| 摘 要： | 目前在估算土壤有机碳储量方面的方法较多,并且都有其各自的特点所在。地理信息系统(GIS)技术作为当今一种在地学统计分析方面具有强大空间分析功能的计算机应用技术,在地学及相关研究领域得到了广泛的应用。文章首次尝试了利用该技术估算柴达木盆地土壤有机碳储量,该方法与其它计算方法相比,有简单、易操作、可视性好等优点。经计算,柴达木盆地的土壤有机碳储量约为62754.442 t,土壤平均碳面密度为6.105 kgm-2。

| Abstract: | There are many methods of calculating the density and storage of organic carbon in soils both at home and abroad, but no one or institute does any research in this field by using the technology of geographic information systems, which is one of the statistics and analysis computer technologies with strong spatial analysis in the geoscience research. So in this paper, the idea of applying this technology to the research field is brought forward, how to make use of the technology is illustrated by managing it to calculate the storage of organic carbon in soils of Qaidam basin. According to the results of calculation, the storage and density of organic carbon are about 62754.442 t. and 6.105 kgm-2 respectively. |
