Abstract

Biomass is an important structural parameter for investigating for ecosystems dynamic, the level of biodiversity, carbon cycle and ecosystems sustainability. In addition, the quantification of biomass resources is required in many studies, such as the analysis of fixed-emission of CO2. This research focused on quantifying the influence of GRAZING INTENSITY on aboveground and BELOWGROUND BIOMASS on the arid shrublands that is covered byArtemisi sieberi. Intensity levels were quantified as non-grazing, moderate and heavy based on the rate of vegetation utilization. In all treatments, aboveground and belowground (0-25, 25-50, 50-75 cm) were sampled. To estimate aboveground and BELOWGROUND BIOMASS, their relationship and effect of GRAZING INTENSITY in biomass compartments, simple biomass equations were extended in each treatment. There were strong linear relationships between volume and ABOVEGROUND BIOMASS and also between aboveground and BELOWGROUND BIOMASS in all the treatments. These relationships and functions could be used in similar studies. Although the result showed aboveground and BELOWGROUND BIOMASS and their relationship can be affected by livestock grazing, the dimension of these changes was highly depended on GRAZING INTENSITY. Aboveground and BELOWGROUND BIOMASS was decreased significantly by grazing intensities in both heavily and moderately grazed sites in comparison with non-grazing treatment. It was seen that grazing not only had a potential to change the amount of aboveground and BELOWGROUND BIOMASS in ecosystem, but also could change the allocation of these elements and relative allocations of belowground that were increased by GRAZING INTENSITY. In our study, although HEAVY GRAZING reduced the amount of biomass, MODERATE GRAZING didnot respond to plant biomass in this area.
