集约用海对海洋资源影响评价方法研究

Study of evaluation impact of coastal land reclamation on marine environment

本文通过定性与定量相结合的方法建立了集约用海对海洋资源影响评价指标体系。在该体系中,分别以港航资源、旅游资源和渔业资源为主导因子,运用层次分析法(AHP)和德尔菲法(Delphi)结合的方法来确定了不同主导因子影响的综合指标权重,提出了集约用海对海洋资源影响的评价标准。应用收集的曹妃甸集约用海2005~2015年港航资源、旅游资源、渔业资源、空间资源和其他资源指标数据对曹妃甸集约用海的影响进行了评价,标准化了指标值,确定了指标的综合权重。评价结果表明:2005~2008年海洋资源受影响程度为一般,属于有条件接受状态;2009~2011年海洋资源受影响程度为较小,接受程度属于可接受状态;2012~2015年海洋资源受影响程度为一般,接受程度属于有条件接受状态。

This study is undertaken to develop an evaluation system to assess the effects of coastal land reclamation on marine resources with the combination of both qualitative and quantitative methods. The leading factors include port resources,tourism resources and fisheries resources,and the weights for evaluating indexes are obtained with both AHP and Delphi methods. The evaluation standards for the coastal land reclamation project of marine resources in Tianjin Binhai District have been proposed in this study. With introducing these new evaluation standards,the effects of the land reclamation on marine resources in Caofeidian are evaluated. It is found that in 2005 ~ 2008 the impact of the coastal land reclamation on the marine resources is general and in the state of the conditional acceptance; in 2009 ~2011 the impact is small and acceptable; and in 2012 ~ 2015 the impact is similar to that of the 2005 ~ 2008.
