我国污染场地修复决策系统研究进展

Progress of the research on the decision system of contaminated site restoration in China

自2016年《土壤污染防治行动计划》实施以来,随着污染土壤修复工作的推进,因场地污染类型、污染程度以及土地规划类型等因素的不同,如何筛选出科学、合理、高效、低耗的修复技术显得尤为重要。在此背景下场地修复决策系统应运而生,即通过输入修复过程所有要素并结合专家判断,修复决策系统运算得出最佳修复模式,为管理者提供决策依据。本文在分析国内外修复决策系统的发展现状、特点以及优势和劣势基础上,以焦化污染场地为例拟开发基于WebGIS的污染场地修复辅助决策系统,以找出适合我国污染场地修复决策的模式,为从事相关工作的研究者和决策者提供参考。

Since the launch ofthe Action Plan for Soil Pollution Prevention and Control in 2016,the remediation of contaminated soil was progressing steadily.However,there were great differences in the type,degree and land planning of site pollution.So it is particularly important to select the remediation technology which is scientific,reasonable,efficient,and low-consumption.In this context,the remediation decision supporting system came into being.By inputting all the elements of the remediation process and combining expert judgment,the remediation decision supporting system calculates the best remediation mode,and provides a basis for decision-making for managers.This paper analyzed the development of domestic and foreign remediation decision supporting system,compared its characteristics,advantages and disadvantages.Based on this,the paper found a model suitable for the remediation of contaminated sites in our country and provided references for researchers engaged in this work.
