渭河流域河水硝酸盐氧同位素以及水化学指标数据集
A dataset of nitrate oxygen isotopes and water chemical indicators in the Weihe River Basin
摘要
Abstract
The combined application of nitrate oxygen isotopes and water chemistry indicators is a key technical approach for analyzing the sources of nitrate pollution in rivers and the processes of its migration and transformation.This technical combination can effectively trace the formation mechanisms,migration pathways,and biogeochemical transformation processes of nitrate,providing isotope geochemical evidence for"total nitrogen control"at the watershed scale.It holds significant scientific value in water resource management,watershed ecological protection,and nitrogen cycle research under the backdrop of global climate change.This study focus on the Weihe River Basin,a typical basin in the arid-semi-arid region of western China,and systematically compiles nitrate oxygen isotope and water chemistry indicator datasets from the main stem and tributary rivers of the Weihe River Basin(including the main stem of the Weihe River and the Hei River,Ba River,Feng River,Liao River,Chan River,and Jing River)in the Wei River basin.The dataset is organized in Excel files,with separate files for each of the seven rivers.The data sources consist of two parts:one part is data measured by our laboratory,which has undergone rigorous experimental procedures and analytical methods for quality assurance and quality control;the other part is data cited from published research results in this region,all of which are based on data from published literature to ensure data reliability.This dataset provides fundamental data support for the spatiotemporal distribution and source tracing mechanisms of water pollutants in the Wei River basin,laying a theoretical foundation for effective pollution control in the future and providing a scientific basis for water resource management within the basin.关键词
