土壤有机碳作为陆地生态系统中的一个区域化随机变量,在系统内部垂直和水平发生变化的同时与大气圈和生物圈这两个碳库之间产生循环作用。为了揭示土壤有机碳的空间分布特性,传统统计学、地统计学、遥感与地理信息系统等方法被相继引入且逐渐走向成熟,其中利用遥感与地理信息系统相结合的方法来反演土壤有机碳库储量及其空间分布格局受到了越来越多的专家学者所推崇。本文在对不同方法基本理论进行简单阐述的基础上,介绍了它们在土壤有机碳的空间分布格局的研究中所取得的一些成果,并就遥感技术在反演表层土壤有机碳的空间分布格局中的应用前景进行了展望。
Soil organic carbon, as a regional random variable in terrestrial ecosystems, circulates between the two carbon pools, the atmosphere and the biosphere, both vertically and horizontally within the system. In order to reveal the spatial distribution characteristics of soil organic carbon, traditional statistics, geostatistics, remote sensing and geographic information system were introduced one after another and gradually matured, using the combination of remote sensing and geographic information system to retrieve soil organic carbon The reserves of reservoirs and their spatial distribution patterns are favored by more and more experts and scholars. Based on the brief introduction of the basic theories of different methods, this paper introduces some achievements they made in the study of the spatial distribution pattern of soil organic carbon. In the light of the spatial distribution pattern of soil organic carbon in the topsoil by remote sensing, The prospect of application is prospected.
