[Objective] The impacts of different plant patterns and configuration proportions on soil and water loss of an artificial slope were analyzed in order to provide reference for artificial slope vegetation restoration.[Methods] Natural rainfall from January to December 2019 was measured and the runoff and sediment yield characteristics for runoff plots was simulated using four different vegetation patterns to determine the runoff and sediment reduction benefits of different vegetation patterns.[Results] ① Total rainfall during the observation period was 1 053 mm, and total rainfall duration was 845.1 hours. Rainfall in July was the largest, and rainfall in February had the longest duration. Rainfall was concentrated in January to July, and classified mainly as moderate rain, heavy rain, and rainstorm. ② The variation in runoff yield per rainfall was large, and the variation in monthly and seasonal runoff yield was also large, mainly occurring in February-April and July, in events classified as moderate, heavy rain, and rainstorm. ③ The sediment yield of field rainfall, monthly rainfall and seasonal rainfall was very different. Sediment yield in March was the highest, and the sediment yield was concentrated in February-April and July, with frequent occurrences of moderate rain, heavy rain, and rainstorm events. ④ Compared with the flower-grass pattern, the shrub-grass pattern had the largest runoff reduction and the tree-grass pattern had the largest sediment reduction rate under each rainfall type. The tree-grass pattern had the largest sediment reduction rate, and the herb pattern had the largest runoff reduction rate under the monthly rainfall accumulation. The tree-grass pattern had the largest runoff and sediment reduction rate under the condition of accumulation of different rainfall classes and annual accumulation.[Conclusion] In the early stage of vegetation restoration, affected by the difference in vegetation coverage, the tree-grass pattern and the herb pattern had a higher rate of flow reduction and sediment reduction, and had better soil conservation benefits.
