Abstract In order to enrich the information and broaden the research field of the geochemical evaluation,the authors carried out multi-purpose regional geochemical survey (MPRGS)by using the remote sensing (RS) technology based on the regular geochemical survey. The authors compared the advantages between the RS technology and the traditional geochemical investigation methods in such aspects as sampling point arrangement,sample acquisition and quality evaluation. The theoretical basis of the RS application in geochemical evaluation was discussed. With several examples,the technical procedures of the RS application in MPRGS work were summarized,which was a useful attempt to enrich the means of the MPRGS work. The application results of the RS technology in the MPRGS work show that using the RS technology in geochemical survey can help us expand the field of the RS application research and widen the field of geochemical research,and therefore the RS technology will surely become an important tool for the MPRGS work in the future.
