Multi-scale effects of spatial correlation for vegetative landscape types in the Wuyishan Nature Reserve

摘要: 利用二元列联表和方差比率法,对福建省武夷山自然保护区植被景观斑块的空间关联性的多尺度效应进行了研究。结果表明:景观要素类型间的空间关联性的强弱是随着取样空间尺度变化而有所变化,不同的要素类型间关联性随空间尺度的变化的幅度也有所不同,对于该区域应在600m600m空间尺度上研究较为合理;景观斑块的全局关联性在一级分类标准下是负相关,但在二级分类和三级分类标准下,呈现正相关性。表3参13Abstract: Using a binary contingency table,a variance ratio test,and a correlation analysis,multi-scale effects of spatial correlation for vegetative landscape types in the Wuyishan Nature Reserve were studied. Results showed that the spatial correlation intensity for landscape types changed as the spatial scale changed,with the spatial correlation of different landscape types changing to different extents. The best scale to study this area was a 600 m600 m spatial scale using landscape patch types. The overall association of landscape patch types showed a negative correlation for the first class,but a positive correlation for the second and third classes[Ch,3 tab. 13 ref.]
