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广泛关注。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。元胞自动机(C e llu lar A u tom ata简称CA)是一种“自下而上”的动态模拟建模框架,具有模拟地理复杂系统时空演化过程的能力。从元胞自动机的概念和原理入手,介绍了CA模型的特征及其在土壤侵蚀学科中的应用情况和存在问题,对CA模型应用于土壤侵蚀过程的模拟、预测的可行性和可操作性进行了探讨。
As a global environmental problem, soil erosion has drawn more and more attention. Dynamic simulation and prediction of soil erosion development and evolution process is of great significance. Cellular Library (CA) is a “bottom-up” dynamic simulation modeling framework with the ability to simulate the spatial-temporal evolution of complex systems. Starting with the concept and principle of cellular automata, this paper introduces the characteristics of CA model and its application and existing problems in the soil erosion disciplines. The feasibility and operability of the CA model applied to the simulation of soil erosion process Discussed.
