摘要
本文测定了成都市街道地表物中的有机碳含量,并利用 W 法检验其分布类型。结果表明,有机碳含量为正态分布;地表物粒径增大有机碳含量减小;4种土地利用类型区地表物中有机碳含量是交通区>工业区,商业区>居民生活区.
The Content of organic carbon in surface dust in streets of Chengdu wasmeasured and its distribution type was tested by means of Shapiro-Wilk method.The re-sults show that 1) the content of organic carbon takes on normal distribution,2)the bigg-er the particle diameter,the lower the content of organic carbon,and 3) the content oforganic carbon in surface dust of four landuse type areas are traffic areaindustrial area,commercial arearesldential area.
