Abstract
重金属污染是目前全国各地较为突出污染现象，主要表现为土壤和水的污染，由于工业的发展，加上废水废气处理不当，导致这个现象愈发严重，如何治理也成为了迫在眉睫的问题。本试验主要通过给土壤加入适当的镉、锌含量，小型模拟污染土壤，通过对九层塔、柠檬薄荷、迷迭香、柠檬香草4种植物的种植，对形态指标、生物量、植株重金属含量和土壤重金属含量进行测定，同时引入转运系数和富集系数，对比得出对土壤修复更有潜力的植物。 Heavy metal pollution is the typical polluting objects the of country pollution phenomenon. It mainly performed for soil and water pollution. Due to the industrial development and wastewater and exhaust gas is improperly treated, that cause the phenomenon is more serious. How to manage it has becomes an imminent problem. This test added appropriate cadmium, zinc in the soil and plant basil and lemon mint and rosemary and lemon vanilla in the soil .And then we measured the morphological index, biomass, plant heavy metal content and soil heavy metal content. And we lead into transport coefficient and enrichment coefficient to compare four plants that which have more potential for soil remediation.
