Abstract: Bioremediation is one of the important means in controlling soil heavy metals pollution, which has the advantages of environmentally friendly and cost-effective, and attracted much attention around the world. This paper discussed the principles and forms of plant-microorganism combined remediation, and introduced the research progress on the behaviors of heavy metals in soils, the physiological and biochemical characteristics of plants, and the changes in rhizosphere environment under the remediation. Some perspectives for future research were proposed.
