摘要:
细沟侵蚀作为由面蚀向沟蚀转化的重要环节，是坡面水蚀物理过程的一个重要组成部分，在坡面侵蚀产沙机理研究中具有重要意义。传统侵蚀模型很难精确地动态模拟和再现这一自组织现象的形成过程。元胞自动机是一种“自下而上”的动态模拟建模框架，通过元胞间的相互作用，能够在整体上表现出许多复杂的非线性行为和现象，具有模拟复杂地理系统时空演化过程的能力。运用元胞自动机理论和方法建立了黄土坡面细沟侵蚀时空演化过程模型——CA-Rill，对坡面细沟发育过程进行了动态虚拟实验，生动地模拟了坡面细沟自组织形成过程，并对结果进行了分析。研究突破传统试验方法的束缚，为细沟侵蚀研究提供了新的途径。
Abstract:
Rill erosion is an important link on the transition from sheet erosion to gully erosion,and is an important component of water erosion physical process on hillslope.Rill erosion research is of great importance to comprehend erosion and sediment mechanism on slope surface.Traditional erosion model is difficult to accurately dynamic simulate and reproduce rill initiation and development process on slope,and this process is self-organizing.Cellular automata,simple named ‘CA’,is a ‘from down to up’ dynamic modeling framework.It is able to simulate the spatial-temporal evolutionary processes of complex geographical system.By interaction between one cell and another,CA can show a great deal of complex non-linear action and phenomena as a whole.CA-Rill,a rill erosion dynamic model on loess slope,is constructed by use of theory and method of cellular automata.The dynamical virtual experiment is carried out for rill self-organizing process on slope.A rill initiation and development process is simulated vividly.The experimental results are analyzed.This research is a breakthrough in traditional test approach,and gives us a new way for researches in rill erosion.
