青海湖流域六类土壤表土有机碳黑碳含量特征及其储量

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。

The characteristic of organic carbon and black carbon content and its storage in six types topsoil of Qinghai Lake basin of China

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.
