污染场地环境调查与风险评估中的软件应用

The Software Application During Contaminated Site Investigation and Risk Assessment

污染场地环境调查评估作为场地治理修复的前期工作,其结果的准确性对后续场地修复和规划利用起着决定性的作用。调查评估结果依赖监测点位的可靠性、现场采样的规范性、实验室检测结果的准确性来获取正确的调查数据,后续需要运用多种模拟软件对调查数据进行运算,模拟出调查评估场地内土壤及地下水的污染趋势。本文介绍了场地环境调查评估领域用到的Surfer、ArcMap和Voxler三种模拟软件,其中Surfer软件和ArcMap软件主要用来绘制二维图形,Voxler软件用来绘制三维图形,阐述了三种软件的优缺点和适用性,为污染场地环境调查及风险评估提供参考。

Contaminated site investigation and risk assessment,as the preliminary work of site remediation,play a decisive role for the site restoration and reuse.The accuracy and reliability of investigation process,sincerely depends on the reliable position selection,correct survey data,normative sampling methods and precise testing procedures.During the assessment process,several software can be applied for the simulation of the pollution status of soil and groundwater,such as Surfer,ArcMap and Voxler,which all have been widely used in the process of pollution assessment.In this paper,each software was introduced along with the case study.Surfer and ArcMap are mainly known as the plane simulation,and two dimensional plotting can be exported for the vision of pollution distribution.Voxler considered the 3D graphs output,which is an intuitional instruction of the pollution status.The advantages,disadvantages and feasibilities of the three kinds of software are expounded to provide reference for environmental investigation and assessment of contaminated sites.
