Abstract
Large-scale forestation in arid areas is looked upon as one possibly countermeasure against global warming. Because it has never done, the methodology and the effect of the forestation are being considered in Leonora. Western Australia, where mean annual rainfall is approximately 200mm. An estimation of biomass in some ground-truth points and the application of remote sensing are essential to evaluate the effect of carbon sequestration by the forestation. Therefore in this study, the biomass was estimated in 13 representative plant communities in Leonora. The biomass of plants was estimated by destructive samples and complete enumeration in each site. Grass was weighed by Quadrat method. The conclusions were as follows. 1) In the destructive samples, dry weight of each component part was strongly correlated to projected foliage area, and the correlation was regular even in different species. Judging from these results, the biomass in the research area could be estimated by the application of remote sensing. 2) The biomass in the most sites was much heavier than in typical arid areas, and it was about 14kg/m^2 in an Eucalyptus forest, 6〜7kg/m^2 in dense Acacia forests and 0.5〜5kg/m^2 in sparse Acacia forests, respectively.
