RF regression model data

Measured soil and mapped environmental variables to be used in a Random Forest model. d13C and d15N were also measured, and will be published seperately. Until then, d13C and d15N data are available upon request.Random Forest regression model used to understand relationship between subsoil OC and soil and environmental covariates to elucidate the controls on subsoil OC formation under perennial pasture grazing in Northern NSW, Australia.

本数据集包含用于随机森林（Random Forest）模型的实测土壤数据与经空间制图生成的环境变量数据。本研究同时测定了碳稳定同位素比值d13C与氮稳定同位素比值d15N，相关数据将另行发表。在此之前，d13C与d15N数据可应研究者要求提供。本研究采用随机森林回归模型，旨在解析澳大利亚新南威尔士州（New South Wales, NSW）北部多年生牧场放牧制度下，亚表层土壤有机碳与土壤及环境协变量之间的关联，进而阐明亚表层土壤有机碳形成的调控机制。
