Based on the land use data of Kunming main city in 1980, 1990, 2000, 2010 and 2020 and the precipitation data of Kunming meteorological station in 1980-2019. Used anomaly analysis and Manner-Kendall methods to analyze land use changes and precipitation trends in the main urban area of Kunming. The results show that under the background of urbanization, the land use change in Kunming main city is obvious, and the construction land area is obviously increased. The annual precipitation level showed a downward trend, the annual precipitation days decreased significantly, and the extreme precipitation days increased. The change of land use has obvious influence on precipitation events.
