保护陆生生态的土壤铜环境基准研究

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（EC₁₀）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.

Study of soil environmental criteria of copper for protection of terrestrial ecosystem

The 10% effect concentration (EC₁₀) 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.
