In order to investigate the spatiotemporal distribution characteristics of precipitation in the midstream region of a basin over recent years, this study collected precipitation data from 2013 to 2024. After rationality analysis of the data, mathematical methods were employed to analyze the temporal distribution, interannual variability, and spatial pattern of precipitation, as well as regional rainfall amounts. The results show that precipitation in the central basin is concentrated in June-September, with sharp seasonal contrasts and marked interannual differences. It alternates between wet and dry years, with a slow upward trend, though this trend is not statistically significant. Rainfall generally increases from the northeast to the southwest of the study area, with the highest annual rainfall exceeding 600 mm.
