Using the real-time precipitation observation data of 16 meteorological observation stations from 1961-2015 in the southeast of guizhou, counted the number of equivalent torrential rain days and rainy days, and analyzed the characteristics of climate change. The results show that the number of equivalent torrential rain days decreased in the southwest of Leigong mountain along the northeast, the number of rainy days was more in the east and west, and less in the south and north. The first mode of the number of equivalent torrential rain days was decreasing from northwest to southeast, the second mode was invert phase, along the southwest to northeast; the main mode of the number of rainy days was the center of the northwest to the east, decreasing outward, these distributions are affected by topography. The number of equivalent torrential rain days was increasing and changed frequently, The number of rainy days was decreasing and relatively stable from the mid-1960s to the early 2000s, then the trend goes down; They all had two year cycle change, the number of days of rain also had a long cycle of 11 years.
