Abstract This paper deals in detail with the regional geochemical environment of Gejiu area in Yunnan Province on the basis of
regional geochemical data combined with achievements obtained in such aspects as medical geology, agricultural geology and
environmental geology. Fuzzy comprehensive assessment (FCA) was used to evaluate the regional geochemical environment over 630
km2 of Gejiu area. It is concluded that the regional geochemical environment of Gejiu area has been polluted severely, resulting
not only from the disadvantageous natural environment but also from the pollution of local factories. The situation deserves
serious attention.
