摘要:
以完达山东部地区现实景观为背景，使用主成分分析方法对设置的多尺度景观格局破碎情景进行分析。结果表明，主成分分析在景观水平上能准确地表征完达山东部地区多尺度景观逐渐破碎的过程，在类水平上表现效果不理想。斑块数量、斑块密度、对比度加权边缘密度、总边缘长度、边缘密度、景观形状指数和总边缘对比度在1000 m以下尺度能很好地表征农田斑块变化过程，阔叶林斑块的格局指标在几组尺度上表现破碎过程规律一致，基质斑块格局指标对景观破碎的多尺度响应更复杂。
Abstract:
According to the real landscape of East Wanda Mountains, PCA was used to analyze the multiple scale landscape fragmentation pattern scenarios. The results showed that: PCA can expressed multiple scale landscape fragmentation process accurately in East Wanda Mountain in land scape level, but can’t in class level. Total number of patches, patch density, contrast weighted edge density, total edge length, edge density, landscape shape index and total edge contrast index can express farmland variation process under 1 000 m scale. Pattern metrics of broad-leaved forest had the same rule in expressing fragmentation process in several scale groups, and multiple response of matrix patch pattern metrics to landscape fragmentation was more complicated.
