摘要
本文对白洋淀沉积物中黑碳和有机碳含量进行了特征分析.研究发现,沉积物中黑碳与有机碳的质量分数具有一定的正向线性相关性,并且黑碳和有机碳质量分数的比值随着黑碳质量分数的增加而增大,白洋淀地区黑碳含量相对较低,主要来源为生物质燃料燃烧和汽车尾气排放.
Abstract
This article analyzes the characteristics of black carbon and organic carbon content in the sediment of Baiyangdian Lake.Research has found that there is a certain positive linear correlation between the content of black carbon and organic carbon in sediments,and the ratio of black carbon to organic carbon content increases with the increase of black carbon content.The black carbon content in the Baiyangdian area is relatively low,mainly from biomass fuel combustion and vehicle exhaust emissions.
