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。
As a global environmental problem, soil erosion has drawn more and more attention. It is necessary to carry out dynamic simulation of soil erosion and forecast its development and evolution. It is of great significance for understanding soil erosion mechanism, predicting the trend of soil erosion and optimizing soil and water conservation Measures such as has a very important significance. This paper introduces the current research and application of soil erosion prediction models at home and abroad, and the status quo of CA model based on Cellular Automata (CA). It also points out the problems existing in soil erosion research based on CA and the research contents to be strengthened in the future.
