| Abstract: | On the basis of profound investigation of China's agricultual environment quality status carried in 1988 and heavy metal pollution data in part of commodity grain production bases of China ,the differences of heavy metal pollution in various maket grain production bases are analyzed and classified with multivariate analysis statistics. Fuzzy comprehensive evaluation method is applied to evaluate the extent of heavy metal pollution in different market grain bases. Therefore, the relative order of heavy metal pollution is obtained- |
