Its impacts include soil quality decline, vegetation destruction, soil erosion, urban ecological environment deterioration and other problems. With the acceleration of urbanization, urban soil erosion has become a serious environmental problem, posing a threat to urban sustainable development and the quality of life of residents. In order to effectively monitor and evaluate the impact of urban soil erosion, scientific researchers and environmental protection departments need to conduct real-time monitoring and dynamic evaluation of urban soil erosion, provide a scientific basis for urban land planning, ecological protection and environmental governance, and have important significance for protecting the urban ecological environment, improving land use structure and promoting urban sustainable development.
