Main technical content: This document specifies the general principles, procedures, contents, and technical requirements for remote sensing analysis and investigation of soil ecological environmental damage at sites. This document is applicable to remote sensing analysis and investigation work involving soil ecological environmental damage caused by environmental pollution at sites. Soil ecological environmental damage can be divided into heavy metal pollution and organic pollution; according to different types of pollution and on-site conditions, the risk level of pollution is determined. The remote sensing analysis and investigation in this document solves the problem that the current soil pollution detection and analysis mainly rely on traditional indoor chemical analysis techniques, which are not only more complicated and time-consuming, but also cannot achieve real-time monitoring and it is difficult to obtain large-area continuous pollution information. The use of remote sensing technology can quickly and macroscopically understand the "spatial-temporal evolution" of soil pollution. This document includes the main text, 1 normative appendix (Appendix A), and 3 informative appendices (Appendices B, C, and D). Among them, the main text is divided into five chapters, namely the scope of application of this document, normative referenced documents, terms and definitions, workflow and work content, and report preparation. The normative appendix A is the soil condition record form, the informative appendix B is common hyperspectral satellite data, the informative appendix C is the land use classification system, and the informative appendix D is the outline for preparing the investigation report.
