Abstract:Focusing on the Lingang New Area Dingke Community Science Park Landscape Project, the status of soil and water loss in the project area is deeply explored, and the current situation of soil and water loss and its main influencing factors are identified. Based on the prediction of the possible trend of soil and water loss, a targeted prevention and control system is proposed, and the prevention and control effect is predicted according to the prevention and control objectives of the project. The specific target value expected to be achieved after the implementation of the prevention and control measures is measured quantitatively and analyzed in depth. The results show that after the implementation of the measures, the indicators in the construction period and the design level year will reach or exceed the target value. The ecological benefits are good. The soil and water conservation system established on the basis of analyzing the soil and water loss, prevention and control measure system and benefits can effectively control the soil and water loss caused in the engineering construction, and promote the harmonious coexistence of engineering construction and the ecological environment, which provides important practical examples and theoretical reference for similar projects.
