Abstract Based on normalized difference vegetation index (NDVI) data, vegetation type data and meteorological data, this study revealed the warming trends of the day-and nighttime in growing seasons using the unitary linear regression analysis, and analyzed different effects of the asymmetry diurnal warming on vegetation activities using the two order partial correlation analysis method. Results indicated that:there was an extremely significant trend of diurnal warming from 1982 to 2013 in Xinjiang areas. The nighttime warming was approximately 1.5times that of daytime during growing seasons. The warming rate showed an asymmetry between day-and nighttime; the effects of day-and nighttime warming on vegetation activities showed obvious differentiation. Nighttime warming had significantly stronger and more extensive effects on vegetation than daytime warming; and different vegetation types responded differently to the asymmetry warming. Daytime warming had significantly positive effects on the coniferous forest, and nighttime warming had significant positive effects on the coniferous forest, agricultural vegetation, grassland, and meadow.
