摘要
应用地统计学技术对全天津地区表层土壤中 16种优控多环芳烃含量和土壤理化参数进行了空间结构分析 .结果显示 ,各组分浓度均存在中尺度的空间自相关性 .多环芳烃浓度的空间结构存在明显的各向异性 .大气运移和土壤TOC含量可能是影响土壤多环芳烃浓度空间结构特征的重要环境因素 .
By methods of geostatistics, 16 prior PAHs contents in the topsoil of Tianjin Area, as well as the soil properties, were studied. The medium scale spatial autocorrelations were well revealed. The spatial structures of PAHs contents demonstrate significant anisotropy. Transportation via atmosphere and content of soil TOC may be two major environmental factors that influence the spatial structures of PAHs contents in soil.
