Regulation of local water availability on carbon sequestration of forestation in northern China

This data is based on a large-scale paired field investigation conducted during 2012–2013 across the Three-North Shelterbelt region of northern China. We conducted a large-scale paired field investigation involving 613 control–forested plot pairs, encompassing measurements from 25,304 trees and 11,700 soil samples. Carbon stocks and sink in biomass, SOC, and SIC were quantified along a continuous aridity gradient, with analysis of direct and indirect effects of water availability, including its influence on tree species selection.

本数据集源自2012-2013年间在中国北方三北防护林（Three-North Shelterbelt）区域开展的大规模配对野外调查。本次调查共布设613处对照-造林样地配对组，完成了25304株林木的测定与11700份土壤样品的采集。研究沿连续干旱梯度，量化了生物量、土壤有机碳（SOC）与土壤无机碳（SIC）组分中的碳储量及碳汇能力，并解析了水分可获得性的直接与间接影响效应，包括其对林木物种选择的调控作用。
