Abstract:: In the context of increasing and intensifying extreme precipitation events,the study of the changes in the spatial and temporal patterns of extreme precipitation in small-scale regions is conducive to the overall regional assessment of the risks brought by abnormal precipitation. Based on daily precipitation data of from 12 general meteorological stations in Baise area in 57 years,we selected 9 extreme precipitation indexes,and used Mann-Kendall trend test and ArcGIS inverse distance interpolation to analyze the characteristics of spatiotemporal changes of extreme precipitation in Baise area from the aspects of sustainability index,absolute index,threshold index and intensity index.The results show that:from 1961 to 2017,the annual scale of extreme precipitation in Baise area as a whole showed a slight increase trend,the R₅₀,RX_{1 day},R_95p,SDII and CDD at annual scale all showed the increasing trend,other indexes fell slightly. Which indicated that the weak precipitation was decreasing and the heavy precipitation was increasing in Baise area, the number of dry days was also increasing, the precipitation tended to be intense and concentrated,precipitation tended to be extreme; the spatial difference of extreme precipitation at annual scale was obvious,and all the exponential spatial analysis results took Lingyun County as the maximum center, showing a pattern that the southeast region was dominated by an upward trend and the northwest region by a downward trend,which might be related to the special topographic factors in this region;the high frequency area of precipitation was mainly located around mountain ranges with topographic uplift and atmospheric convergence.These results can provide reference and support for water resources planning and disaster risk management in Baise area in order to reduce the impact of extreme disaster risk.
