曹妃甸围填海工程的环境影响回顾性评价

围填海回顾性评价是一项涉及面广、内容复杂的分析评价工作。要做出准确、科学的评价,就必须有一套科学的后评价方法和指标体系,评价出项目实际目标与可行性研究阶段预测情况的偏离度,从而比较客观地做出评判。文章建立了围填海工程的海洋生态环境影响回顾性评价指标体系、评价标准与评价方法,并综合运用层次分析法对曹妃甸围填海工程的海洋生态、水动力环境、水质环境和底质环境影响进行回顾性综合评价。该方法克服了传统定性评价的主观性缺点,从而得出比较客观、科学的评价结果,为衡量和分析曹妃甸围填海工程对海洋环境的累积影响及后期围填海工程的环境管理与决策提供了依据。

Post Project Environmental Retrospective Evaluation of Reclamation in Caofeidian

Post project analysis of the reclamation project is one of evaluation which involves a broad of subjects and study fields. Therefore, a scientific evaluation method and index system is necessary to accurately assess the devation of actual impact and prediction impact. In this paper, AHP is employed to retrospective evalue impact of reclamation project on hudrodynamic environment, water environment, sediment and marine biology commnuties in Caofeidian. Firstly, some index of marine biology, hudrodynamic environment, water environment and sediment environment was chose and a system of retrospective evaluation mothed was established. Then impact of reclamation project in Caofeidian on marine enviroment was retrospectively evalued. This mothed overcome shortcomings of traditional subjective evaluation and obtain a more objective, scientific evaluation for marine environment measurement of reclamation project in Caofeidian, lately.
