Abstract:
This study aims to further tap the remote sensing monitoring technique in monitoring the current land use of brownfields, including risk control, soil remediation, and development and construction. Firstly, this study selected 98 brownfields of Zhejiang Province that have been included in the risk control and remediation list in the national contaminated soil information management system. Then, using images of the historical period and the monitoring period from the domestic high-resolution remote sensing satellite, this study conducted the remote sensing monitoring of changes in land use through image processing and human-computer interactive interpretation on the ArcGIS platform. Finally, this study made statistics of the monitoring results by combining the reports on the surveys, risk assessment, and control and remediation effects of the brownfields, as well as the attribute information of the brownfields. The results show that the monitoring based on the remote sensing technique can be used to quickly identify the implementation of risk control, soil remediation, and development and construction of the brownfields and timely grasp the current status, dynamic trends, and issues of the use of brownfields included in the risk control and rehabilitation list. This study will provide technical support and bases for relevant public departments to carry out the access management of the redevelopment of brownfields.
