In order to standardize the projects of agricultural geology survey, CGS organized and drew up three norms. The first one is standards for multi-objective regional geochemistry survey (1:250000) . The second one is technical requirements of the regional ecological geochemistry evaluation (for trail). The last one is technical requirements of the analysis on ecological geochemistry sample (for trail)

　　Recently, these three norms will be published on the web site of China Geological Survey .
