基于元胞自动机的土壤侵蚀过程CA模型研究评述

Soil Erosion Process Model Based on Cellular Automata

土壤侵蚀作为一个全球性的环境问题已经越来越受到人们的关注,开展土壤侵蚀的动态模拟和预测其发生发展及演化过程研究,对于深入认识土壤侵蚀机理、预测土壤侵蚀发展趋势及优化水土保持措施等具有十分重要的意义。介绍了目前国内外土壤侵蚀预测模型研究和应用以及基于元胞自动机的土壤侵蚀过程CA模型的研究现状,指出了基于CA的土壤侵蚀研究存在的问题和今后有待加强的研究内容。

Soil erosion is a global environmental problem.People has been paid more and more attention on soil erosion.It has important significance to study on dynamic simulation of soil erosion and predict the processes of its development and evolution for further understanding the mechanism of soil erosion,predicting the development tendency of soil erosion and optimizing the measures for soil and water conservation.The paper introduces the current study and application of soil erosion prediction model and soil erosion process model based on cellular automata both at home and abroad.It points out that the existing problems for researching soil erosion based on cellular automata and the contents should be strengthened future.
