近年来，土壤重金属污染问题日益严重，已从传统的单一重金属元素污染转变为重金属的复合污染。从土壤重金属复合污染对土壤中重金属元素的迁移转化、土壤微生物群落结构、土壤酶活性以及植物生理的影响等方面阐述了其生态效应，并对存在的问题和发展前景提出见解。

In recent years， rapid development of industry and agriculture modern technology to the growing problem of heavy metal pollution of soil， from the traditional heavy metal pollution into a single composite heavy metal pollution. This heavy metals from the soil pollution on the migration of heavy metals in soil， soil microorganisms， soil enzyme activity and plant physiological role into the impact of four described their ecological effects， and the problems and prospects for development put forward their own views.
