【Objective】The Three Gorges Reservoir area, as a typical key region for soil erosion in the Yangtze River Basin, has received widespread attention. However, the differential responses of surface runoff and sediment production to rainfall typologies in the Three Gorges Reservoir Area remain underexplored. 【Method】This study systematically analyzed runoff-sediment dynamics in relation to land use and rainfall characteristics using a comprehensive 3-year dataset (2021-2023) from the Fugou experimental watershed in Wanzhou District, Chongqing, which includes 108 rainfall-runoff events monitored from 8 natural full-slope and 1 standard bare slope plot (as control), representing typical landforms in the Three Gorges Reservoir area. The area of the full-slope plots in this study ranges from 407 to 1539 m2, with slopes between 14° and 25°. The standard runoff plot has an area of 100 m2 and a slope of 15°. All plots were characterized by purple soil, while the surface coverage of other land-use plots ranged from 73% to 85%. 【Result】The results showed that: (1) During the observation period, rainfall was primarily classified into three types: Type A (low frequency, long duration, heavy rainfall amount, moderate rainfall intensity), Type B (medium frequency, short duration, moderate rainfall amount, heavy rainfall intensity), and Type C (high frequency, medium duration, light rainfall amount, light rainfall intensity). Among these, Type C exhibited the highest frequency in the study area, while Type A was identified as the principal rainfall type inducing slope runoff and sediment yield. The critical rainfall intensity and maximum 30-min rainfall intensity triggering erosion on bare slopes were 3.60 times and 1.41 times those of the other land use plots, respectively. (2) The multi-year average runoff and sediment yield from bare slopes were 2.63 to 4.03 times and 5.71 to 9.84 times those of the other land use plots, respectively. Sediment production in cropland and arboreal woodland showed the highest sensitivity to Type A rainfall events, whereas grassland sediment yield was most sensitive to Type C rainfall. Bare slopes and shrubland sediment yields demonstrated peak sensitivity to Type B rainfall. (3) The contribution of rainfall types to runoff and sediment yield from bare slopes and the other land use plots was influenced by the land use types. The impact of rainfall types on runoff generation from bare slopes was weaker than that on the other land use plots, but their influence on sediment production exceeded that of the other land use plots. Also, the average runoff reduction efficiency and sediment reduction efficiency of the other land use reached 72.13% and 98.72%, respectively. Grasslands demonstrated higher sediment reduction efficiency than other measures, and the maximum runoff-sediment reduction benefits of conservation measures occurred during Type B rainfall events. Analysis of variance contribution rates revealed the following order of influence on slope runoff and sediment yield: land use (50.30%~70.37%)> rainfall type with land use (0.30%~5.70%) > rainfall type (23.93%~49.40%) in descending order. In addition, the impact of rainfall patterns on slope runoff and sediment yield was significantly influenced by land use.【Conclusion】The results indicate that implementing soil erosion control in the Three Gorges Reservoir Area requires comprehensive consideration of rainfall characteristics to deploy targeted measures. Simultaneously, it is proposed that when implementing comprehensive soil and water conservation management in the study area, appropriate measures should be identified under the premise of considering the regional climate. These findings provide a scientific basis and practical guidance for soil erosion prevention and control in the study area.
