根据香格里拉县的区域特点，确定了香格里拉县的森林景观分类系统。通过对1989、1999年和2009年三期 Landsat TM 遥感影像的解译和验证，得到森林景观格局图。利用 CA－Markov 模型对2009年森林景观格局进行模拟，模拟结果与实际景观格局的 Kappa 指数为0．7832，具有较高的可信度。再利用该模型对香格里拉县2019年森林景观格局进行模拟，结果表明：2009—2019年香格里拉县景观类型变化明显，高山草甸、农地、未利用地面积减小速度有所减缓，主要转换为建筑用地、其他乔木、落叶松、栎类；云冷杉、高山松、栎类、云南松、落叶松、其他乔木、灌木林地、其他林地、建筑用地、水域面积持续增大，前4类优势树种年均增长幅度分别为0．24％、0．18％、0．46％、0．07％。政府部门应继续加大对过度放牧的管制和制定合理的森林资源保护政策，从而更好的保护香格里拉县森林生态环境。

@@@@A forest landscape classification system was established considering the regional characteristics of the Shangri-La County.Three periods of forest landscape pattern map were got by classifying and validating by using Landsat TM images of 1989, 1999 and 2009.The 2009 landscape pattern of Shangri-La was simulated based on CA-Markov model.The simula-tion result had high reliability with the Kappa coefficient of 0.783 2 in comparison with actual situation.Then, the model was used to simulate the 2019 forest landscape pattern.The result shows the 2009-2019 landscape patterns of Shangri-La County changes obviously.The Shangri-La County alpine meadows, agricultural land and unused land decrease slowly and mainly convert to building land, trees, larch and the oak.Spruce-fir, mountain pine, oak, Yunnan pine, larch, other ar-bor, shrubs, other woodlands, building land and water area increase steadily.An average annual growth rate of the first four categories of dominant tree species are 0.24%, 0.18%, 0.46% and 0.07%.The government should continue to control overgrazing and develop reasonable protection policy for forest resources for better protecting the forest ecological-.
