摘　　要：从生物修复的概念和重金属污染土壤的方式出发,对重金属污染土壤植物修复和微生物修复两个方面的一般原理、方法和研究动态进行了综述,指出:重金属污染土壤生物修复基本上处于试验开发阶段,其今后研究的重点为探索超积累植物修复的机理,开发土壤改良剂和生物吸附剂以增加效益,超积累植物生物学性状的改善和微生物基因工程菌的构建,以生物修复为核心的联合修复作用的发挥及生物修复指标体系的建立。可以预料,重金属污染土壤生物修复具有很大的发展前景。The technology of bioremediation becomes a new area of research with features of low cost, high efficiency, no second pollution and wide applicability. This paper, based on the conception of bioremediation and the situation of soils contaminated by heavy metals, reviews the general principles ,methods and the researches related with phytoremediation and microbial remediation for soils contaminated by heavy metals. It is shown that the researches are still at the test development stage, with focuses on hyperaccumlators remediation mechanisms, soil conditioners and bio adsorbents, improvement of biological properties of hyperaccumlators, construction of micro-organisms with genetically engineered bacteria, joint remediation based on generalized remediation as its core technology, and indicator systems. It is anticipated that bioremediation will make great progress in near future.
