基于SBAS-InSAR的地表形变监测技术在化工园区地下水污染精准溯源中的应用研究
Research on the Application of SBAS-InSAR-based Surface Deformation Monitoring Technology for Precise Trac-ing of Groundwater Pollution Sources in Chemical Industrial Parks
摘要
Abstract
Groundwater pollution in chemical industrial parks remains a serious environmental concern.Precise tracing of groundwater pollution sources is essential for achieving accurate,scientific and law-based pollution control,as well as safeguarding public health and ecological security.In this study,the small baseline subset interferometric synthetic aper-ture radar(SBAS-InSAR)technique was applied to monitor surface deformation in a chemical industrial park from 2017 to 2025.By integrating remote sensing data(surface deformation)and on-site investigation data(groundwater pollution sur-vey results and anti-seepage investigation results by multi-methods),this study finds that:(1)The overall surface was stable,but localized subsidence ranges from-25 to 14 mm·a-1,with a maximum cumulative value of approximately 190 mm during the monitoring period,mainly caused by industrial production and waste landfilling.(2)Compared with non-subsidence zones and uniform subsidence zones,areas characterized by uneven subsidence exhibited higher exceedance rates(91.07%)of groundwater contaminants,with the severe exceedance rate reaching 25.00%.Moreover,the groundw-ater sampling sites within enterprises exhibited excessive pollutants with industrial production waste water,such as Al,Ni and extractable petroleum hydrocarbons(EPH),which indicates that leakage from damaged underground facilities is a major contributor to groundwater contamination.(3)Multiple cases of pipeline damage,deformation,and pond leakage were identified at uneven subsidence sites of typical enterprises monitored by SBAS-InSAR.This study suggests that sur-face deformation monitoring is valuable for identifying potential risks of underground infrastructure failure and is recommen-ded as a pre-screening tool for precise groundwater pollution source tracing.The results of this study can provide guidance for the prevention and control of soil and groundwater pollution of chemical industrial parks.关键词
