区域沉积物质量基准常用建立方法的改进与优化

建立区域沉积物质量基准（SQC）具有重大的社会、经济和环境价值。本文选择两种当前流行的基准建立方法，相平衡分配法（EqP）和质量三合一法（Triad），重点阐述在指标选择与定量、误差模拟校正、模式拟和运算等实施操作方面各自的改进与优化。同时探讨了SQC的发展趋势以及在污染沉积物治理与恢复决策中的作用。

Modification and optimization of current approaches for sediment quality criteria

Regional sediment quality criteria (SQC) was of great value for the public and aquatic ecological system.In this paper,two current approaches for SQC establishment,i.e.EqP and Triad,were selected to demonstrate the development of modification and optimization during performance on their indices quantification,deviation correction and model simulation.Furthermore,the future tendency of SQC establishment and the role of SQC both in management of polluted sediments and in decision making for redemption were discussed.
