According to the precipitation data of the central region of Inner Mongolia, the trend of precipitation changes were firstly analyzed in temporal and spatial evolution, and the correlation relationship between precipitation and average temperature, relative humidity, altitude, effective sunshine hours, green coverage area of built-up area were discussed then. The results showed that the precipitation decreased at first and then increased slightly in Ordos and Ulanqab while Baotou, Bayannur and Hohhot showed an irregular “W” in the inter-annual period, and the precipitation was mainly concentrated in July and August. In terms of space, the precipitation gradually decreased from the southeast to the northwest across the whole region, and it were greatly differences among cities. Through correlation analysis, we have identified the extremely association between the precipitation and average temperature, average relative humidity and effective sunshine hours in the study area.
