Abstract:Through multi-target geochemical survey advances have been made in the study of the back-ground values and distribution characteristics of the elements,study of structure,agriculture and environ-mental pollution,prediction of natural gas and calculation of the pH values.It is judged that the deep-lay-er samples play a special role in the study of the distribution of deep-seated elements,structure,develop-ment of root-deep crops and prediction of natural gas and that the shallow-layer samples plays a special role in the study of the distribution of shallow -seated elements,agricultural geology and environmental pollution.The multi-target geochemical survey and double-layer sampling can be popularized.
Keywords:multi-target geochemical survey  element  background  structure geochemistry  agricultural ge-ology  pH study  environmental pollution  prediction of  natural gas
