摘　　要：当前,土壤的重金属污染问题十分严峻,植物有效性作为评价土壤中重金属的迁移能力和生态环境风险的关键指标受到广泛关注。本文首要介绍了重金属植物有效性的概念,其次从土壤理化性质、重金属特性、植物种类三个方面详述了植物有效性的影响因素,再次审查概括了以物理化学法为主的植物有效性评价方法,最后对植物有效性的未来发展进行了展望。本文期望为今后植物有效性这一概念应用于重金属污染土壤的生态风险评价工作提供科学依据。At present,the problem of heavy metal pollution in the soil is severe,and phytoavailability has been widely concerned as a key indicator in evaluating the migration capacity and eco-environmental risk of heavy metals in soil.This review introduces the concept of phytoavailability of heavy metals,and details the factors affecting phytoavailability from three aspects:soil physicochemical properties,heavy metal properties,and plant species.The review outlines the phytoavailability evaluation methods based on physicochemical methods,and provides an outlook on the future development of phytoavailability.This work is aimed to provide a scientific basis for the future application of the concept of plant effectiveness to the ecological risk assessment of heavy metal contaminated soils.
