摘　　要：采用经典的元胞自动机城市扩展与土地利用演化SLEUTH模型,改进元胞自动机控制系数的筛选方法,结合驱动力的研究调整模型控制系数,根据长江口北岸流域实际情况设置模型校准参数,提高模型在长江口北岸流域应用的实用性。研究表明SLEUTH模型方法可以获得精度较高的土地利用变化模拟结果。Using the classic cellular automata SLEUTH model of urban growth and land-use dynamic evolution,improved the screening methods of cellular automata control coefficient,adjusted the model control coefficient combining with the driving force and set the model calibration parameter according to the actual situation in the north branch of Yangtze River estuary to improve practical applications of SLEUTH model in the North Branch of Yangtze River Estuary.It is shown that SLEUTH model can obtain high precision result of land-use dynamic simulation.
