| 摘 要： | 根据实地采样数据,运用地统计学方法分析苯并(a)芘污染的空间变异特征,同时研究各地污染水平与其自然环境、产业布局之间的关系。结果表明:土壤苯并(a)芘含量在研究区存在空间异质性,在240 km空间尺度上尤其明显,块金值(C0)和基台值(C0 C)之比为44%;这说明其空间变异由结构性因子(如土壤有机质)和随机性因子(如污染源分布)共同构成;钢铁工业(包括焦化工)是苯并(a)芘的主要排放源,土壤苯并(a)芘污染也以钢铁工业(包括焦化工)发达的城市及其附近区域为核心。 |

| Abstract: | Based on data collected in the field survey,spatial variation of benzoa]pyrene in soil was studied by means of geostatistical analyst with ArcGIS,and relationships of its contamination level with the natural environment and industry distribution of the region were analyzed.Results indicate that spatial heterogeneity of benzoa]pyrene concentration exists in the soil of the study area,and is especially distinct at the spatial scale of 240 km,with nugget/sill ratio C_0/(C_0 C) being 44%,suggesting that the spatial variation is made up of structural factors(e.g.soil organic matter) and random factors(e.g.distribution of pollution sources).The steel industry,including coking plant,is the main emission sources of(benzoa])pyrene,and benzoa]pyrene contaminated soils are distributed around the steel industry developed cities and their vicinities. |
