| Abstract: |
| Based on meteorological data (19712000) and geographical information data (1∶250000) , the climate division of cabbage rape was conducted in Zhangye by using the platform of Citystar. It was proved that the data layers were fairly accurate, and the relative error was less than 10% compared to the actuality. The results showed the possibility of digital and solid agricultural climate division and might provide scientific basis for local agricultural production. |
