摘　　要：城市化所导致的土壤环境恶化已成为影响居民健康的一个重要因素,土壤的重金属污染问题已成为研究的热点。该文综述了目前常用的土壤重金属污染生态风险评价方法 [形态分析法、TCLP(Toxicity characteristic leaching procedure)法、体外试验评估法、植物培养法、蚯蚓生态毒理法]。指出今后的研究重点是制定土壤重金属环境质量标准和建立完善的评价体系,确定植物重金属污染指示作用的重要性,利用地理信息系统(GIS)技术开展重金属污染填图及建立土壤重金属污染信息系统,这些研究可为土壤管理提供科学指导依据。With the development of urbanization, more and more attention has been given to the influence of heavy metal pollution of soils on urban eco-environment and human heath. This article described the methods for heavy metals pollution ecology risk assessment such as speeiation analysis method, TCLP （toxicity characteristic leaching procedure） test, in vitro digestion models, planting method, earthworm toxicity test. The urgent study includes developing the environmental quality standards for heavy metals levels in urban soil and establishing a maturity evaluation system for heavy metal pollution, confirming the importance of the indicator plants for heavy metal pollution, using GIS technology to carry out mapping of heavy metal contamination in soil, establishing the information systems for heavy metals contamination of urban soil. These studies are important to manage urban soils and control soil pollution.
