| Abstract: | Based on the analysis of atmospheric temperature records in Shaanxi-Gansu-Ningxia border area in recent 50 years, It is believed that the climate is getting warmer and drier in the Shaanxi-Gansu-Ningxia border area. Since the 1990s, the trend of getting warmer and drier has been accelerated, especially the intensity and frequency of drought have increased. In view of the trend of climate vulnerable changes, the strategy for environmental construction is put forward. |
