Abstract: To further explore the dynamic relationship between soil and water conservation measures and soil erosion processes, a coupled coordination model was introduced to empirically analyze the bidirectional feedback relationship between the two. The results showed that in the area of returning farmland to forests, every 10% increase in vegetation coverage could reduce soil erosion modulus by 15% to 20%. By constructing terraced fields and adjusting the slope gradient, the intensity of surface runoff could be significantly reduced, resulting in a 40% to 60% decrease in slope velocity. The coupling coordination analysis further revealed that in 2013, the study area showed synchronous development for the first time, and in 2022, the coupling coordination degree reached high-quality coordination, indicating a gradual trend toward synergistic development between water and soil conservation and soil erosion. Thus, it could be concluded that the reasonable implementation of soil and water conservation measures could not only effectively reduce soil erosion, but also narrow its impact range, providing scientific support for ecological restoration and environmental governance.
