Abstract:Spatial patterns of the above-ground biomass were determined using a geostatistical analysis in the degraded grasslands in Ordos. The results show that, with degradation of grasslands in Ordos, the heterogeneity in spatial distribution of the above-ground biomass and the distance (range) of spatial dependence varied significantly. Among the five communities concerned, Stipa bungeana community had the smallest value of sill (C 0C) (0.48), indicating that the distribution of the above-ground biomass was not ...
