Patch boundary shape and patch size distribution in 9 year restoration succession was studied scale transition points were determined using fractal method.Both fractal dimension of patch boundary and patchiness exponent of Aeluropus littoralis were the highest,and that of Aneurolepidium chinense were lower.Patchiness exponent of Suaeda glauca was a little lower than that of Aneurolepidium chinense and fractal dimension of patch boundary was higher.Dynamics of patch size distribution lag be...
