区域土壤污染场地布点与监测方法研究

Site Distribution and Monitoring Method of Regional Soil Pollution

为了提升土壤污染场地布点和监测结果的准确性,提出一种区域土壤污染场地布点与监测方法。对区域环境数据进行采集,提取区域土壤内的梯度分布情况,将梯度系数的取值范围设定为控制目标,分别对区域土壤进行不同层次的场地进行布点。对土壤中污染物的扩散情况进行分析,构建污染物运移扩散的微分方程,计算污染度的浓度值,将浓度数据转换为电阻率数据,形成电阻率分布模型,根据正演计算获取区域土壤污染场地的监测数据。经实验测试证明,所提方法可以更好完成区域土壤污染场地布点与监测。

In order to improve the accuracy of soil pollution site distribution and monitoring results, a regional soil pollution site distribution and monitoring method was proposed. The paper collected the regional environmental data, extracted the gradient distribution in the regional soil, set the value range of the gradient coefficient as the control target, and arranged sites at different levels of the regional soil. It analyzed the diffusion of pollutants in soil, built the differential equation of pollutant migration and diffusion, and calculated the concentration value of pollution degree. The concentration data was converted into resistivity data to form the resistivity distribution model, and obtain the monitoring data of regional soil pollution sites according to forward calculation. The experimental results show that the proposed method can better complete the site distribution and monitoring of regional soil pollution.
