Understanding the spatio-temporal variations of precipitation is crucial for regional water resources management and ecological environment protection in Loess Plateau. Based on daily precipitation observations from 292 meteorological stations across the Loess Plateau from 1960 to 2020, this study analyzes the spatio-temporal characteristics of precipitation amount, precipitation days, and precipitation intensity using the Mann-Kendall trend test and linear trend analysis. The results indicate that the long-term mean annual precipitation was 433 mm, with an average of 80 precipitation days and a precipitation intensity of 5.3 mm/day. All three indicators exhibited a decreasing spatial gradient from southeast to northwest. The number of precipitation days ranged from 36 to 134, dominating by the range of 60-100. Precipitation intensity varied from 3.1 to 9.1 mm/day, with the 6 mm/day isohyet showing a zonal distribution west of 111°E longitude. Over the past 61 years, the region has experienced an overall decreasing trend in precipitation amount, with a climatic tendency rate of -4 mm·(10a)-1. The number of precipitation days has also declined, whereas precipitation intensity showed no significant change. A pronounced spatial disparity in temporal trends is observed on both sides of the Linxia-Lanzhou-Qingyang-Yan’an-Taiyuan line, precipitation has generally decreased south to the line but increased north to it. The spatial pattern of precipitation indicators presented distinct interdecadal variations. The 1990s witnessed the most substantial decrease in precipitation days, while the 2010s saw increases in both precipitation amount and intensity. These findings highlight the complexity and regional heterogeneity of precipitation changes across the Loess Plateau, which can provide a scientific basis for water resources management and climate change adaptation in the region.
