- 摘要:
- 实践证明，在分析流域侵蚀产沙和预测发展趋势的研究中，选择一种既有理论依据，又能反映客观实际的计算方法是极其重要的。在众多类模型中，物理成因模型概念清楚，意义明确，应用方便，适应性强，是目前比较先进的模拟方法之一。鉴于土壤侵蚀产沙过程及环境因素的复杂性，该类模型也有需经改进的若干问题。
- Abstract:
- In the study of analyzing erosion and sediment production in watershed and predicting its development trend, it is important to choose a calculation method which is not only based on theory but also reflecting objective truth.And that is proved by practice.Among many types of model, the physical cause model is the more advanced one.Its function is specific, its application easier, and its adaptability extensive.Seeing that there is complexity in soil erosion and sediment production course and environment factor, it is necessary to improve the model.
