这篇论文验证了这样一种假设，即干旱地区有可能对全球碳固存做出显著贡献。这是一个项目的一部分，该项目的目标是通过植树造林将目前的碳固存水平提高5/20倍，采用有效的集水、灌溉、改良土壤的耕作、仔细的物种选择和开发增加降雨量的系统。在年平均降雨量为208 mm的西澳大利亚州列奥诺拉附近，对4个植物群落中选定的灌木和乔木进行破坏性采样，以测量叶、枝、茎和根对生物量的贡献。数据表明，该地区植物群落对总现存量的贡献范围为600 kg DM/ha~82t DM/ha，平均为8.5t DM/ha(4.1t-C/ha)，整个斯图尔特草甸站(299,250 ha)平均为8.5t DM/ha(4.1t-C/ha)。赤桉可固着16 kg-C/株/年和10tC/ha/年。
This paper tested the hypothesis that arid areas have the potential to make appreciable contributions to global carbon sequestration. This is part of a project which has the aim of increasing the present level of carbon sequestration by 5{approx}20 times by afforestation using systems such as efficient water harvesting, irrigation, soil-improving cultivations, careful species selection and development of systems to increase rainfall. Near Leonora in Western Australia, where mean annual rainfall is 208mm, selected shrub species, and tree species in four plant communities were destructively sampled to measure the contributions to biomass of leaves, branches, stems and roots. The data suggests that in this area plant communities contribute a range of 600kg DM/ha to 82t DM/ha of total standing biomass, with a mean of 8.5t DM/ha (4.1t-C/ha) over the entire Sturt Meadows Station (299,250ha). Eucalyptus camaldulensis could sequester 16kg-C/plant/y and 10tC/ha/y. (Author)
