摘要

动态模拟和预测土壤侵蚀的发育及演化过程具有十分重要的意义。传统土壤侵蚀模型从本质上来说是一种稳态模型

缺乏对土壤侵蚀发生、发展及演化过程的动态模拟能力。元胞自动机(cellular au-tomata

简称CA)是一种"自下而上"的动态模拟建模框架

具有模拟复杂地理系统时空演化过程的能力。利用元胞自动机理论和方法

提出了将CA应用于土壤侵蚀过程模拟的基本思想。以黄土高原丘陵沟壑区小流域为例

构建了基于元胞自动机的小流域侵蚀产沙过程模型。

Abstract

It is very important to dynamically simulate and forecast the development and evolution of soil erosion processes.The traditional soil erosion model is a steady-state model

which is not good at dynamically simulating the initiation and development of soil erosion processes.Cellular automata(CA) is a "from down to up" dynamic modeling framework

being capable to simulate the spatial-temporal evolutionary process of a complex geographical system.A basic thought that CA is applied to simulate soil erosion processes is put forward using theory and method of CA.By taking the loess hill and gully region as an example

a process model of soil erosion in small watershed based on CA is constructed.
