摘要
石油烃的污染是黄土高原地表覆盖区土壤污染的一个重要种类。对某土壤层中烃类污染物纵、横向进行了检测分析,对其烃类污染物晕染场的污染程度运用地质统计学进行了变差函数计算。研究工作依托Voxler平台可视化技术,对采样污染物数据进行了三维可视化的描述表征。充分利用场地中不同深度的样品数据,定量化的研究了有机烃类污染体在不同浓度条件下的空间染布形态,建立了三维晕染模型;通过多层次、多角度剖切以及三维污染晕染分析,探索了有机烃类污染在地表土壤空间中的散播方式,为三维可视化技术(voxler为例)在污染物扩散建模中的应用进行了有益的探索。该方法区别于传统污染治理多采用平面二维图对污染情况表征,直观的三维可视化展现污染物晕染体的空间形态,为下一步的污染治理分析指明了方向。
Pollution of petroleum hydrocarbons is an important type of soil pollution in the Loess Plateau.In this paper,the vertical and horizontal hydrocarbon pollutants in a soil layer are detected and analyzed,and the variation function of the pollution degree of the pollution field of hydrocarbon pollutants is calculated by using geo-statistics.Based on the Voxler platform visualization technology,the sampled pollutant data were described and characterized by 3D visualization.By making full use of the sample data of different depths in the site,the spatial dyeing morphology of organic hydrocarbon pollutants under different concentrations was quantitatively studied,and a three-dimensional staining model was established.Through multi-level,multi-angle cutting and three-dimensional pollution staining analysis,the diffusion mode of organic hydrocarbon pollution in the surface soil space was explored,which made a beneficial exploration for the application of three-dimensional visualization technology(Voxler as an example)in the modeling of pollutant diffusion.This method is different from the traditional pollution treatment,which mainly uses two-dimensional map to represent the pollution situation,and visually displays the spatial form of pollutants in three-dimensional visualization,which points out the direction for the next analysis of pollution treatment.
