摘要(Abstract)：

基于辽河源2012年7月分辨率为10 m的遥感影像图及1∶5万的地形图、森林资源二类清查数据和GPS地面真实采集点,在地理信息系统软件ArcGIS、ENVI和景观指数分析软件Fragstats支持下,利用主成分分析方法降维选取对破碎化贡献最大的斑块形态指标,分析了冀北辽河源森林景观格局特征和破碎化程度。结果表明,各景观组分中阔叶林、油松面积最大,是辽河源地带性植被,分布集中,破碎化较小;华北落叶松、疏林地、居民地、道路和未成林地面积小,呈零散分布,破碎化程度较高,人为干扰程度大。各景观类型的平均分维数均接近1。景观整体破碎化水平较低,景观多样性指数为2.068 6,说明景观多样性丰富,异质性高;均匀度指数为0.783 8,说明景观类型分布均匀。各景观类型的边界褶皱程度均较低,整个景观的边界形状较为简单。

关键词(KeyWords)： 生态学;森林景观格局;景观指数;破碎化
