The study looked at how different types of land use affect soil erosion in the Yunmeng Lake watershed. Using remote sensing and GIS technology, researchers found that soil erosion has improved over time due to conservation efforts, but it is still a significant issue. Farmland had the most severe erosion, accounting for the majority of total soil loss. Grassland also showed high erosion levels. Residential land saw an increase in erosion area and amount. Overall, the findings highlight the importance of managing land use to prevent soil erosion and protect the environment.
