[Objective] The trend of soil erosion in Qinghai Province from 2004 to 2023 and its driving factors were systematically analyzed， in order to provide a scientific basis for soil and water conservation in alpine regions. [Methods] By analyzing the soil erosion situation and conservation efforts in Qinghai Province from 2004 to 2023， and using correlation analysis， this study identified the changing trend of soil erosion area in Qinghai Province and its relationship with factors such as investment in soil and water conservation， supervision and management efforts， and the area treated by various control measures. [Results] The area of soil erosion in Qinghai Province decreased from 2.04×10⁵ km² in 2004 to 1.59×10⁵ km² in 2023. The proportion of moderately eroded area decreased from 22.5% to 11.4%， and the proportion of severely and above eroded area of the total eroded area decreased from 37.2% to 17.0%. Increasing investment in soil and water conservation funds and strengthening supervision and management were the main driving forces for the reduction of soil erosion area. [Conclusion] Overall， soil erosion control in Qinghai Province has shown a significant improving trend， with the soil erosion area decreasing year by year. However， there are still problems that need to be addressed. Soil and water conservation efforts have gradually shifted from generalized and extensive management across the entire region to targeted management in key areas. Future work will focus on regions affected by wind erosion and mild erosion. Additionally， the achievements of the control efforts will be consolidated， and the progression from mild erosion to severe erosion will be prevented. The establishment of a value realization mechanism of soil and water conservation ecological products should be accelerated， and the sustainable development of soil erosion control efforts should be established.
