| Abstract: | 53 soil samples were collected from yam planted area in Huilou and its periphery. Heavy metals＇ contents such as Pb, Zn, Cu, Cr, Cd, Ni in each sample were determined. Based on the classification and evaluation of the single factor deciding index, according to the importance of each single factor, added together the function of each single factor to establish the Fuzzy probability method model to evaluated the comprehensive pollutionof of soil heavy metals. The results indicated that the Huilou yam planted area was polluted heavily, but it was better than the surrounding areas, and the main pollution index was Cd. |
