坡面土壤水蚀建模方法比较

Comparison of Approaches for Water ErosionModeling on Hillslopes

首先阐述了坡面土壤水蚀建模的必要性。考虑到原有水蚀模型类型的不足 ,对当前水蚀模型按解题方法重新归为形式逻辑计算模型及辩证逻辑计算模型两类。其中 ,形式逻辑计算模型又分为经验模型、半概念半经验模型、半过程半经验模型以及理论模型 4类。

Firstly the necessity of water erosion modeling on hillslopes is discussed.Then existing water erosion models are generally divided into two types,formalization logic computational models and dialectical logic computational models(according to the way of solving problems)where the former can be further divided into four types——primarily empirically based,partially conceptually and partially empirically based,partially process based and partially empirically based,as well as theoretically based as weak points of the previous classification methods are concerned.Finally characteristics of each type and their relationships are illustrated by examples.
