Analysis of the patch shape with shape indices for the vegetation landscape in Beijing
北京地区植被景观中斑块形状的指数分析

Four patch shape indices,which include ratio of perimeter to inner area of a patch( SI 1),ratio of patch perimeter to the perimeter of a circle with equal area with the patch( SI2 ),and two fractal dimensions of a patch( SI3 and SI4 ),were chosen to analyse the shape of patches in the vegetation landscape in Beijing using GIS software,ARC/INFO.The correlations among the four indices were analysed with Pearson correlation coefficient and Spearman rank correlation coefficient.The results show that ...
