The differences of the contents of heavy metals are obvious in the different vegetable kinds and breeds. The vegetable breeds which average contents of heavy metal are high have three-coloured amaranth, asparagus lettuce, raw vegetable, onion; which variable coefficient of heavy metals are big have cabbage, hot pepper, onion. The contents of many heavy metals in leaf vegetable are bigger than in fruit and vegetable. The correlation analysis in the different vegetable kinds shows that the correlation degree is bigger in leaf vegetable than in fruit and vegetable. The correlation analysis of heavy metals displays the correlation degree of the different vegetable breeds is bigger in asparagus lettuce than in cabbage than in kidney bean than in onion than in hot pepper than in raw vegetable than in three-coloured amaranth. The classify analysis of heavy metals shows that the coordination and formal of heavy metals are large differences in the different vegetable breeds, and the contents of heavy metals of same vegetable breeds have similarity. We find that the main vegetable breeds that beyond standards are leaf vegetable, and the areas that beyond standards main are in the outskirts of a town, and the main heavy metals that beyond standards are Pb Cd.
