摘　　要：基于实际调查和森林资源二类清查数据,将川东北秦巴山地光雾山彩叶景观划分为13类,利用Arc GIS技术和Fragstats3.3(栅格版)分析软件,对其彩叶景观格局进行定量分析。结果表明:研究区彩叶景观整体具有较好的稳定性、丰富度和聚集度。面积最大的桦木彩叶景观,破碎化程度最低,而面积较少的厚朴等显示出较高的破碎度;其余类型各指数差异均不明显,破碎化程度处于中间水平。该结果为光雾山彩叶景观资源的旅游开发利用和管理提供了重要参考依据。In this paper,the studied region is located in the northeast of Sichuan Mt. Qinba, by the data from practical investigations and Forest Management Inventory （FMI） , colorful leaf forest landscape in Mt. Guangwu can be divided into 13 types and quantitative analysis is made by using ArcGIS technology and the landscape analysis program FRAGSTATS. The results have shown that the whole colorful leaf forest landscape has basic stability, abundance degree and aggregation. In all types of colorful leaf forest land- scape,the Betulaceae has the largest area, and the degree of its fragmentation is the lowest, followed by the Fagus and the Oakery. And yet many small areas of walnut, magnolia officinalis and so on display the highest degree of fragmentation. The difference in indexes of other types is not significant, and the degree of fragmentation of these types is in the medium range. These results could provide a significant basis for exploitation, utilization and management of colorful leaf landscape forest resources in Mr. Guangwu.
