| Abstract: | In order to inquire into the environmental quality of commodity grain bases of China,the paper selects five heavy metal pollution data in some commodity grain base counties of China to build up analysis model and obtain the difference map of heavy metal in 77 commodity grain base counties,for analysis of the pollution difference; meanwhile, establishes the Fuzzy comprehensive evaluation method to evaluate the extent of heavy metal pollution in different grain bases and obtain the relative order of heavy metal pollution. |
