开发建设项目水土流失预测结果是判别主体工程可行性或主体设计修改的重要依据 ,不同的设计阶段其预测内容、重点与方法、精度应有区别。各阶段预测的主要内容不仅是水土流失量 ,还应包括水土流失方式、危害等 ,在可行性研究阶段 ,这些内容更显重要 Prediction of soil and water loss in development and construction projects is an important basis for judging the feasibility of the main project or the design and modification of the main project. The content of the forecast, key points, methods and precision should be different in different design stages. The main content of each stage of prediction is not only the amount of soil and water loss, but also include the mode of soil and water loss, hazards, etc., in the feasibility study stage, these contents are more important
