摘　　要：通过调研国内外Cu生态毒理研究,收集并筛选土壤Cu的10%效应浓度(EC_(10))和无效应浓度(NOEC),分组构建陆生植物/无脊椎动物和土壤生态过程的物种敏感性分布模型(SSD),结合模型平均法推导不同土地利用方式下重金属Cu的生态安全阈值.针对保护陆生植物/无脊椎动物,自然保护地和农业用地土壤、公园用地、住宅用地和工/商用地的土壤Cu生态阈值分别为10.9~38.9,21.0~77.5,36.6~124,47.6~151mg/kg;针对保护生态过程,自然保护地和农业用地土壤、公园用地、住宅用地和工/商用地的土壤Cu生态阈值分别为4.49~72.2,19.9~135,60.9~220,96.8~277mg/kg.The 10%effect concentration(EC_(10))and no effect concentration(NOEC)of Cu eco-toxicity were collected and screened from toxicity database and the published literature.Species sensitivity distribution(SSD)was performed to construct the SSD models for plants/invertebrates and ecological processes.The soil ecological safety thresholds were derived based on the model averaging method.For protecting the plants and invertebrates,soil thresholds of Cu were 10.9~38.9,21.0~77.5,36.6~124 and 47.6~151mg/kg for natural reserve/agricultural land,park,residential land and industry/commercial land,respectively,while soil thresholds were 4.49~72.2mg/kg(natural reserve/agricultural land),19.9~135mg/kg(park),60.9~220mg/kg(residential land)and 96.8~277mg/kg(industry/commercial land)for considering the soil microbial community.
