摘　　要：To grasp the characteristics of Pb, Cd, Cu and Zn in mulberry garden soil in Longchuan County, Yunnan Province, the single-factor pollution index method and multi-factor pollution index method were used to analyze the environmental quality of mulberry garden soil. The results showed that the Zn content in mulberry soils did not exceed normal water based on the soil pollution risk control standards for agricultural land, but the Cd content was high. The single factor pollution index of Pb and Cu did not exceed 2, and the exceedance rate of points was 16% and 24% respectively, while the single factor pollution index of Cd exceeded 3. The pollution of heavy metal Cd existed in the soil of mulberry garden. The average Pi values of soil heavy metals were ranked as Cd > Cu > Zn > Pb. Heavy metal combined pollution index of 6.58, pollution level of heavy pollution. Principal component analysis (PCA) of the four heavy metals showed that the two elements, Pb and Cu, were strongly correlated in their spatial distribution. Longchuan County mulberry soil heavy metal environmental quality evaluation, for the safe use of soil to provide a scientific reference basis.To grasp the characteristics of Pb, Cd, Cu and Zn in mulberry garden soil in Longchuan County, Yunnan Province, the single-factor pollution index method and multi-factor pollution index method were used to analyze the environmental quality of mulberry garden soil.
