YANG Zhong-fang, CHEN Yue-long, WANG Ming-qi,XI Xiao-huan, XIAO Gui-yi, et al. THE STATUS OF INTERNATIONAL GEOCHEMICAL MAPPING AND SUGGESTIONS TO CHINA'S MAPPING[J]. Advances in Earth Science, 2002, 17(6): 826-832.

Synthetic regional geochemical investigation has been carried out in many counties at the goals of environmental investigation, mineral resource exploration, land reasonable using and green agriculture. The exploration geochemical circles of Russia and China have conducted geochemical mapping of multi-purpose. And other developed and developing countries have also conducted regional geochemical investigation and related research in order to solve their own environmental problems. Studying aspects are as following:①Regulation land reasonable using and regional development programming. Through study of distribution and partitioning laws on beneficial and harmful elements in soil to animals and plants, the proposals are provided for reasonable land using and development programming of studied regions considering characters of geography, geomorphology and landscape.②The investigation of environmental pollution degrees and background values, which involves in the comparison of environmental key factors before and after exploitation of mines, the investigation of environmental background values in soil and water, and evaluation of regional ecological environmental quality.③Forecasting mineralization potentialities of a region; after synthesized processing of anomaly diagrams for mineralization and concomitant elements in different sampling media, composite geochemical anomaly maps may be used for prospecting of mineralization potentiality.④Original geochemical investigation for the purpose of prevention and curing on local endemic diseases and health of animals and plants.⑤The estimation of land fertilization to serve reasonable topdressing and green agricultur through systematic investigation of distribution laws on effective part and contents of major and minor elements in plants. The authors present some suggestions on multi-purpose geochemical mapping of China from now based on current international status.
