在综合数据库ＣＥＲＰＤＢＭＳ支持下，利用水体沉积物质量三合一工具（Ｔｒｉａｄ），初步建立江西乐安江表层沉积物中重金属污染的质量控制基准（ＳＱＣ）．通过将化学分析（Ｃ）、毒性鉴定（Ｔ）和底栖群落结构变化（Ｂ）三基元集成为一体的三轴图和相应的响应信息判断矩阵，基于现场生物响应的沉积物质量基准能较为清晰地指示乐安江流域表层沉积物中重金属污染的相对程度和分布模式，体现底栖生物对沉积物重金属污染的剂量响应关系，为进一步制订该区域沉积质量管理标准（ＳＱＳ）、开展后续的污染治理与恢复工程提供技术保证和科学依据．
Under the support of CERP-DBMS, the quality control standard (SQC) of heavy metal pollution in the surface sediments of Le’an River in Jiangxi Province was established by using the triad of water sediment quality. Based on the triaxial maps of the three elements of chemical analysis (C), toxicity identification (T) and benthic community structure change (B) and the corresponding response information judgment matrix, based on the on-site biological response of the sediment mass reference energy The relative degree and distribution pattern of heavy metal pollution in surface sediments of the Le An River Basin are clearly indicated. The dose-response relationship of benthic organisms to heavy metal pollution of sediments is reflected. In order to further develop the SQS standard, Pollution control and restoration project to provide technical assurance and scientific basis.
