| 摘 要： | 分析了沿青海湖湖岸采集的81个表土样品的总有机碳和氮含量得出：环湖区表土有机碳储量为27.81×10^6t,总氮储量为30.24×10^5t。占研究区面积最大的栗钙土,其表层土壤有机碳密度（8.19kg/m^2）显著高于同类研究,氮含量（3.63mg/g）亦高于青海省同类土壤的平均值,说明环湖区表土碳氮储量都是相当大的...

| Abstract: | Analysis of TOC and nitrogen of 81 topsoil samples around Lake Qinghai shows: TOC storage is 27.81×106t,TN storage is 30.24×105t.Chestnut soil is the largest soil type in the research area,and its organic carbon density(8.19kg/m2) is significantly higher than similar studies,its nitrogen content(3.63mg/g) is also higher than the same soil in Qinghai Province,on average.This indicates that the storage of organic carbon and nitrogen in topsoil around lake Qinghai are considerable.Meanwhile,the storage of organic carbon and nitrogen in topsoil shows linear correlation. |
