摘  要：
以上海城市绿地土壤为研究对象,通过对不同土地利用方式下绿地土壤黑碳和有机碳的分布特征进行分析,结果表明:上海市绿地土壤黑碳含量范围为0.29~86.07 g kg-1,最大值出现在钢铁厂,平均值为11.13 g kg-1。土壤中黑碳与有机碳、BC/OC值的相关极显著。土地利用方式不同,绿地土壤的黑碳含量也不一样;研究区内绿地土壤BC/OC的平均值为0.42,其中公园学校土壤黑碳含量和BC/OC值最低。不同土地利用方式对绿地土壤黑碳来源影响不同,钢铁厂、造船厂、机械制造和试剂溶剂厂的土壤黑碳来源为工业排放和石油、煤炭等燃料燃烧;居民办公区和公园学校,土壤黑碳来源为木炭、煤渣的排放,绿化植物枯枝落叶的人为燃烧;交通区土壤黑碳来源比较单一,主要为汽车尾气排放所致。

摘  要：
The distribution characteristics of black carbon and organic carbon were studied in different land-use patterns of greenbelt soils in Shanghai. The content of black carbon ranged from 0.29 g kg-1to 86.07 g kg-1in greenbelt soils of Shanghai, the highest value of which occurred in iron-steel factories, with a mean of 11.13g kg-1. There was a highly significant correlation between black carbon and organic carbon or BC/OC. The content of black carbon was different in land-use patterns of greenbelt soils. Meanwhile, the contents of black carbon and BC/OC were the lowest in parks and school, with a mean BC/OC of 0.42. The sources of black carbon were different in different land-use patterns of greenbelt soils Sources of soil black carbon of iron-steel factories, shipyards, mechanical and chemical-reagent factories were oil, coal and other fuel combustion and industrial emission, while those of residential and office areas, parks and school were charcoal, coal cinder emission, greening plant litter combustion. However, the sources of black carbon in traffic areas were single, mainly deriving from the motor vehicle emission.
