| Abstract: |
| Based on the yield and climate data in rainfed farming areas of Gansu,the variations of climate and yield were analyzed,and the vulnerability of autumn grain crops in these areas was estimated.The results showed that the climate represented to become warmer and drier in recent 40 years,which was disadvantageous to productivity increase.In the areas where the weather factors strongly fluctuated,the production of autumn grain was very vulnerable.The strong vulnerable areas were eastern part of Longdong and northern part of Tianshui. |
