[Objective] This study aimed to analyze the relationships of the normalized difference vegetation index (NDVI) (1981-2006) in the desert-loess transitional zone of China with precipitation and temperature. [Method] The average method and the correlation function were applied in this study. [Result] The results indicated that dur-ing the growing season NDVI was positively correlated with precipitation in the cur-rent month, last month and the month before last, especial y the last month. NDVI mostly negatively correlated with temperature, especial y the temperature in the last month, which shows that the higher temperature, the more adverse the conditions for vegetation growth. [Conclusion] NDVI from August to October clearly is one of the significant factors influencing dust storm weather in spring of the next year.
