摘    要:选取4个斑块形状指数(斑块的击长面积比SI1、斑块周长与等面积的圆周长之比SI2和身份个斑块分维SI3和SI4)并借助GIS软件ARC/INFO对北京地区植被景观中的斑块形状进行分析,又地这四个形状指数进行 earson相关分析和Spearman秋相关分析,结果表明,SI1与SI4,SI2与SI3两两之间均呈显著的正的秩相关,SI1与SI2,SI2与SI4,SI3与SI4两两之间于垢负和秩相关。因

Abstract: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 ...
Keywords:vegetation landscape  patch shape  shape index  correlation analysis  geographical information system(GIS)
