摘要：

Information related to spatial distribution and dominants of soil organic matter (SOM) is critical for evaluating soil quality and assessing the carbon sequestration capacity, which play essential role in soil management and climate change mitigation. Until now, no reported research has conducted an extensive survey to predict SOM content, analysed SOM spatial variability, and determined the main controls of SOM variation in areas around Dongting Lake in southern China. Therefore, this study aims to (1) explore the spatial variability of SOM co...
