摘　　要：重金属污染土壤的生物修复技术是土壤污染整治的重要手段之一,是近几年来国内外研究的热点,同时也是现今土壤污染治理中环境友好、成本低廉的技术。本文主要论述了重金属污染土壤的植物-微生物联合修复的原理与形式,介绍了此技术中土壤重金属污染物特性、植物本身生理生化特性及植物根际环境等影响因素的研究进展,并讨论了植物-微生物联合修复今后的研究重点。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.
