We use fractal dimension(D),modified fractal dimension(Dm),landscape diversity index(H)to analyze the spatial pattern in relation to ecological processes of sandy landscapes in Kerqin,Inner Mongolia.Our results show that among three types of sandy landscapes,the artificial fixed sanddune region exhibited the most complex spatial pattern(Dm=15476),the fenced sanddune area was less complex(Dm=14975),and the flowing sanddune region was least complex(Dm=14205).This suggests that during des...
