摘　　要：由于地质沉积物中重金属Cr,Ni污染问题日益突出,对生态风险评价不精准就无法彻底解决重金属Cr,Ni污染问题。针对这一问题,进行地质沉积物中重金属Cr,Ni污染现状及生态风险评价研究。通过分析地质沉积物中重金属Cr,Ni污染现状,得出地质沉积物中重金Ni不仅会污染水体和土壤,还会影响大气质量;计算地累积指数,模拟重金属Cr,Ni生态风险,完成地质沉积物中重金属Cr,Ni生态风险评价,致力于为环境容量、环境质量的研究提供基础数据。Due to the increasingly prominent problem of heavy metal Cr and Ni pollution in geological sediments,the problem of heavy metal Cr and Ni pollution cannot be solved completely without accurate ecological risk assessment.In view of this problem,the current situation and ecological risk assessment of heavy metals Cr and Ni in geological sediments were studied.By analyzing the current situation of heavy metal Cr and Ni pollution in the geological sediment,it is concluded that heavy metal Ni in the geological sediment will not only pollute water and soil,but also affect the air quality;calculate the land accumulation index,simulate the ecological risk of heavy metal Cr and Ni,complete the ecological risk assessment of heavy metal Cr and Ni in the geological sediment,and strive to provide basic data for the study of environmental capacity and environmental quality.
