【 摘 要 】

This paper focuses on the XiChaZhai village's vegetable soil which is located in the northern suburbs of Xi'an and on its vegetables, thus analyzes the quality of sewage irrigation region soil and its influence on vegetables through the measurement of Cu, Zn, Pb, Cd's content in samples. The results show that the research area soil contains apparently excessive heavy metals, and there exists significant differences of different elements' integrated intensity in soil, the content declines in sequence from Cd, Zn, Pb to Cu. The four heavy metals' contents in sewage irrigation region soil vary greatly from that in non-sewage irrigation region soil(P
