region are agricultural machinery power, fertilization dosage and effective irrigation area; while viewing from the point of time, the influence of effective irrigation area and farming area are constantly strengthening, while the agricultural machinery power and fertilization dosage have experienced a change from strong to weak. |
