采用柳州市2000、2010年ETM+遥感影像，基于CART决策树分类方法提取景观类型分布信息，运用景观生态学原理和景观指数分析方法，通过ArcGIS 9.3和Fragstats 3.3软件分析了柳州市景观类型和格局的演变。结果表明，柳州市景观多样性指数较高，各景观类型面积分布较均衡，景观结构组成较为复杂。林地景观和耕地景观构成柳州市的景观基质，10年来，耕地景观减少，林地、工矿居民地、水域和未利用地均有不同幅度的增加，而耕地和工矿居民地景观受人为干扰严重，需要加强管理与规划。

Based on the Landsat ETM+ image from 2000 to 2010 of Liuzhou city, the distributed information of landscape types was extracted through classification and regression trees (CART) method. The dynamics of landscape types and patterns were analyzed by the principle of landscape ecology and landscape indexes analysis by Fragstats3.3 and ArcGIS9.3. The results showed that the Liuzhou city had high landscape diversity index, balanced distribution of various landscape types and complicated landscape structure. Forest and farmland landscape were the landscape matrix in Liuzhou City. From 2000 to 2010, farmland landscape decreased, while forest land, residential and industrial land, water and unused land increased in different scales. The farmland, residential and industrial landscape were disturbed seriously by mankind, which need to be managed and planned intensively.
