Effects of herbage species on the spatial heterogeneity of biomass in grazed pasture: Kentucky bluegrass vs . White clover

摘要：

Recently, the spatial heterogeneity of plant biomass in grassland has been investigated from various approaches.However, those previous studies did not address the following aspect :.if different plant species are grown in grassland, will the dynamics of spatial heterogeneity of the biomass differ ?.This problem is important in evaluating the universality of the results of previous researches concerning the spatial heterogeneity of plant biomass.We investigated whether the different herbage species, for example Kentucky bluegrass ( Poa p ratensis L., KB) and white clover ( T ri f olium repens L., WC), influence the spatial heterogeneity of the biomass in grazed pasture.
