摘　　要：针对指示生物在环境重金属污染监测、评价与防治中所起的指示作用与研究现状,介绍了有关指示生物的基本理论,分析了常见指示生物对土壤、水和大气环境重金属污染的指示作用。提出了选择合适的指示生物是发挥其对重金属污染指示作用的关键。最后,提出了指示生物对环境重金属污染指示作用的局限性及对策。The indicative function of biological indicators in the monitoring, assessment and prevention of environmental heavy metal pollution and its research status are reviewed. The fundamental theory of biological indication is introduced. The biological indicative function for soil, water and air pollution is analyzed. The selection of appropriate biological indicators is the key to play the indicative function of biological indicators. The limitations of biological indicators are pointed out, and the countermeasures are proposed.
