In recent years, frequent extreme climate events have caused serious harm to social development, ecological construction and human health. The study on extreme climate events is of great practical significance. 14 extreme climatic indices closely related to the combination of water and heat, the growth of vegetation and the development of agriculture and animal husbandry were calculated based on daily data from 47 meteorological stations during 1960—2015 in Inner Mongolia Autonomous Region. The temporal and spatial variations and future trend of extreme climate events were analyzed by using regression tend, Mann-Kendall test, Sen's slope method and spatial statistical method. The results indicate that there is significant interannual fluctuations in the extreme temperature events in Inner Mongolia during the 56 years, the extreme high temperature index shows a significant upward trend, the extreme low temperature index shows a significant downward trend, and the increase of night time temperature is greater than the increase in the inter-turn temperature; the spatial variation characteristics of extreme temperature are not obvious, and the extreme temperature events in the east are slightly larger than those in the western region; the extreme precipitation index shows the insignificant decline overall, which indicates that the precipitation pattern in Inner Mongolia is relatively stable; in terms of spatial variation, the multi-precipitation index of the eastern and western stations is mainly rising, while it is dominated by the downward trend in the central region.
