| 摘要: |
| 根据青海湖流域土壤类型图采集了49 个表土样品，研究了这些样品的有机碳和黑碳的
含量特征及其储量。研究得出：六类土壤的有机碳含量都比较高，说明青海湖流域土壤的储碳能
力比较强；总体来说，六类土壤的黑碳含量都不高，但是焦炭的含量是相当高的，而烟炱的含量
较低；焦炭和黑碳的相关性极高，说明焦炭是黑碳的主要组成部分，并且说明二者具有相同的来
源；由于焦炭主要是由生物质燃烧生成的，故而这六类土壤的黑碳也多是由生物质燃烧生成的；
六类土壤总面积为18416.15 km2 （占流域土壤总面积的78%），有机碳总储量为119.56×106 t，
黑碳总储量为4.36×106 t。 |

| Abstract: |
| According to the map of soil type of Qinghai Lake basin, 49 topsoil samples were collected
to study the organic carbon and black carbon concentrations and reserves. Research obtained: organic
carbon content was higher in six types of soil, which indicated that the carbon storage of the soil of
Qinghai Lake basin was stronger; Overall, black carbon content was not high, but the content of charcoal
was very high , and lower levels of soot; there was a high correlation between charcoal and black carbon,
indicating that charcoal was the major component of black carbon, and that both had the same source; the
charcoal was mainly produced from biomass burning. And therefore, these soil black carbon were mostly
generated from biomass burning; the total area of these six types of soil was 18416.15 km2 (accounting
for 78% of the total soil area of Qinghai Lake basin), and its organic carbon storage was 119.56 × 106 t,
black carbon storage was 4.36 × 106 t. |
