In this paper, the parameters related to slope topography of the long-term test runoff plot of the four management models on steep slope area located in the head area of the Three Gorges Reservoir were observed and analyzed. The results showed that, compared with the control (wheat-peanut planting pattern), the interplanting of alfalfa hedgerows and Chinese toon hedgerows significantly reduced soil erosion, and slope terrain was significantly stepped along the hedgerow foundation. However, the effect of replacing ryegrass-grain amaranth was not stable on soil erosion control, and no difference was found compared with the control. The slopes treated with wheat-peanut interplanting alfalfa and Chinese toon hedgerows all formed hedgerows based on the hedgerows, the lower part of the hedges eroded strongly, and the phenomenon of silting and erosion on the hedgerows was obvious. Among them, the slope of the wheat-peanut interplanted Toon hedgerow plot formed a second-level hedgerow silt, with an average width of 420.8 cm, a relative height difference of 40.4 cm, and an average slope drop of 1.4 degrees. Wheat-peanut interplanting alfalfa plant hedgerows formed 4-level ridges with an average ridge width of 210.3 cm, an average relative height of 110.6 cm, an average slope length of 238.1 cm, and an average slope drop of 0.3 degrees. It shows that the hedgerow technology can reduce erosion and intercept silt, and significantly change the micro-topography. In view of the change of micro-topography, the sloping farmland interplanted with hedgerows should be transformed into terraces or cascaded slopes with complete irrigation and drainage facilities in the later stage. Using optimized plant varieties to design compound hedgerows interplanted with woody and herbaceous plants is expected to further improve soil quality. The distribution of the root system of the whole body, so as to stabilize the fence and control soil erosion. This study provides a reference for the optimization of follow-up management measures of hedgerow technology.
