| 摘 要： | 利用因子分析法及离散点曲面张力样条函数插值法对天津地区表层土壤多环芳烃类污染物污染源的类型及空间分布进行分析，表明研究区不同土地利用类型的污染源大多以混合源（包括燃煤与原油渗漏）为主，其中污灌农田、普通农田、荒地和城市绿地中混合源所占比重依次为61.26%、69.35%、52.86%、64.45%。而各污染源在空间分布上与其所处地理位置、地理条件及该区域内人们的生活习性都比较符合。 |

| Abstract: | Based on plant cover, history of wastewater irrigation, landscape status and other geographic entities, the sample sites were classified into farmland of wastewater irrigation, common farmland, wild land, oil field and city greenbelt. The uniform gridding scatter sampling method was adopted to collect 188 surface soil samples, which were exacted from varions matrixes, foilwed by some clean up procedures and then analyzed by GL/MS. Using the PAH data collected from surface soils of Tianjin, accordingto the factor analysis and scatter point surface tension spline function interpolation, some types and spatial distributions of pollution sources of PAHs of soil in Tianjin area were investigated and discussed in this paper. The result showed that most types of pollution source are mixed sources, including coal combustion and oil spill in surface soils of different types of soil utilization in Tianjin area. Mixed sources occupy 61.26%, 69.35%, 52.86% and 64.45% in farmland of wastewater irrigation, common farmland, wild land, and city greenbelt, respectively, and the spatial distributions of pollution sources are closely related with their geographic locations, geographic conditions and living habits of indigenes. |
