Abstract
By analysis on various soil element concentration order under different pollution sources in the study are⁃a, is is concluded that:the order of heavy metal concentration in the soil profile is dumping pollution>sewage dis⁃posal pollution>livestock and poultry stool pollution;water-soluble salts like K+,Mg2+,Na+,Cl ,SO24 , affected by sewage pollution significantly, the concentration order in the soil is sewage disposal pollution>livestock and poultry stool pollution>dumping pollution. The concentration order of NO3 in the soil is livestock and poultry stool pollution>sewage disposal pollution>dumping pollution;the order of soil constant nutrient concentrations is sewage disposal pollution>dumping pollution>livestock and poultry stool pollution. On the view of elective cultivation, in the land that heavy metal is accumulated, but soil is fertility, the vegetables ( or fruits) that accumulate less heavy metal can be planted. On one hand, the advantage of soil fertility can be realized;while on the other hand, it is better avoid⁃ance of heavy metal pollution on crops.关键词
