Based on the precipitation data of 203 township regional stations and 16 county (city) stations of national stations in southeastern Guizhou from 2010 to 2019, the temporal and spatial comparison analysis of precipitation, rainy day, rainstorm station times and extreme precipitation is carried out. The results show that the precipitation, rainy day and rainstorm of township regional stations have good correlation. With national stations α= 0.01 significance testing, it showed positive correlation and increasing trend;the annual precipitation presents a single peak type, a gentle rainy day and a bimodal rainstorm. There are certain differences in the magnitude of precipitation, the number of rainy days and rainstorms, and there are certain differences in the peak period, start period and end period of rainy day and rainstorm. The precipitation of regional stations in towns and townships is mainly distributed in two bands, with three large value centers. The rainy days and rainstorm concentration areas are distributed in a scattered and broken manner, and the extreme precipitation is distributed in bands, and the precipitation intensity is stronger than that of national stations. The precipitation, rainy day, rainstorm and extreme precipitation of the national station are distributed in flakes, and there are great differences in spatial distribution, dense areas and intensity. Therefore, the township regional stations can well reflect the distribution characteristics of precipitation caused by mountainous terrain.
