Patch dynamics and scale transition analysis of grassland in restoration succession
恢复演替中草地斑块动态及尺度转换分析

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 behind patch boundary shape.Fractal dimension of patch boundary has no scale transition at all scale in this study and patch size distribution shows scale transition which indicates different fractal characteristics at different scales.
